It has the latest version of cygwin that still supports XP (2.874). This system isn't on the internet very often. It is still of interest to me to understand how the components of cywgin work and what controls such things as how and why IPC may be triggered. This is especially true when I see behavior that doesn't make sense to me. I don't see any reason why bash should need to communicate with svchost every time it is run, especially where blocking that communication has no discernible effect. If this is evidence of a system problem somewhere, I of course would like to know about that as well.

another question about cygwin bash trying to make connections
Hello, Every single time run bash in a terminal, I get the following firewall alerts, C:\cygwin\bin\bash.exe An attempt to communicate a foreign process has been detected. Target PID: 1616 Image Name: svchost.exe C:\cygwin\bin\bash.exe A potential threat to network traffic interception or injection has been detected. This is when running a script that invokes bash with the shebang. The same thing happens if I just run bash with no arguments. On every run of bash, bash tries to IPC with svchost.exe. The second alert for network traffic injection suggests that bash.exe is attempting to use svchost to make a network connection. This is common enough since svchost.exe has unfiltered network connection permission on most systems (stupid in my opinion). I have looked in all of the versions of .bashrc and .bash_profile and don't see anything there that looks relevant. I presume that bash is trying to do something like check to see if it needs to be updated. In that case, I have never understood why bash.exe needs to try to connect through another process instead of just making the connection itself. If this is something else, well, who knows. The attempted IPC is entirely unnecessary as blocking both alerts has no effect whatsoever. How should I go about trying to run this down? I can just create the rule to permanently block the IPC and network traffic injection, but I would prefer to stop the connection attempt from what is triggering it. That would allow me to see new alerts if it happens again. This is the version of bash, GNU bash, version 4.3.42(4)-release (i686-pc-cygwin) it would be very helpful as a first step if I could find a verified digital signature for this version of bash. The index here, https://ftp.gnu.org/gnu/bash/ gives an archive of bash with a signature for each tar.gz but not the signature for each version of the extracted binary.

why is mintty trying to connect to google through my browser
Hello, I had an odd thing happen today. I opened a cygwin terminal to do something and got a firewall alert that mintty was attempting to inject network traffic. I did a temporary deny because there is no reason for mintty to make a connection based on what I was doing and I have never seen that alert before (or I would have a firewall rule already). That alert doesn't say where the connection would be made to if the injection was allowed. This temporary block seemed to break my seamonkey connection. My firewall log is full of entries about blocked connections for seamonkey and the reason given is "restricted parent process c:\cygwin\bin\mintty". I did not launch seamonkey using mintty, so I have no idea why the firewall would see mintty as the parent process. All of the seamonkey attempted connections to my email server were also blocked for the same reason. When I closed the terminal, everything went back to normal. It seems like mintty tried to inject some network traffic to the seamonkey process and for some reason, blocking this injection caused the firewall to block all traffic from seamonkey. Why would mintty try to inject network traffic to another process at startup? If it needed ot connect for some reason, why would mintty try to make that connection through another application instead of just making the connection itself? I deleted any firewall rules for mintty and started the terminal again, but that does not reproduce the situation at the moment. I believe this is cygwin 2.3.1.

is it normal for bash.exe, sh.exe, and uname.exe to IPC with svchost.exe
Hello, I am trying to run down some odd behavior on my system. I have reset my firewall to "ask" for most operations and am trying to rebuild my rules. While running a bash script that I wrote, I get notifications from my firewall that bash.exe, sh.exe and uname.exe are attempting inter-process communication with svchost.exe. I also get a notification that a potential threat to network traffic interception or injection has been detected for the same processes. Blocking this IPC does not appear to affect anything in how my script runs, so I am wondering what the purpose of the communication is. The bash script does not make any connections. I have observed that software that is trying to bypass a firewall and find a back way onto the internet will often attempt to use svchost.exe to make the connection because svchost.exe is often given free access by default. Is there some reason I should be expecting these processes to talk to svchost.exe?

This code often isn't worth the expenditure to bring up to date. As long as the compiled binaries still run on current systems, the code won't get updated unless the update is a minor fix. You can have as many cygwin installations on your system as you want, just name the root folder and install folder something different for each one. There are potential problems if you try to run more than one version at the same time. I have had different answers on this but I don't do it in case there may be problems that aren't evident. I start the older cygwin terminals using a .bat file that configures the /cygwin/bin PATH environment variable for the version of cygwin I are running. The .bat file looks like, @echo off :: remove "C:\cygwin\bin" from PATH set "PATH=;%PATH%;" set "PATH=%PATH:;;=;%" set "PATH=;%PATH:;C:\cygwin\bin;=;%;" set "PATH=%PATH:;;=%" :: create a local environment variable for the alternate cygwin version (cygwin2) set "PATH=C:\cygwin2\bin;%PATH%" start "" /b C:\cygwin2\bin\mintty.exe -i /Cygwin-Terminal.ico - I leave this .bat file in the install directory for the alternate cygwin and have a shortcut on my desktop that runs the bat file. When I want to start an alternate version of cygwin, I just click on the icon I want. I also have modified the terminal settings so that the background color of the bash window is different for each version I have installed. That reminds me of what version of cygwin I am in. If this is something you really need, like everything else, keep a backup copy of the cygwin root directory and install directory. The time machine site has worked for me in the past, but it was very slow. You probably will want to download using wget and be prepared to leave going it all day.

