Re: Simple patch to enable stereo visuals in XWin_GL
On Fri, 20 Jul 2007, DRC wrote: Hi. I was wondering who maintains the experimental accelerated GLX support in Cygwin/X. I have a simple patch which enables stereo visuals (necessary to support my project, VirtualGL) on systems that support stereo. I'd like to get this patch incorporated into the Cygwin distribution of XWin_GL, if possible. Darrell, Cygwin/X is basically the X.org tree built for Cygwin. So you can try sending your patch to the upstream X.org team. However, we are currently missing a maintainer for Cygwin/X. So there probably won't be a new release of Cygwin/X to pick up the fix, even if it's accepted into the upstream tree. Volunteer maintainers welcome.

I was looking for feedback on whether this is of enough general interest that I should spiff it up and turn it into a CygWin package. I believe most of the menu items are self-explanatory; but they introduce people new (or not so new) to CygWin to how cygstart(1), dialog(1), XNest(1) and other utilities can be integrated with CygWin/X11 features too often overlooked to create a very complete user environment. You should certainly feel free to propose a Cygwin package with your modifications (as long as it does not overwrite existing configuration). See http://cygwin.com/setup.html for instructions on packaging for Cygwin. Since you are already providing a web site with this information, you can also add a setup configuration (setup.ini and directory structure) to allow people to install and test your package directly off your site by adding it as a mirror in Cygwin setup. Another option is to try integrating it with the X-startup-scripts and X-start-menu-icons packages, though I don't recall who maintains them, and whether they are as maintainer-less as Cygwin/X itself.

is LD_PRELOAD available in cygwin?
[EMAIL PROTECTED] using google i found only a few post's about LD_PRELOAD in cygwin concerning patches. Now i'm not sure if the linux-like LD_PRELOAD feature is available in cygwin. What i try to do: using g++ to compile a dll which overload's the open(); glibc system call. Using preload i want to load my own dll with my open(); function. using dlsym(); i try to load the glibc open(); function. On a suse box it works great, but cygwin seems to ignore LD_PRELOAD. the commands i use: g++ -g -c -Wall test.cpp g++ -shared -o libtest.dll test.o -ldl LD_PRELOAD=./libtest.dll somecommandwhichusesopensyscall Q1: is LD_PRELOAD available in cygwin? if yes, any hint's why it's not working? (maybe some configuration problem or so, any hint would be helpfull) Q2: are there any alternative ways to preloading causing the same result?

Any help or suggestion is very welcome.

Request for running a test application
Hi,
I have a request for help. I need as much different information I can
get. To get this information, I'm asking all of you to run the attached
test application and return the printed output as reply to this mail.
Just please don't send information which is already available.
The test application is a rewritten version of the GetVolInfo source
code which I have already send once or twice. A bit of information has
been added and that's what I'm especially interested in.
To build the application call:
gcc -o getvolinfo getvolinfo.c -lntdll
To run the application, simply call it with a POSIX or DOS path to any
existing file on a filesystem, which you have permissions to access.
The simplest method is to access the drives directly. For instance, if
you have a drive c and a drive d, just call
./getvolinfo C:
./getvolinfo D:
Please run it on all file system combinations you can lay your hands on.
So far, I have information about:
- Local FAT, FAT32, NTFS
- Local CD, DVD
- Remote NTFS
- Remote Samba 3.x
- USB Stick with FAT, NTFS
I'm looking for
- Harddisk, CD, DVD over USB
- Remote FAT, FAT32
- Remote CD, DVD
- Remote NFS over SFU NFS
- Local(?) and remote HPFS
- Disk changer systems
- Any other file system not mentioned above.
Thanks in advance,
Corinna

Re: SSHD install problem
Thorsten, Thank you very much for trying to help me, I appreciate it. I have tried many different things to get this working including erasing my old cygwin folder and reinstalling cygwin. The instruction you supplied executes without error, but when I try to start the sshd service, it still will not start and looking in the /var/log/sshd.log file, I still see the same error message. Could my problems be caused because I am a Windows domain user? When I ran bash the first time after reinstalling, it said I needed to run a command and redirect its output to /etc/passwd and another command redirected to /etc/group After doing that I looked in those files and I noticed there were hundreds of users listed, practically everyone from the domain I think. I ended up erasing most of the lines, leaving my user, the sshd user, SYSTEM, Administrators and Administrator in the passwd file, and not touching the group file... Maybe I messed up... Any help is appreciated, thanks.