I looked for the syntax for this when I first started. I assumed the the

have my make file in the src directory when using gnu make, so this
looked the same to me. I didn't find any doc about how to have the
CMakeLists.txt and the src in different directories.
Csaba was clear but it seems you are misunderstanding,
the call to cmake is
cmake [options]
so I will put together his suggestion and Tony's one:
$ git pull https://bitbucket.org/tomilov/quickhull/src
$ ls src/
CMakeLists.txt include README.md src test
$ mkdir build
$ cd build
$ cmake -DCMAKE_CXX_COMPILER=clang ../src
the "build" directory is in this case parallel to the "src" one.
Unfortunately it will fail on "Compiler does not support C++1z standard"
and you will need to modify the original CMakeLists.txt.
I cut

-CHECK_CXX_COMPILER_FLAG("-std=gnu++1z" COMPILER_SUPPORTS_CXX1Z)
-if(NOT COMPILER_SUPPORTS_CXX1Z)
-message(FATAL_ERROR "Compiler does not support C++1z standard")

problem building with cmake under cygwin (need clang)
Hello,
I am trying to compute the convex hull of a high dimensional space (46D x 2000 rows).
The qhull app available in cygwin/math is based on relatively old code and runs out
of memory.
I found another version the is supposed to be able to do higher dimensions.
https://bitbucket.org/tomilov/quickhull/src
This version is set up to build with cmake, so I installed cmake in cygwin and
ran it as,
cmake ./src
Note, I had to copy CMakeLists.txt into the src directory to get this to work. If I
don't do that, I get the error,
CMake Error: The source directory
"/cygdrive/g/shared_data/SMD/ATomilov_quickhull/tomilov-quickhull-7faf277d6cc2_cmake/src"
does not appear to contain CMakeLists.txt.
When I have copied the CMakeLists.txt file into ./src, cmake runs but I get the
error,
CMake Error at CMakeLists.txt:11 (message):
only clang supported currently
this comes from the conditional,
if(NOT "${CMAKE_CXX_COMPILER_ID}" MATCHES "Clang")
message(FATAL_ERROR "only clang supported currently")
endif()
in CMakeLists.txt.
I have installed clang from cygwin, but I still get the same error. I added the
following line to CMakeLists.txt,
message(STATUS "${CMAKE_CXX_COMPILER_ID}")
and I get "GNU" as the value for CMAKE_CXX_COMPILER_ID, at least that is the value if
I got the syntax correct for the message statement.
It looks like I need to point CMAKE_CXX_COMPILER_ID to clang, but I am not sure how
to do that. I don't know if the problem is with the CMakeLists.txt file, the way I am
calling cmake, or with my local cygwin configuration.
Suggestions would be appreciated.

Re: using fortran common block from dll created by gfortran
If you having trouble communicating with the dll, it might make more sense to create a generic c dll and embed the fortran in the c dll as a subroutine. It is generally not a problem to call a fortran subroutine from c code though there are some syntax specifics to follow. Your communication with the dll could follow standard c protocols. Since c code and fortran code will have their own namespaces, your fortran includes, common block, etc, shouldn't be a problem since those variables will only be linked to the fortran objects. Your fortran src files will be run through the fortran pre-processor so your common block should be fine. Your c src files will be run through the c pre-processor. The c objects won't know anything about the fortran global variables but you can exchange what you need to between the c and fortran in the call to the fortran subroutine. You end up with two copies of allot of things but this is a decent way to get fotrran code to talk to the modern programming world. The only way I know to use the same memory namespace for both c and fortran files is to run the fortran through the c pre-processor (name your fortran src files .FPP). This lets you use c style includes and compiler directives in your fortran code but does not support a common block. You would have to declare global variables in c style includes.

Hello Csaba,
Thanks for the information. I will take your advice and unpack Eigen in
/usr/local/include/eigen instead of in /lib and drop the /cygdrive/c/
from the include path.
As I mentioned in an earlier post, Eigen is not a compiled library,
meaning there is no binary file. As I understand it, you are just
supposed to use the src code and header files as is, like you would use
any other .cpp and .h files in your build. The main difference is that
the files are not located in your trunk src directory.
Yaakov Selkowitz mentioned that Eigen is available through ports. I have
never used ports, so I'm not sure what the difference is. Is there a
difference in the way the Eigen code gets linked to my app if I install
Eigen through ports?
According to the Eigen page, Eigen isn't installed in the formal sense,
like you would install boost through the cygwin package manager. You
just put the Eigen folder somewhere and add the top level to the include
path. When you write your src, you add includes for the header files you
want and compile/link as normal.
"If you just want to use Eigen, you can use the header files right away.
There is no binary library to link to, and no configured header file.
Eigen is a pure template library defined in the headers."
This is a sample program from the getting started page,
## my_program.cpp ##
#include
#include
using Eigen::MatrixXd;
int main() {
MatrixXd m(2,2);
m(0,0) = 3;
m(1,0) = 2.5;
m(0,1) = -1;
m(1,1) = m(1,0) + m(0,1);
std::cout << m << std::endl;
}
g++ -I /path/to/eigen/ my_program.cpp -o my_program
According to the same page, if you have the Eigen folder, or a symlink
to the Eigen folder, in /usr/local/include/, you don't need to use -I.
So I guess I still need to figure out if this is going to work as I
understand it and if there is some advantage to installing Eigen through
ports instead of just unpacking it.

I guess my understanding of eigen is that it not a library that is linked to and then accessed dynamically at runtime but rather is an archive of cpp src code and header files. You use it by including the header files for the functions you need and the linker bundles the code specified in the header files into your application. This works no differently than the other src and header files for your program. There is no config or make files included with eigen with which to configure, build, or compile anything. >From the Eigen site, "How to "install" Eigen? In order to use Eigen, you just need to download and extract Eigen's source code (see the wiki for download instructions). In fact, the header files in the Eigen sub directory are the only files required to compile programs using Eigen. The header files are the same for all platforms. It is not necessary to use CMake or install anything." "There is no library to link to. The only thing that you need to keep in mind when compiling is that the compiler must be able to find the Eigen header files. The directory in which you placed Eigen's source code must be in the include path. With GCC you use the -I option to achieve this." I wouldn't have posted this question if I was at all clear on how this is supposed to work, so the above is just my current understanding. It may be entirely incorrect. Do you think I am misunderstanding how this is supposed to work?

advice about setting up the eigen library for use with cygwin g++
Hello, As stated, I am writing a few tools with cygwin g++. These tools will make use of the eigen library for some linear algebra (PCA and matrix manipulations). I have never built with a library that was not installed through the cygwin package manager, so I thought I would ask if there was anything I needed to be aware of. Eigen is a header only kind of thing, so my understanding is that all I need to do is to unpack the src somewhere add the location to the include path. I was thinking of putting Eigen in, /cygdrive/c/cygwin/lib/eigen/ and using, g++ -I /cygdrive/c/cygwin/lib/eigen/ Does anyone see any issue with this approach? Will there be a problem having a non-cygwin directory in cygwin/lib, meaning something the cygwin install isn't formally aware of? Is there a preferred method for setting up something like this?