tcsh 6.15.00 TZ environmental variable - unexpected behaviour.
It appears that tcsh treats the TZ environmental variable in a special way - upon entry into tcsh, some commands see TZ as set. Using unsetenv to attempt to unset it is fruitless: bash-3.2$ unset TZ bash-3.2$ printenv TZ bash-3.2$ echo $TZ bash-3.2$ bash -c printenv TZ bash-3.2$ tcsh tcsh$ printenv TZ tcsh$ echo $TZ GMTST0GMTDT-1,M3.5.0/1,M10.5.0/2 tcsh$ bash -c printenv TZ GMTST0GMTDT-1,M3.5.0/1,M10.5.0/2 tcsh$ unsetenv TZ tcsh$ printenv TZ tcsh$ echo $TZ GMTST0GMTDT-1,M3.5.0/1,M10.5.0/2 tcsh$ bash -c printenv TZ GMTST0GMTDT-1,M3.5.0/1,M10.5.0/2 Unfortunately our application requires TZ to be unset to function correctly (see below for why). Can anyone give me a pointer as to how to ensure TZ is unset in tcsh? I have googled for cygwin tcsh TZ and searched the Cygwin mailing list for tcsh TZ, but have been unable to find any relevant threads. I also looked briefly at the source for tcsh. From my investigations, it appears that tcsh has various features related to time; the time of execution of each command line is held in the history, and there is also the facility to print the time in the prompt. As part of these facilities, tcsh calls Cygwin functions such as ctime(), gettimeofday() and localtime(), which call tzset(). tzset() sets the TZ environmental variable if it is not currently set. This is then visible in the environment used for some commands. Why don't I simply get rid of the tcsh monstrosity and use a sensible shell instead? An excellent idea and my personal preference. Unfortunately this would require considerable effort and thus the buy-in of my superiors, which is not currently forthcoming. Additionally, the use of tcsh as an interactive shell would need to be forbidden, which would be unpopular and difficult to enforce both internally and with clients. Why can't I just set TZ to the required value? Our application uses both Cygwin binaries and binaries compiled using MSVC from tcsh. There is no value for TZ that will produce correct time and date information for both categories of binaries for all times of the year for timezones outside the US that use DST. This is because the MSVC implementation of tzset() assumes that daylight savings time is always one hour, and starts and ends on the dates and times that happen to prevail in the US at the time MSVC was written.

Stack traces in own program in cygwin
Hi, I'm working on some unit testing framework and was thinking of building in some functionality for stack traces. I checked what functionality is available and found glibc contains execinfo.h with backtrace which can be used (for linux). For Windows, I use gcc and cygwin. I cannot find the execlib.h in cygwin at all, so I'll need to find a different way. In Windows I can probably use the MS dbghelp.dll, but that would create a dependency on Win SDK, which I prefer not having. Does anyone have any idea about this, or is (or will) execinfo.h be available? Any other way of doing it without Win SDK?

Launching TightVNC over ssh using cygwin
I'm using TightVNC on a remote windows machine for maintenance purposes, communicating via an ssh tunnel (sshd installed using cygwin). Everything works when I start TightVNC as a Windows service, but I'd like to leave TightVNC turned completely off, and only launch it when I need it. To do that I need to be able to launch it from an ssh command line. I can ssh in and use cygstart to launch TightVNC, but then when I try to connect to TightVNC the connection is refused. Here's the TightVNC log (first four lines is when I launched TightVNC; rest is my attempted connection): Wed Aug 01 08:09:54 2007 vncServer.cpp: trying port number 5900 Wed Aug 01 08:09:55 2007 vncSockConnect.cpp: started socket connection thread Wed Aug 01 08:10:09 2007 vncSockConnect.cpp: accepted connection from 127.0.0.1 vncClient.cpp: client connected : 127.0.0.1 (id 1) vncClient.cpp: performing VNC authentication WallpaperUtils.cpp: KillActiveDesktop vncService.cpp: unable to open desktop, error=1 vncService.cpp: SelectHDESK failed to close old desktop 24, error=170 vncServer.cpp: failed to initialize desktop object No, there's no other copy of TightVNC running.