Thanks for the advice. I went to using something like,
FILE_LIST=($(ls
'./'$SET'/'$FOLD'/'$FOLD'_anneal/'$PARAM_SET'/'$AN_SET'/'*'out.txt' ))
instead of,
FILE_LIST='./'$SET'/'$FOLD'/'$FOLD'_anneal/'$PARAM_SET'/'$AN_SET'/'*'out.txt'
when I was creating a script because ls will throw an exception if there
is nothing found matching the glob. This is especially true when I am
using a long path with allot of variables. I often remove the ls once I
know the script is working. The the first syntax above also creates an
array.
FILE_DIR was assigned separately because it it used in some other places
in the script and convenient to have in scope.
I have also had problems evaluating strings that were created by
assigning with a glob.
If I had a file,
myfile_1.txt
and did,
file_name='myfile_'*'.txt'
and then,
if [ "$file_name" = "myfile_1.txt" ];
I have had issues getting the above conditional to evaluate as true.
If instead I do,
file_name=$(ls 'myfile_'*'.txt')
the conditional will evaluate properly.
Am I mistaken about this? I have not taken the time to run down all of
these issues when they occur, which I really should.

Good Lord, I guess I wasn't thinking very clearly trying to use PATH as
a variable for something else. I changed to,
FILE_DIR=$(ls -d './'$SET'/'$FOLD'/'$FOLD'_anneal/'$PARAM_SET'/'$AN_SET)
echo $FILE_DIR
FILE_LIST=($(ls $FILE_DIR'/'*'out.txt' ))
echo ${FILE_LIST[@]}

cygwin bash script suddenly can't find ls, grep
Hello,
I have been working on a bash script and suddenly I started getting an
error that ls could not be found,
./remove_rows.sh: line 27: ls: command not found
I can run ls from the command line just fine. There is also an ls
command before line 27 that runs fine. This is the part of the script
that is causing problems (line numbers are included).
24 PATH=$(ls -d './'$SET'/'$FOLD'/'$FOLD'_anneal/'$PARAM_SET'/'$AN_SET)
25 echo $PATH
26
27 FILE_LIST=($(ls $PATH'/'*'out.txt'))
28 echo ${FILE_LIST[@]}
The echo $PATH command gives the correct output, but I get the error on
line 27. I have tried without the double parentheses, which wouldn't
give the result I want,
FILE_LIST=$(ls $PATH'/'*'out.txt')
but this gives the same error.
After this problem happened, I updated cygwin and restarted, but the
issue persists. Is there something wrong with my cygwin install? If
there happens to be some problem with my bash, please let me know, but
this is pretty simple stuff and I just can't see why ls would be found
at line 24 but not line 27.
The test script worked many times before this error and I didn't change
that part of the script that is causing the error.

This is an older setup and there are critical components in the build that are no longer available in more recent cygwin packages. If I let cygwin just do it's thing, it will break far more that it will fix. Updating the entire cygwin install would mean moving to more recent versions of multiple packages and who knows how much time, effort, and resources would be involved in fixing all of that. At the moment, the server does exactly what it needs to in its current configuration, so there is little sense in wading into the quagmire of updates when there is little or noting to be gained. There are some post processing steps to what the server does that need a newer version of ruby. It would be nice to have to post processing done on the same server, but it is not essential. If I can update ruby without breaking everything else, than that is worth doing. It is not worth attempting to update everything just to add the post processing. I apologize for being tiresome and obtuse, I'm sure that can be quite a bore from your end of things. I still don't seem to get all of this. There are terms here like "archive" and "mirror", and "archived mirror" that still evade me. In the cygwin install on this machine (with an internet connection), I have an install directory with, 1. setup-x86.exe 2. several local package directories http%3a%2f%2fcygutils.fruitbat.org%2fITP%2fmingw-gcc%2f http%3a%2f%2flug.mtu.edu%2fcygwin%2f http%3a%2f%2fmirror.cs.vt.edu%2fpub%2fcygwin%2fcygwin%2f http%3a%2f%2fwww.gtlib.gatech.edu%2fpub%2fcygwin%2f Are these package directories the mirror or archive you are referring to. I know I can use the package directories to install on another computer because I have done that. Am I supposed to download an entire release directory from one of the cygwin mirror sites or can I use one of the local package directories listed above. What I did the last time was to create a new cygwin install on this machine with its own setup.exe and install directory. I had some problems moving to another machine when the install I was copping has multiple local packages. I only ever got a partial install doing it that way. If I created a new install with only one local package, I could then move the instal directory to a new computer and install there pointing to a local package. That was for a new install, I have never done anything comparable to update an existing installation. Is that more or less what I am supposed to do? This is to update a server that does not have an internet connection in case I didn't make that clear.

You said, "grab the current setup.exe" Do you mean download the most recent one, or one from another machine with an internet connection?

update just ruby on offline cygwin installation
Hello, I have cygwin running on a box that does not have an internet connection. I would like to update ruby to 1.9.3p448 to make it compatible with some of my newer scripts. I'm not sure how to do that without updating the entire installation, using a new installer, etc. This is a fairly old install before mintty was the default terminal. It would also be nice to switch to mintty if that is also possible under the same circumstances.