Using preload i want to load my own dll with my open(); function. using dlsym(); i try to load the glibc open(); function. Cygwin does not use glibc. glibc is Linux-specifc. Q1: is LD_PRELOAD available in cygwin? if yes, any hint's why it's not working? (maybe some configuration problem or so, any hint would be helpfull) Q2: are there any alternative ways to preloading causing the same result? No, LD_PRELOAD is an aspect of ELF dynamic loaders and is not available on Windows. It's not something that Cygwin can provide since it is a function provided by the program loader, i.e. the operating system. If you have source of the target program and can modify it, then you can dlopen() the DLL and use dlsym() to get a function pointer to the replacement open() function, and then use that function pointer instead of the libcall throughout. But if you want this to be transparent, i.e. without modifying or recompiling the target, then you'll have to use some kind of low-level Windows-specific hackery because this is not a feature the PE loader has. http://research.microsoft.com/sn/detours/ http://www.internals.com/articles/apispy/apispy.htm Brian -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

We've got a pdksh.exe process that is spinning, using all the CPU. This scenario is very hard to reproduce, but has happened on our test systems occasionally. It occurred recently, and I currently have gdb attached to the process and have the symbols loaded. I assume you've rebuilt pdksh from source, since the packaged binary is stripped... Do you also have the symbols for the Cygwin DLL? Yes, I've built both pdksh and cygwin1.dll from source and have the symbols. Ok, great. I see that pdksh is continually calling sigsuspend(), which is immediately returning from cancelable_wait due to the fact that the signal_arrived event is set. Do you mean the sigpause() call? Can you see which signal it attempts to suspend? Can you email me (privately, if you wish) the stack dump from gdb? It's sigsuspend() in j_waitj - line 1191 in jobs.c. It calls sigsuspend(sm_default), and sm_default is 0 (no signals are blocked). This immediately returns, and I see that j-state is still PRUNNING every time. Hmm. That should be fine -- since it does not know the job terminated, the status reflects pdksh's current knowledge. And since sm_default is 0, sigsuspend ought to be the no-op it is. I also see that pdksh is waiting for a subprocess to complete, and has a handle to the PID of that process - however the process has long since terminated. That's normal (I think). Cygwin may not deliver SIGCHLD immediately after process termination. Until pdksh gets SIGCHLD, it'll keep the process handle. It appears that something went wrong during delivery of SIGCHLD. Does this happen before or after j_sigchld() gets invoked? I suspect that j_sigchld never got invoked, or didn't run properly, but can't definitvely prove that. It's set as a handler for SIGCHLD. If your theory is correct, and SIGCHLD delivery is interrupted, then it won't have executed. I've got two questions related to this: - have there been changes between 1.5.20-1 and 1.5.24-2, or the latest snapshot, that might have fixed this issue? We've done some limited testing with 1.5.24-2 and haven't seen this happen yet, but as I said the it only happens rarely. Quite possibly. There were changes to signal handling since 1.5.20, IIRC. Unless I'm mistaken, there's even a patch for a race condition in process handling code (though it's not in 1.5.24, I think). - is there anything I can look at in gdb to help identify what the issue is? Any suggestions would be appreciated! Posting a sequence of steps that reliably reproduces the problem for you would be great (but not necessarily easy). I wish I could supply this, but the problem happens very rarely. I've run many thousands of test shell iterations and haven't seen it reoccur yet. Right, which is why it's not necessarily easy. :-) As I said above, a stack dump (with full pdksh symbols) would help... That might mean that you'd need to build an unstripped pdksh and attempt to reproduce the problem again. Igor Here's a stack trace of the thread where the spin is occurring. The other threads in the process are quiet - the signal thread is is ReadFile as expected, and the other threads are all in stub routines doing WaitForSingleObject.