Re: 32 and 64 bit cygwin on same machine?
I have run multiple versions of cygwin on the same machine. In my case, both versions were 32-bit, but I don't see how that would make a difference. You need to make sure that the environment variable for the path to cygwin.dll is correct so the 64-bit dll gets loaded when you open a 64-bit terminal. I did that my using a windows .bat file that starts the cygwin shell and creates a properly configured local environment. This is the .bat file I use, :: This bat removes the C:\cygwin\bin PATH environment variable for the cygwin1 install that is :: loaded into the cmd shell environment block from the registry. The C:\cygwin2\bin PATH environment :: variable for the cygwin2 install is then added to the PATH for the environment block. A mintty :: terminal is started from within the cygwin2 installation. The mintty process inherits the :: modified environment block. When the bat file closes, a mintty terminal (running bash) is left :: and has the proper PATH environment to run from the cygwin2 installation. @echo off :: remove "C:\cygwin\bin" from PATH set "PATH=;%PATH%;" set "PATH=%PATH:;;=;%" set "PATH=;%PATH:;C:\cygwin\bin;=;%;" set "PATH=%PATH:;;=%" set "PATH=C:\cygwin2\bin;%PATH%" start "" /b C:\cygwin2\bin\mintty.exe -i /Cygwin-Terminal.ico - I think you could use something similar, just make sure to name your cygwin installation and local package directories differently for the two installs. Of course, you could just move your 32-bit cygwin off the machine, deleted the cygwin path variable, and install the 64-bit version. It's not hard to move the original version back later.

Re: g77 on cygwin64
What host operating system are you running cygwin on? Do you have examples of your old g77 applications that are already compiled that you can test on your current system? There are several options. Compiling g77 is one of them, but you would need the proper runtime components as well. It is also possible to have more than one cygwin installation. You can have an older x86 cygwin installed that still has g77. The question is weather or not an app compiled with g77 under 32-bit cygwin will run on your OS. You also would not be able to run both versions of cygwin at the same time. A think a bit more information would be useful. This is the gnu archive page for gcc version 3.4.6, which I think is the one that is most compatible with the gcc 4 stuff. http://ftp.gnu.org/gnu/gcc/gcc-3.4.6/ If I remember right, you could not compile with 3.4.4 once your cygwin had been updated to gcc 4. There were some collisions and header issues. I think that had been fixed by 3.4.6, but cygwin had moved on from gcc 3 by then and they never released a package past 3.4.4. I think you can get it compiled and it would probably be better to consult with the gnu message board about that, since that's there thing. If you think it would be useful to try installing a second cygwin, I can send you some notes for that. LMH Scott T.

I realize that g77 is now deprecated by gfortran, but I have a lot of old fortran 77 code that does not compile correctly with gfortran. Since I am not a fortran coder (I mainly use interpreted languages), I do not have the skills to figure out what the issues with gfortran are.

'-std=STD' Specify the standard to which the program is expected to conform, which may be one of 'f95', 'f2003', 'f2008', 'gnu', or 'legacy'. The default value for STD is 'gnu', which specifies a superset of the Fortran 95 standard that includes all of the extensions supported by GNU Fortran, although warnings will be given for obsolete extensions not recommended for use in new code. The 'legacy' value is equivalent but without the warnings for obsolete extensions, and may be useful for old non-standard programs. The 'f95', 'f2003' and 'f2008' values specify strict conformance to the Fortran 95, Fortran 2003 and Fortran 2008 standards, respectively; errors are given for all extensions beyond the relevant language standard, and warnings are given for the Fortran 77 features that are permitted but obsolescent in later standards. '-std=f2008ts' allows the Fortran 2008 standard including the additions of the Technical Specification (TS) 29113 on Further Interoperability of Fortran with C. Yup, I tried that compiler flag (-std=legacy) with gfortran. No luck. Back when cygwin was x86 only and had g77, the same code compiled correctly and ran fine. I have the same issues on Linux boxes, so the gfortran issue is not unique to cygwin. The solution I found was to dig up the old binaries for my Linux boxes and install g77 on them. I don't think I can do this for cygwin since g77 was never a part of cygwin64. Would it be very difficult to take the old g77 source and recompile it for cygwin64?

Re: Ok, then
These are good guides for learning something about shell scripting, http://linuxcommand.org/ http://www.howtogeek.com/67469/ This is also good, but more extensive and focused on bash, http://www.tldp.org/LDP/Bash-Beginners-Guide/html/ One of the nicest things about learning to use cygwin and the bash shell is that it will make linux much more accessible if you ever want to go that route. Other than shell scripting, the concept of a package manager is the other main thing you will need to gt well in hand. The cygwin installer functions more or less as a package manager. Windows generally doesn't require the user to be involved in managing the underlying tools, libraries, etc, that allow software to run. In most cases, you just install software and the engineer who created the software takes care of making sure it runs. In linux, there are often dependent components that need to be installed to get an application to run. A package manager helps to control that aspects of software management. When you install an application with a package manager, the manager will check to make sure that everything the application needs is present and install additional components if necessary. Packages that appear in the cygwin installer are maintained by volunteers who add updates to applications and dependent components and keep everything working. Installations can be made outside the package manager, but then you have to configure the dependencies your self. If you choose something to install in the cyginw installer, you will often be shown a window listing additional components that are also going to be installed. It would be a good idea to read up a bit on package managers, but that info may be a bit harder to find than info on something like bash. LMHmedchem Jonathan Martin wrote: FANTASTIC!

Should I demand an IBM-360 Fortran 4 compiler being distributed? :-) That is not a rhetorical question, so if there are some good reasons to move to newer versions of gcc, I would be interested in hearing the arguments. Putting in time to revise code and end up with the identical assembler is not something I am all that interested in. Identical assembler? Come on, do you want your executables optimized for i486 ? Then yes, you might want to us gcc3. :-) Also it's obvious that most of Fortran 77 code had been developed not on g77, but using other compilers, mostly dead by now. After all, being a cross-compiler, g77 is mostly a quick hack. Dmitrii Dmitrii, thank you for the thoughtful response. I really am looking for information here. Allot of the fortran code that I use was actually written in the 70's (on punch cards), so those systems are long gone as well. I used Absoft for a while as well before moving to cygwin with gcc. Since this code is so old, most of it is very, very, serial and very simple (primitive data types, conditionals, and do loops). For such simple code, I don't imagine that the assembler coming out of a compiler today is all that different than it was a long time ago. Of course I could be very wrong, and that is why I ask questions. My only point about gfortran 4.0 was to illustrate that moving to a new compiler can result in unforeseen problems. That can mean expending resources to fix a self created problem. Just try go to get a corporate IT director to migrate to a new OS version and you'll get a 10 hour litany of everything that is likely to go wrong and how much it will cost to fix it. I have associates at very big companies that are still using Cent4. Why? Because everything they do works on Cent4, so why wade into the mire of an upgrade? An OS is a different level of messy than a compiler, but the principle is the same. The header files are never going to change on gcc3. Everything I have that compiles on gcc3 now will always compile on gcc3. I can't say the the same for gcc4. I do have gcc4 installed and use it all the time. I just don't use it for everything. I have done extensive testing and all of my older stuff runs just as fast when built with gcc3 as when built with gcc4. If there comes a point where gcc3 based apps will no longer be compatible with more modern runtime components, or something like that, that that is another story. Stable code that does not require allot of maintenance is a beautiful thing. Maybe it's time that I updated everything to gcc4, but I am reluctant to spend a month or more to do that when it's not clear to me what the be

Thanks for the information. I am tying to get the packages using the Time Machine, but all I am getting is an error, "unable to get setup.ini" from the different ftp addresses I have tried. I sent an email to the link at the bottom of the page, so hopefully they will be able to help me with that. I am interested in whether or not there is some good reason for not using gcc3 anymore, but perhaps this is outside the bounds of this list. I would also like to know why setup-x86.exe is configured to find and physically remove the gcc3 packages. It's like someone decided, "you're not allowed to have those anymore, so we are going to take them away". Since the compiler bin was already labeled gcc-3/g77-3, why would it have been a problem to leave the the bin files where they were? It doesn't appear as if they would have caused a problem. My make files were already configured to point to gcc-3 and not to whatever "which gcc" would return. Someone always has to decide how these things will work, and I assume that is not easy in all instances. Still, I would expect there to be a very good reason why someone would go to the bother of trolling around in someone's file system and get rid of things that the user put there intentionally. If there isn't a compelling reason, I would find that rather odd and worth some discussion.

Re: offline cygwin install question
I don't see why. If the directory is duplicated precisely I don't see how it could matter. What I was referring to here was to just copy the cygwin local package directory that contains setup.exe and the http% mirror directories, not the directory that contains installed cygwin. When I moved the local package directory to a new machine and ran setup.exe with install from local directory, there sometimes were problems. If there was only one http% directory /http%3a%2f%2fwww.gtlib.gatech.edu%2fpub%2fcygwin%2f /setup.exe /setup.log (meaning all of the cygwin install on the machine where I took the setup.exe dir from had been done from the same mirror) then running setup.exe worked fine and I got a functional cygwin. If found that if there were several mirror directories, /http%3a%2f%2fcygutils.fruitbat.org%2fITP%2fmingw-gcc%2f /http%3a%2f%2fmirror.cs.vt.edu%2fpub%2fcygwin%2fcygwin%2f /http%3a%2f%2fwww.gtlib.gatech.edu%2fpub%2fcygwin%2f /setup.exe /setup.log then running setup.exe would install only the packages in the last mirror used and there would be a number of things missing from the install (like the cygwin.dll). I did this before I knew that I could just move the entire installed cygwin directory to a different machine. Regarding this set of instructions, http://cygwin.com/ml/cygwin/2013-06/msg00657.html they seem to be a bit more involved than is necessary. My cygwin install directory is less than 1GB, so what is the need to use tar? I believe that when I last re-installed my current OS, I just copied my cygwin folder to a backup drive and then copied it back to C: after my re-install. Is there some reason why that is a bad idea?

Re: offline cygwin install question
I have win7 64-bit computers set up in another location. It would seem that the easiest option would be to make sure that one of those is up to date and then just tar up the cygwin directory and move it. I have also found that you can just tar up the local package directory and then run a local install, but this seems to have issues if there are packages in the local install dir from more than one mirror. If I download the normal setup.exe to a 64-bit windows install, will it automatically install the 4-bit version? have never seen the setup64.exe that was mentioned in a previous post. Where would that be located? I have to assume at this point that the cygwin I have running on w7 64-bit installs is the 32-bit version of cygwin, since I didn't do anything special when I set those up. I know that many 32-bit applications run perfectly well on a w7 64-bit install. What specific advantages would there be in running the 64-bit version of cygwin? The main thing I want to do is to upgrade to the minty terminal and make sure I am using the most current version of cygwin. I think that the version on this rig is pretty old.

how to use cygwin to grant windows full control (xp)
Hello, I have just changed hardware and reinstalled windows. I keep my data on separate drives, but of course I no longer "own" the files. In the past I have just used a combination of chown and chmod -R to change the file ownership and permissions to my new user. This time, I have done this, but it didn't seem to work. I can't move or copy files like I should be able to. I have done, chown -R user_name /dir/ followed by, chmod -R 777 /dir/ I am logged into an administrative user account. I would prefer to not use 777, but I need access to these files and 755 didn't work. If I open the windows permissions, I see that I don't have "full control" over files, and for directories, there are no permissions whatsoever for my username (all check boxes are empty). Can someone point me to a writeup on how to recursively change all directories and files to my ownership and give them reasonable permissions? I would also like to remove the old "unknown user" permissions that are there from my last install if there is a good way to do that.