Re: Stack traces in own program in cygwin
Bas Vodde wrote: I'm working on some unit testing framework and was thinking of building in some functionality for stack traces. I checked what functionality is available and found glibc contains execinfo.h with backtrace which can be used (for linux). Yes, that's glibc-specific functionality which is not applicable elsewhere. For Windows, I use gcc and cygwin. I cannot find the execlib.h in cygwin at all, so I'll need to find a different way. In Windows I can probably use the MS dbghelp.dll, but that would create a dependency on Win SDK, which I prefer not having. There is rudimentary code in Cygwin for trying to unwind the stack, but it's only used in fatal error conditions such as when a SEGV fault occurs and the foo.exe.stackdump file is written. And this just shows the raw memory addresses of the call chain, it does not attempt to resolve them into symbolic functions, so it would be quite useless for a user. It is possible to write code that uses the dbghelp library that does not need anything third party tools installed, as the library is included as part of the operating system since Win2k. However, the bundled version may be quite old, so it might not have all the functionality of a newer one. See e.g. http://msdn2.microsoft.com/en-us/library/ms679294.aspx You could also bundle a copy of gdb, and then attach-backtrace-detach, but that's probably not the kind of answer you're looking for.

Re: New rename(2) function
Corinna wrote:
[Bah - gmane can't post to cygwin-devel, so I'm cross-posting (in order to
reply now, rather than waiting till when I'm home).]
Also, where do you check that rename(a,a) is a successful no-op, as
well as rename(a,b) when a and b are hard links to the same inode
(perhaps both of these cases are covered by NtSetInformationFile?)
rename (a, a) is a no-op because NtSetInformationFile will just
return with status 0, doing nothing.
I don't see anything about rename(a,b) with both hardlinks to the
same inode being a no-op. Neither in Linux, nor in SUSv3, nor in IEEE
P1003.1 Draft 3. Actually, rename(a,b) will rename a to b, thus
decreasing the link count of the file by 1, on Linux as well as on
Cygwin.
Huh? SUSv3 states this:
If the old argument and the new argument resolve to the same existing file,
rename() shall return successfully and perform no other action.
Note that the requirement is careful to mention resolving to the same file (and
not merely the same string for the two names, or even the same directory entry
possibly via different symlink paths).
And on Linux, I get this:
$ cat rename.c
#include stdio.h
#include errno.h
int main(int argc, char** argv)
{
if (argc 3)
{
puts(Usage: rename old new);
return 1;
}
int res = rename(argv[1], argv[2]);
snprintf(buf, sizeof(buf), result %d, errno %d, res, errno);
perror(buf);
return 0;
}
$ touch l1
$ ln l1 l2
$ ./rename l1 l2
result 0, errno 0: Success
$ ls -l l?
-rw-r--r-- 2 ericb cygwin 0 Aug 1 14:48 l1
-rw-r--r-- 2 ericb cygwin 0 Aug 1 14:48 l2
ie. a pure rename was a nop, rather than unlinking l1. Note, however, that mv
(1) from coreutils will indeed unlink l1 and reduce the link count of l2.
Indeed, there are a number of posts related to this issue in both coreutils and
Austin:
https://www.opengroup.org/sophocles/show_archive.tpl?source=Llistname=austin-
group-lfirst=1pagesize=80searchstring=renamezone=G
https://www.opengroup.org/sophocles/show_mail.tpl?
CALLER=show_archive.tplsource=Llistname=austin-group-lid=5156
http://lists.gnu.org/archive/html/bug-coreutils/2003-04/msg00042.html
And XSH ERN 88 (which proposed rewording POSIX with s/same existing file/same
existing directory entry) was rejected.
It looks like draft 3 of POSIX 200x hasn't touched this area yet, so I'll raise
the issue again on the austin lists on the mv(1) side of things. But it looks
like cygwin's rename(2) will need to take this POSIX rule into account, to
match linux.

RE: cygwin 1.5.20-1, spinning pdksh, 100% CPU
-Original Message- From: Igor Peshansky On Tue, 31 Jul 2007, Ernie Coskrey wrote: I've run into a problem with cygwin 1.5.20-1 and pdksh 5.2.14. We've got a pdksh.exe process that is spinning, using all the CPU. This scenario is very hard to reproduce, but has happened on our test systems occasionally. It occurred recently, and I currently have gdb attached to the process and have the symbols loaded. I assume you've rebuilt pdksh from source, since the packaged binary is stripped... Do you also have the symbols for the Cygwin DLL? Yes, I've built both pdksh and cygwin1.dll from source and have the symbols. I see that pdksh is continually calling sigsuspend(), which is immediately returning from cancelable_wait due to the fact that the signal_arrived event is set. Do you mean the sigpause() call? Can you see which signal it attempts to suspend? Can you email me (privately, if you wish) the stack dump from gdb? It's sigsuspend() in j_waitj - line 1191 in jobs.c. It calls sigsuspend(sm_default), and sm_default is 0 (no signals are blocked). This immediately returns, and I see that j-state is still PRUNNING every time. I also see that pdksh is waiting for a subprocess to complete, and has a handle to the PID of that process - however the process has long since terminated. That's normal (I think). Cygwin may not deliver SIGCHLD immediately after process termination. Until pdksh gets SIGCHLD, it'll keep the process handle. It appears that something went wrong during delivery of SIGCHLD. Does this happen before or after j_sigchld() gets invoked? I suspect that j_sigchld never got invoked, or didn't run properly, but can't definitvely prove that. I've got two questions related to this: - have there been changes between 1.5.20-1 and 1.5.24-2, or the latest snapshot, that might have fixed this issue? We've done some limited testing with 1.5.24-2 and haven't seen this happen yet, but as I said the it only happens rarely. Quite possibly. There were changes to signal handling since 1.5.20, IIRC. Unless I'm mistaken, there's even a patch for a race condition in process handling code (though it's not in 1.5.24, I think). - is there anything I can look at in gdb to help identify what the issue is? Any suggestions would be appreciated! Posting a sequence of steps that reliably reproduces the problem for you would be great (but not necessarily easy). I wish I could supply this, but the problem happens very rarely. I've run many thousands of test shell iterations and haven't seen it reoccur yet. As I said above, a stack dump (with full pdksh symbols) would help... That might mean that you'd need to build an unstripped pdksh and attempt to reproduce the problem again.

The Solution to Ctrl-C problems
This isn't exactly a cygwin fix, but this is what worked for my problem. I needed a consoleapp launcher to start up when the machine starts. Then I use ssh to give consolelauncher arguments of what console app to launch Then I use ssh to launch another program I wrote in C# which uses AttachConsole and GenerateCtrlCEvent to send a CtrlC to the desired console. From there I control the console with stdin and stdout redirection as one would expect.

printf
Hello guys,
I came across this page comparing different implementations of printf.
http://www.and.org/vstr/printf_comparison
The author says...
Note that if you want a portable version of printf() in your code, you
are _much_ better off using something that natively parses the format
string. This ensures that you get the same parsing behavior on all
platforms
If in cygwin, I have a c file like so...
#include stdio.h
#include stdlib.h
int main(int argc, char* argv[]){
printf(Which printf am I using?\n);
}
... and I compile it under cygwin with gcc -mno-cygwin test.c...
Would I be using one that natively parses the format string?
... now if I compile without the -mno-cygwin option, what happens?
I was looking around in some gcc source code for printf and found
vprintf.c which calls vfprintf.c with stdout, which calls _doprnt.
All of these were in a directory called libiberty. Furthermore, the
_doprnt winds up calling fprintf.
Does GCC have it's own implementation of printf and is it different than
glibc's implementation?
As you can tell, I don't understand much about this. Why would both gcc
and glibc have a printf implementation? Any help is appreciated.
I am also looking into this because I wanted to create my own
specialized version of printf which prints to two files with just one
function call. I would be doing some different things on each file. I
was looking for a good vfprintf to start with.
Thanks,
~Eric

I don't know what exactly this is trying to say, but my interpretation
of it is you need to write your own %-format parsing code if you need
to be sure of how it's going to behave which IMO is quite a silly thing
to say. It's a tautology, you can't really be sure of X unless you do
it yourself. But if you're just using simple and standard format
specifiers (like %s and %d) it would be needlessly ridiculous to
implement your own.
If in cygwin, I have a c file like so...
#include stdio.h
#include stdlib.h