Re: Replacing fork/exec with spawn question
You will need to use windows pipes as well as the windows version of fork. I have a couple of small apps that do what you are suggesting. What I did was to abstract the functions for creating process and pipes. Abstraction was done in the make file. There are functions like create_new_process(), create_new_pipe(), etc. There are two versions (posix and windows) of each function with the same name, but in different src files. When the app is built, one or the other version of the src file is linked, depending on what os you are in (dual-boot etc). This lets you build your app on multiple platforms from the same code base. This could be done with ifdef or other compiler tools as well. I don't know if I have time today, but I can put together some of the code for you to look at. Suffice it to say that I have cpp apps that work as you suggest, parent/child with pipes for IPC, and they were built for windows using cygwin. They also run under linux if that matters. It may be better to move such a discussion to a programing board since some of this will not relate to cygwin and it would be nice to have things like php formatted code, attachments, etc. The mods here can let us know about that. I have thought at times that some of the code I have here should be made into some kind of IPC API. Perhaps others would find that useful. LMH Devin Nate wrote: Hi folks, I'm looking for some documentation about the cygwin spawn use, or a recommendation of a package that has had fork/exec replaced by spawn that I can review to see how someone else did it. Preferably less intimidating than gcc, and which uses pipes for IPC between parent and child. In particular, the code I'm looking to patch does a typical fork/exec and uses 2 pipes to communicate bi-directionally parent to child. The pipes are throwing me off as to if cygwin spawn is usable. I've been through the spawn.cc code, and see spawn_guts has a concept of __stdin and __stdout, but I don't see those params used by any of the spawn functions.

Re: best way to re-install and keep cygwin configuration
So I will just tar up the cygwin directory and put it back after the new install. If I download a new copy of setup.exe and point it at the install directory, will it figure out what packages are already installed? I suppose I could test this sort of thing, but I figure that someone already knows the answer. Is there any reason to not re-use my current version of setup.exe, minus that setup cache?

some kind of path problem when running bash script from windows shortcut
I have recently re-installed windows and cygwin, but my old backup
script won't anymore when I run it from a windows icon. It runs fine if
I cd to /usr/local/bin and run it from the command line.
When I run it from the shortcut, I get "file not found" for rsync, date,
unix2dos, and rm. I have temporarily changed the script to use the full
path for these, /cygdrive/c/cygwin/bin/date.exe instead of date, but I
have used this setup for a while and I'm not sure what has changed. Am I
missing an environment variable or something?
I'm not sure if the problem is in windows or cygwin.
This is the version of the script that doesn't work from the shortcut,
but does work from the command line.
#!/bin/bash
# generic backup function
function backup {
echo " " >> $1
echo " " >> $1
echo "* new log entry *" >> $1
date >> $logfile_path
rsync -v -a -r -p -b --suffix=.back -E -t --log-file=$1 $2 $3
unix2dos $1
}
logfile_path="path_to_logfile"
backup_src_path="path_to_backup_src_loc"
backup_destination_path="path_to_dest_loc"
backup $logfile_path $backup_src_path $backup_destination_path
The shortcut is set up as,
Target: C:\cygwin\bin\sh.exe /usr/local/bin/backup.sh
Start in: C:\cygwin\bin
Any suggestions?

Re: rsync ERROR: out of memory in flist_expand [sender]
If you are continually copying large numbers of files with rsync, maybe
you would be better off just using cp. Do you need to keep older
versions with the same file name, meaning an incremental backup?
I generally start by just doing a cp of the src directory to the backup
location. When the number of files is large, I just do,
cp -Rfp /src_loc_path/ /backup_loc_path/ &> copylog
This gives me a record of anything that might not have been copied due
to permission issues, etc. It's best to do this from a windows admin
account.
Then I run rsync on subsequent days so that rsync is just dealing with
changes made on any one given day and not trying to copy very large
directories. I always use a log file so I can check to make sure it has
finished and got everything it was supposed to.
#!/bin/bash
function backup {
# write some stuff to the log file
echo " " >> $1
echo " " >> $1
echo "* new log entry *" >> $1
date >> $logfile_path
# run the backup
rsync -v -a -r -p -b --suffix=.back -E -t --log-file=$1 $2 $3
# convert the log file format to windows EOL
unix2dos $1
}
# give a location for the log file, src, and backup loc
logfile_path="/logfile_path/log.txt"
backup_src_path="/backup_src_path/"
backup_destination_path="/backup_destination_path/"
backup $logfile_path $backup_src_path $backup_destination_path
I just have this script attached to a windows shortcut. That way I can
run it with a double click, or add the shortcut to the task manager if I
want to schedule backups. I guess I should be using cron to get the full
quantity of linux points, but I haven't got around to it.
If you wanted to, you could make a script that would check if the backup
destination directory exists, and if it doesn't, just do cp. If it does
exist, then run rsync.
I don't know how much volume it rsync designed to manage, especially if
it needs to keep a connection over a net, but if you are running out of
resources you may want to look at a different tool.
There are other options, like rdiff and unison. I have used unison, but
it is more a mirroring tool and I found the incremental backup options
gave me errors. I you are just trying to mirror directories or machines,
then it is a good tool.

Re: question on Cygwin's version of make
Some folks call make from a bash file to take advantage of things that bash can do and make can't, or at least easily. Using a "config.sh" to run make could let you test anything you want, print warnings, or exit, if anything is spotted. If everything looks good, the script can call make. This is common when you need to collect information about the local configuration (OS, arch, preferences, etc) in a portable way. Don't know if that helps, but that is what occurred to me reading you post.