By my interpretation, neither, since natively parses the format string
means you wrote the code that does the parsing, whereas here you are
just calling the C library's printf to do it.
Note that you are using two different C libraries above, Cygwin and
MinGW (MSVCRT).
I was looking around in some gcc source code for printf and found
vprintf.c which calls vfprintf.c with stdout, which calls _doprnt.
All of these were in a directory called libiberty. Furthermore, the
_doprnt winds up calling fprintf.
Does GCC have it's own implementation of printf and is it different than
glibc's implementation?
There are at least three things wrong in the above paragraphs.
1. gcc does not implement a C library, so there is no implementation of
any printf in gcc. The C library is separate from gcc, gcc is just the
compiler.
2. libiberty is only a portabilty library. It does not implement any
actual printf code (it just calls the C library's fprintf as you
discovered.)
3. glibc is only used on linux. On Cygwin and MinGW you are not using
glibc.
I am also looking into this because I wanted to create my own
specialized version of printf which prints to two files with just one
function call. I would be doing some different things on each file. I
was looking for a good vfprintf to start with.
It depends on what these different things actually means. You can do
a lot with the varargs version of printf, e.g.:
int my_special_snowflake_printf (FILE *f1, FILE *f2, char *fmt, ...)
{
va_list ap;
va_start (ap, fmt);
fputs (header for f1 output: , f1);
vfprintf (f1, fmt, ap);
fputs (header for f2 output: , f2);
vfprintf (f2, fmt, ap);
va_end (ap);
}
I'd say it would be pretty silly do reimplement all of the actual printf
guts just to do file multiplexing, but whatever. If you want to see the
underlying implementation of printf that Cygwin uses, look in newlib.
If you want to see the underlying implementation of printf that MinGW
uses, you need the source code to MSVCRT which I believe is only
available if you buy MS Visual Studio.

You might want to {re,}read the section in http://cygwin.com/problems.html
which talks about referring to a problem as the problem. I'll quote it
here:
# Do not assume that your problem is so trivial or so well known that
it does not require any details or background from you. Many (most?)
people who report problems fall into the trap of assuming that people
are clued into their mental state when, in most cases, this is not
the case.
As a rule of thumb, if you find yourself referring to your problem as
the problem with XYZ rather than a problem with XYZ then your message
is suspect. Using the in this context means that you are assuming that
your problem is well known. Unless you can point to an email message
thread or FAQ entry (either of which is a good idea, btw) please do not
assume that the readers of your message will be familiar with your

Re: unlink()'s not quite POSIX behavior.
Joe Smith wrote: When the file's link count becomes 0 and no process has the file open, the space occupied by the file shall be freed and the file shall no longer Could we at least simulate the behavior by moving the file out of the way (simultaionsly renaming it to something unique), and forcing it into the delqueue? (by Setting the FILE_DISPOSITION_INFORMATION's DeleteFile flag to true?) Wait a moment, that looks to be exactly what unlink_nt is doing? (The problem is with a call in Python3k getting a Permission denied (ERRNO 13) error when attempting to create a file shortly after it has been deleted with unlink. That seems to be consistant with standard windows behavior for deleting a file, as trying to create it again before the last handle is closed would return an ERROR_ACCESS_DENIED.) However, it looks like with unlink_nt that should not be happening, right? Nevermind. I see that the relavent changes to NT_unlink are just very recent, and the only problem is that the latest cygwin dll does not incldue those changes yet. - I seem to remember being told that changing the rename function to work in this, POSIX-compatible way, was impossible with cygwin's current fork implementation -- and that Cygwin would have to keep track of what files have been renamed (if any were DLL's) and propagate changes to child processes (after a fork call) so they could correctly pull in contents of old, replaced DLL's. Is this change to fork something that is being worked on? I.e. will we be able (at an application (setup.exe or cygperl replacing DLL's) level) to rename in-use DLL's and copy in new versions? I thought Eric indicated that this tracking would make an already slow process even slower(?) and wasn't worth it. (http://sourceware.org/ml/cygwin/2006-12/msg00906.html) Has this changed? Or, more accurately, is this about to change? Was it decided to go with the (seemingly) POSIX correct action to allow the rename-to-tmp+copy-in-new-DLL (Rtt+CinD) to work? Will Cygwin be keeping track of the old deleted (but still in-use via a cygwin open Filehandle) libraries to duplicate into new children processes? I seemed to remember feeling my hand slapped at suggesting we use Rtt+CinD as it wouldn't be practical to implement. Maybe the open-handle-deleted file idea isn't that expensive to implement afterall? (Despite it being a RPITA; hail emperor bill).

RE: printf
Brian Dessent Wrote: 1. gcc does not implement a C library, so there is no implementation of any printf in gcc. The C library is separate from gcc, gcc is just the compiler. 2. libiberty is only a portabilty library. It does not implement any actual printf code (it just calls the C library's fprintf as you discovered.) 3. glibc is only used on linux. On Cygwin and MinGW you are not using glibc. Do vfprintf statements compiled on Cygwin go through libiberty which then calls fprintf, or is there another vfprintf in whatever C library I'm linking against (either Cygwin's or Microsoft's)? I'd say it would be pretty silly do reimplement all of the actual printf guts just to do file multiplexing, but whatever. If you want to see the underlying implementation of printf that Cygwin uses, look in newlib. If you want to see the underlying implementation of printf that MinGW uses, you need the source code to MSVCRT which I believe is only available if you buy MS Visual Studio. What I'm planning on doing is having a library with a printf-like function where I can do... float radius = 1.0; mySpecialPrintf(f1,f2,The radius is %f %U\n,radius,in,mm); And the result would be that in one file you get The radius is 1.000 in And in the other you'd get... The radius is 25.40 mm Basically it would be just like printf except that it is printing to two files and that any floating point printing gets converted. So what I'd have to change is that %f eats 3 arguments, the number and two units. Then I'd call a unit conversion library. I'd also create a new format (not sure if capital U is taken already) to print the previously used units. Having this library would avoid me writing two fprintf statements and having to do all the converstion inside the main program. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
Re: missing declaration for floorl
Fred Hansen wrote:
The random nubers package in http://www.agner.org/random/ uses function
floorl. It is present in the cygwin g++ library
(/lib/gcc/i686-pc-cygwin/3.4.4/libstdc++.a), but is not declared in any of
the header files (cd /usr/include; grep -rI floorl). If I declare it:
long double floorl(long double x);
then I can call it, link it, and get the correct result.
Should math.h be augmented with the declaration of floorl?
No. It's not a mistake that the definition is missing from math.h,
because Cygwin does not provide this function. libstdc++ is the C++
standard library, and in general it does not implement basic libc
functions like floorl, it relies on the target's C library
implementation for those. And in fact the floorl that is in libstdc++
is not a real implementation of floorl, it's just a stub:
#ifndef HAVE_FLOORL
long double
floorl(long double x)
{
return floor((double) x);
}
#endif
The comment at the top of this file (libmath/stubs.c) even says:
/* For targets which do not have support for long double versions,
we use the crude approximation. We'll do better later. */
So it's clear that these functions are only provided as a last resort,
and they aren't even fully correct implementations either since they
just cast away the extra bits.
And even if you added a prototype to math.h for this crude floorl(),
linking would still fail on plain C source using the gcc driver, because
you do not link with libstdc++ unless you use g++. So it would still be
a broken implementation, but even more confusingly broken since it would
appear to support something that it doesn't.
No, the real problem is not that there are missing prototypes, it's that
actual long double support is missing.