Re: Rsync stops inmid of synchronisation
One thing to check is the disk drives. I have had rsync stop when it reaches corrupted sectors, especially if those sectors corrupt part of the file system. I don't remember anything helpful in the log files, I just noticed that it wasn't finishing. Try running disk diagnostic software and make sure your hardware is good. What kind of hard drives do you have and what OS? If that doesn't show up anything, I would start by synching just one folder. Create a test folder on both computers and add a few files. Make sure your permissions are correct. Make a change in one file and then run rsync. If it finishes and the logs look good, add more to the test folder and see if you can find where it brakes. You can test things like very large files, and folders with a large number of files. If you can't get it to fail, then the issue may be with the data on one of the computers. The problem may also be with the rsync software, but I can't advise well on that end. LMH Richard Ivarson wrote: Good day, I've successfully used Cygwin and in particular it's RSYNC for many years, for example to sync a Windows XP computer named Sendi to another XP computer named Desti in a local network. Since a few months however rsync is causing me endless trouble. I regularly upgrade to new versions of Cygwin, so I'm up to date with all Cygwin programs. Now I don't know if my network is the problem (it works fine for all other purposes except rsync) or the rsync program (or its configuration). Maybe somebody knows how I could encircle the problem. Here's the details: - Sendi and Desti are connected via a Ethernet cable to a Router - On Desti rsync runs via "rsync --daemon" - On Sendi the rsync task is started with "rsync foldername/ Desti::modulename/" (and module name is configured as described in Cygwin's or rsync's manual) When the rsync tasks start, at first everything runs fine. I see this by following to Desti's rsync log file and Sendi's verbose output, and at the files being synchronisised. Ie the two rsync programs exchange the files which are out of sync -- but unfortunately just up to a certain point. After a number of files have been transmitted -- and this number varies every time I re-start the task (sometimes it's some 1000 files, sometimes less) -- the two rsync programs stop to talk to each other. Sendi's not continuing to send file names anymore. But why? I've increased Sendi's rsync verbose level to maximum but it just stops to print the file names it wants to send to Desti. So I've started Wireshark to see the network traffic, and next to good RSYNC packages there are also some bad ones named "Malformed RSYNC packet" in Wireshark. For example Sendi's Wireshark log looks like this: [Malformed Packet: RSYNC] Expert Info (Error/Malformed): Malformed Packet (Exception occurred) Message: Malformed Packet (Exception occurred) Severity level: Error Group: Malformed Since I'm no network expert (I can just start Wireshark and watch the many log entries), does anybody of you Cygwin users know what's happening? To sum up the problem: rsync worked well on Sendi & Desti, when suddenly a started rsync task just partly works but then stops. And depending on how many times I re-start the task or the computers, I can get smaller or bigger parts of the whole sync task. Usually not the entire however, because it stops long before the end...

Re: Copying HDD to another HDD
I don't know if this is what you are going to try, but if you change the of the partition on the src drive to something small enough to fit on the new drive, you can use clonezilla to clone the partition instead of the whole drive. Just make the partition on the new drive the same size or a bit larger. Just to be safe, I would copy off all the data files from the old drive that you can to a backup somewhere. You should be able to do the with a gparted CD. LMH Mike Brown wrote: On Sun, Nov 06, 2011 at 11:44:06PM +0800, KHMan wrote: Some random notes. fsarchiver also allows for flexibility on size.

Re: Copying HDD to another HDD
I think you want to use a disk clone to do this, something like the clonezilla live CD. As long as the drives are the same size, or the target drive is larger, clonezilla will just copy one drive to the other. It does a bit by bit clone, so it doesn't care about files and permissions and such. Even if you could copy with cp, you need the boot sector and such to get the OS up, so that wouldn't work.

Re: How do I run a program compiled in cygwin from a program that is running in a Windows CMD shell?
As stated, the mno-cygwin flag was depreciated in gcc 4. This was what you used to link to the windows c runtime instead of the cygwin dll. In other words, it let you compile with cygwin gcc and then run on a windows box that didn't have cygwin installed (very useful). Since some of your issue seemed to be with the cygwin environment, it seemed like detaching yourself from it at link time might be a good idea. Windows doesn't' know or care whether the app was compiled under gcc or visual studio if you used the no-cygwin flag, so I didn't see why it would matter how or where you called the app, from perl, bash, cmd, etc. I have never elevated to gcc 4 and have cygwin configured to only install gcc 3. I am sure you could have both installed and point to one or the other in your make file depending on what you want. If I remember right, the no-cygwin flag was depreciated before the "ming compatible cross compiler" was available, so I stayed with 3 at the time. I also had issues with 4.1 under linux. I had an app would give different floating point answers compiled wiht 4.1 compared to 3.4. This seems to have been fixed by 4.3 and the app compiled under 4.3 gives me the same answer as 3.4. I don't know if there was a bug in the early 4 versions, or what. This may have been an issue with gfortran and not gcc since it's a hybrid app. I also like the fact that 3 is closed and they aren't constantly changing the header files and such. It's very annoying to get code that compiled under an older version and won't compile any more because they changed 10 different header files and no I have to add 56 ifdef statements to compile under the new version. Version 3.4 does everything I need, so I have stuck with it, especially since I know how to cross compile with it. I suppose I will get around to getting version 4 working, but I have other fish in the pan for now. It seems like a cross compiled c app to launch your child process would be more portable, but I will look at the perl more closely later. I'm off to the dentist for now, fun, fun, fun.

Right. '-mno-cygwin' is not a supported flag for gcc with version 4. It was there to allow a kind of cross compiler that targets Win32 instead of Cygwin. This is obviously not what you want anyway so it's of no consequence to you that the flag has been removed. There are now actual cross compilers available in Cygwin for gcc 4 that serve the purpose of the old '-mno-cygwin' flag. Hi Larry, Thanks I installed only the gcc4 compilers (all of them, v4.5.3), but I didn't even look for cross compilers. What is the name of the cross compilers (would they be those that include 'mingw' in the name? Not having installed, them, perhaps this is a naive question, but will they live alongside the gcc4 compilers without the names of the compilers clashing?

Re: How do I run a program compiled in cygwin from a program that is running in a Windows CMD shell?
I am a bit confused as to the role of perl here. I have compiled under cygwin g++ for a long time now and don't run into problems. Are you using the -mno-cygwin flag in your compile rules? I have two processes, where one is a child of the the processed that gets launched, but both are in c. Maybe it is better to address your issue in the c part of the application, possibly create a little c launcher app that will create the behavior you need. Whether you run your c widget from win cmd, bash, call if from perl python, etc, shouldn't really make any difference. Maybe I need to dig into your post a bit more.

What value does the /usr part of the path have in this context? I suppose I should use force, but I never have anything running when I run the backup script that this is part of.

Re: Best way to repair cygwin?
You can select "re-install" in the package manager. Just toggel the icon next to "All" (at the top) until it reads "re-install". I like to keep a back up of anything I have added or configured, such as the path folders and such. That way, if I have to wipe out the cygwin folder and start again, it is not so much trouble. I would be nice if the package manager could dump it's current state to an xml file or something like that so I don't have to remember everything I have installed. Maybe there is a feature like that, but I'm not aware of it. I don't know if re-install keeps your configurations or not, so that is something to find out about or prepare for.

I had run setup again yesterday evening, in order to install wcd (found in the util section). The setup run to the end without error message, and I switched off the PC. Today I found bash broken. Since wcd utility is an extension to the chdir command, it is conceivable that it fiddled around with bash somehow, but I consider it unlikely that this would cause the effect I am observing: Such an obvious bug would not have been unnoticed. I wonder whether there is an easy way to "repair" Cygwin (maybe a procedure to automatically re-install everything). I searched on the Net but didn't find anything in this direction. Any other idea what I could do?

Re: install on win7 enterprise, can't modify bash start up shortcut
Well key shortcut copy and past would be very nice. How do I go about setting up bash to run with the mintty terminal and not cmd? Can you link me to something?

Re: install on win7 enterprise, can't modify bash start up shortcut
Thank you for all the clarification on shells and terminals, I have always used the terms interchangeably, which I guess was not correct. A few replies, > Is there any religious taboo that would prevent you from opening the > batch script in an editor and see that you're wrong? No, I did this on my XP cygwin install, and there is clearly nothing there to indicate the windows size, nor was there anything in the bashrc files, so I didn't know where to look next. I suppose I need to look at ini files for the terminal that gets started. > That window belongs to cmd.exe; bash runs inside it. The settings are > in the registry; for the Cygwin shortcut it's This would imply that I'm trying to change a registry setting related to cmd.exe and the OS isn't letting me. The confusing thing is that I have done this before on the exact same OS and not had this issue. Just for giggles, I tried to change the terminal settings for my windows command line shortcut. I did not get the same error, but I did notice that there was a menu entry called "Defaults" as well as "Properties". This gives the same options, but this time when I save them there is no error. Changing the defaults changes the window options for both the bash shortcut and the windows cmd shortcut (I have both on my desktop). So I guess this is resolved, but I suppose I should look in to running the mintty terminal. What are the basic advantages of this compared to running in cmd?

The shortcut points to cygwin.bat; Windows runs cmd.exe to interpret the batch file, which eventually starts bash. The desktop icon points to Cygwin.bat, but that doesn't have anything in it about the bash shell. Can someone point me to the ini file where the specs of the bash window would be recorded? That window belongs to cmd.exe; No, not really. Cmd is a shell, like bash. Up to Windows Vista and Server 2008, the console itself was implemented as just a bunch of library functions and a shared core in the csrss process. Start bash from Explorer, and in Task Manager you will see that no cmd is running. Starting with Windows 7 and Server 2008 R2, the console window is implemented as a standalone application called conhost.exe. So, if you start bash from explorer in W7, you will not only see bash, but also an additional conhost process. So, in a way conhost is the same as mintty, a terminal emulator, even if not a good one. Either way, that's a common misunderstanding of the way the Windows console works. It was never cmd. Cmd is and always was only a shell, just another console application like bash. I hope it goes without saying why you see a cmd process in task manager when you started bash via the Cygwin.bat batch file...

Re: install on win7 enterprise, can't modify bash start up shortcut
I've had no issue with re-sizing the bash window in the past and having those changes saved to the shortcut, even on win7 ent, so I am concerned about the health of the install. The desktop icon points to Cygwin.bat, but that doesn't have anything in it about the bash shell. Can someone point me to the ini file where the specs of the bash window would be recorded? I can check that file on another machine and see if it exists on the suspect install and see if I can edit it. That may give a clue as to what is amiss. I don't know anything about mintty and have always used bash. Can I run all of my bash commands, or would I be learning a new shell?

Using mintty would allow you to side-step the problem of not being able to modify the command prompt. For one thing, mintty can be resized :) Csaba -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
Re: install on win7 enterprise, can't modify bash start up shortcut
Sorry, I didn't reply correctly when I first tired to send this. This was simply modifying the shortcut that starts the bash window. If you double click on the Cygwin icon on the desktop, it starts a bash shell. If you click on the small Cygwin icon, upper left on the top window bar, you can select properties. This gives you a window to modify properties of the bash shell window such as the size, font color, font size, etc. When you close after your modifications, there was always an option to apply the changes to the current window only, or to modify the shortcut that started the window. I have always done this as soon as I installed cygwin. This time, I got the aforementioned error message. I am not sure what to do to allow me to modify the bash window on a permanent basis. If the shortcut isn't there, that would imply that the install may not have gone correctly, but I have installed two or three times (in different locations), trying to correct this, but the results are the same. I have had other issues with win 7 where software could not write to files in their own install directories. This seems especially prevalent with apps that don't make registry entries. I was wondering if something similar was in play. The cygwin icon points to Cygwin.bat, so I presume there are some arguments in the script that configure the shell. I could try to manually edit the .bat, but I'm not sure what I would change to get the window modifications I am looking for.

If it points to a non-existing target than delete it and re-create manually. Or run setup again which should do the same.

install on win7 enterprise, can't modify bash start up shortcut
I have just installed 1.7 on win7 enterprise 64 bit and I tried to modify the shortcut that starts the bash window and I get a windows error message, "can't modify the shortcut . make sure it has not been deleted or renamed" I currently have cygwin installed at E:/cygwin and I also tried "reinstall using the recommended windows settings", as well as installing at C:/cygwin. I get the same error every time. I have installed on this OS before and I don't remember this issue, so I'm not sure what is going on. Do I need to change permissions on the cygwin folder, the cygwin installer, change windows permissions, install it in a different location, etc? I have had non-windows programs on the C drive not be able to write to their log files and such,!@#*&^%&, but this was always correctable by installing elsewhere. I have also done, mkpasswd -l > /etc/passwd and mkgroup -l > /etc/group if that matters to anyone. This was also an offline install, which I have never had any issue with before.