Re: Stack traces in own program in cygwin
Hi Brian, Thanks for the reply. Where can I find the cygwin code that unwinds the stack? I might have a look at it anyway :) The problem I have with dbghelp is not whether the DLL is available, but whether the WinSDK is... It would require a header file (which is possible to fake) and a .lib. I'm not sure how to call the dbghelp calls without linking to the library. (though this should be possible, I just don't know how and where to find info about how to do it). If you for an idea about this, then that also could help me forward :) Thanks! Bas Brian Dessent wrote: Bas Vodde wrote: I'm working on some unit testing framework and was thinking of building in some functionality for stack traces. I checked what functionality is available and found glibc contains execinfo.h with backtrace which can be used (for linux). Yes, that's glibc-specific functionality which is not applicable elsewhere. For Windows, I use gcc and cygwin. I cannot find the execlib.h in cygwin at all, so I'll need to find a different way. In Windows I can probably use the MS dbghelp.dll, but that would create a dependency on Win SDK, which I prefer not having. There is rudimentary code in Cygwin for trying to unwind the stack, but it's only used in fatal error conditions such as when a SEGV fault occurs and the foo.exe.stackdump file is written. And this just shows the raw memory addresses of the call chain, it does not attempt to resolve them into symbolic functions, so it would be quite useless for a user. It is possible to write code that uses the dbghelp library that does not need anything third party tools installed, as the library is included as part of the operating system since Win2k. However, the bundled version may be quite old, so it might not have all the functionality of a newer one. See e.g. http://msdn2.microsoft.com/en-us/library/ms679294.aspx You could also bundle a copy of gdb, and then attach-backtrace-detach, but that's probably not the kind of answer you're looking for.

building lapack with cygwin
Hello, I tried to build Lapack 3.1.1 using cygwin. Compilation works fine, but testing reports failures. The g77 flags were -O3 -funroll-all-loops. For gcc 3.3.3 failures are reported by CEV, CVX, CGV, DGV, SGV, ZGV. For gcc 3.4.4 failures are reported by CGV, DGV, SGV, ZGV. As far as the prebuilt binary (lapack 3.0-5)is concerned, I tried to run the Lapack-3.0 tester against it. The result is: $ make blas_testing ( cd BLAS/TESTING; make -f Makeblat1 ) make[1]: Entering directory /home/Weronika/LAPACK/BLAS/TESTING' make[1]: Nothing to be done for all'. make[1]: Leaving directory /home/Weronika/LAPACK/BLAS/TESTING' ( cd BLAS; ./xblat1s sblat1.out; \ ./xblat1d dblat1.out; \ ./xblat1c cblat1.out; \ ./xblat1z zblat1.out ) 3656 [main] xblat1c 2808 _cygtls::handle_exceptions: Error while dumping state (probably corrupted stack) /bin/sh: line 3: 2808 Segmentation fault (core dumped) ./xblat1c cblat1.out 7 [main] xblat1z 3096 _cygtls::handle_exceptions: Error while dumping state (probably corrupted stack) /bin/sh: line 3: 3096 Segmentation fault (core dumped) ./xblat1z zblat1.out make: *** [blas_testing] Error 139 When lapack test is run, I get 8 [main] xeigtstc 3376 _cygtls::handle_exceptions: Error while dumping state (probably corrupted stack) 6 [main] xeigtstz 964 _cygtls::handle_exceptions: Error while dumping state (probably corrupted stack) Failures are reported by DGV, ZGV.

Re: Re: missing declaration for floorl
Aha. There is no floorl in cygwin. It is too bad that the stub function causes autoconf to believe there IS a floorl. AC_CHECK_FUNCS finds the stub and reports that the function is available.

Re: Stack traces in own program in cygwin
Bas Vodde wrote: Thanks for the reply. Where can I find the cygwin code that unwinds the stack? I might have a look at it anyway :) Look at class stack_info in winsup/cygwin/exceptions.cc. It's pretty simplistic, and I'm pretty sure it will be rendered totally ineffective by -fomit-frame-pointer.

If you for an idea about this, then that also could help me forward :) You can use LoadLibrary/GetProcAddress, which removes the need for the SDK and import lib/header at build time, assuming that you recreate the appropriate types in one of your headers. It also provides your program an opportunity to do graceful degredation if something goes wrong, e.g. the user is running 9x/ME, or they have a version of the dll that's too old, or the library has been removed, or whatever. The disadvantage here is that for every function you use you first have to declare a function pointer with the correct return type/signature/argument list, then call GetProcAddress, then make all calls through that function pointer. There is a clever trick that the Cygwin DLL uses that reduces this busywork -- look at autoload.cc for details.
