It happened to me when trying to install gAim; it tried to load the 
cygwin versions of DLLs with the same names as it was looking for, and 
crashed on startup. I think it is safest to keep cygwin out of your 
Windows PATH.
One frigging application out of how many? Easily fixed with merely a 
script like:


#!/bin/bash
# Start gaim with a limited path
PATH=""
exec /apps/gaim/gaim $@

Note that Cygwin supports the termios(3) interface but not the 
ioctl(2) interface for controlling serial ports.  Using termios(3) 
should allow you to use the same source on either Cygwin or Linux, 
at least for the serial port control.

Accessing RS-232 serial port under Cygwin

[ask . teddy]

Hello,

I want to write a C program which runs on a desktop computer and talks
to a device over the RS-232 serial port. I'm using WinXP + Cygwin, and
sometimes Ubuntu Linux. I hope this program can be ported to either OS
with the least modification at the source level. How can I use a C
program to access the serial port under Cygwin?

Many thanks.

It's the default configuration.

Which, it turns out is the problem.  Thanks for the hint.  Apparently, the 
created user (sshd_server) can't switch to SYSTEM at startup, but has no 
problems switching to other users after proftpd is already running.  So 
/etc/proftpd.conf needs to specify the same user that you give to 
cygrunsrv, or it won't start the service.

Yes, and it works fine under Win XP, so it must be something missing in your
user sshd_server privileges.

I observe a similar behaviour with a document of about 43 page.

The same thing happens using 'M-x compile' with a my application that
gives about 2000 line of link errors: emacs simply dies!


The problem doesn't occur with my cited build of emacs 22.1.


The following information might be helpful in investigating
this problem:

1. Provide a detailed list of the steps (Emacs commands)
   that you are running to reproduce the problem.  This
   should include a document file that is input into 
   Emacs, preferably included as an attachment to your

   message, and compressed using bzip2 or gzip.

2. Provide a detailed list of the steps that you took
   to create your emacs binaries.  This should include
   a copy of the output of 'configure' (again, included
   as a compressed text file attached to your message).
   Unfortunately, the Emacs documentation is opaque
   about what environment must be available during the
   configuration stage.

I, for one, will look at this information if you provide
it to help investigate what is causing the problem.  Others
might find it useful, too.  Once a solution has been found
it should be possible to include the proper steps in the
cygport for Emacs so that it can be used going forward with
later releases of Emacs.

Help needed to access cygwin sshd server (installed on windows) from remote client with putty under windows XP

[shiliang Wang]

From: shiliang Wang [mailto:[EMAIL PROTECTED] 
Sent: Thursday, July 26, 2007 4:52 PM
To: 'cygwin@cygwin.com'
Subject: Help needed to access cygwin sshd server (installed on windows)
from remote client with putty under windows XP 

Hi,
I am new here, I just wonder if someone can help me to access a remote sshd
server with a client machine installed with Putty?
The remote server I tested is in the same lab. Since many people in this lab
need to use this super computer, I try to install a cygwin sshd server on
the super computer to make it a server.
 A: I have already done this part. When I typed  “net start sshd”, it starts
and “ssh localhost”, it asked me the password. After I gave it password, it
said the connection has been established successfully.
  I followed the exact the step described by this link:
http://pigtail.net/LRP/printsrv/cygwin-sshd.html. It included these steps 
 mkpasswd   -cl   >   /etc/passwd 
 mkgroup   --local    >   /etc/group
 
B: I installed putty on another machine in the same lab, and tried to
accessed this super computer. I never succeed.
I inputted IP address of the super computer and keep all of the rest
parameters default.
It always said timeout. Never log on the server.

Both super computer and putty are installed under windows XP professional.

Any helps and suggestions will be greatly appreciated. Thanks in advance!

Shiliang

proftpd as a service under 2003

[Chris Stromsoe]

I'm having trouble getting proftpd to run as a service under 2003.  I read 
/usr/share/doc/Cyginw/openssh.README.  I used ssh-host-config to create an 
account named sshd_server.  I have ssh running fine.


If I try to use the same account, I get the error

  Error starting a service: QueryServiceStatus:  win32 error 1062:
  The service has not been started.

Looking in the logs, I have:

  unable to set uid to 18, current uid: 1006

Running /usr/sbin/proftpd from the command line gives me the same error, 
except the current uid is 500.


The system is windows 2003 server.  cygwin is 1.5.24.

Any ideas?



-Chris

The messages you are receiving ("No Remote Directory.", "Permission denied.")
point out a problem with the user's HOME directory.

It would be better if you specify the steps you used for testing:

- Did you create /etc/passwd and /etc/group on the server;
- Are they local users or domain users;
- Have you tried rlogin?
- Do you get the server's welcome message and prompt for a passwd (if not then
check `which rsh` you are using -- Windows has it's own rsh command).

  rsh is an inherently unsecure protocol.  Don't use it.  Don't use
  the excuse that this is on a local corporate network only.  You
  have no idea who's sniffing on your network.  Better use a secure
  protocol instead, like ssh.  All services provided by the OBSOLETE
  rsh/rlogin/telnet interfaces are provided in a much more secure
  way by ssh.

Have U tried untarring it through a pipe?  U could get a listing (tar
-ztvf ...) and store it in an array, then loop on the array and pipe
each file through a pipe and a filter (tar -zOxvf arch.tar.gz
[ArrayElement] > [modifiedArrayElement]).  I don't recall bash array

working without much trouble.  As U note, the names are clunky, but
it's better than nothing.

Note that changing perl to use long doubles is a binary incompatible change.
So if anyone is going to jump on this, it would be nice to have it happen
before the already incompatible 5.10 is out Septemberish.

modfl isn't strictly necessary; perl will substitute aintl (a solaris

And ilogbl + scalbnl can be used to emulate frexpl.

That happens if you have a symlink and a directory of the same name.
The stat buffer will for both of them return the data for the first one,
usually the directory.  That's the price of using Windows shortcuts
as symlinks.

I've had good luck with the c9x-complex package:

Of course, you should test carefully yourself, but for me this provides

But you can't.  That command should fail on Cygwin.

libc is the generic name for the C standard library of functions.  It
has to come from somewhere; it's not part of gcc.  On Linux it is
typically the GNU libc (glibc), though on embedded Linux it might be
something else such as uclibc or dietlibc or newlib or ...  On Cygwin,
the libc functionality is provided by the Cygwin DLL, which internally
uses newlib to implement substantial portions (such as the stdio and
math related functions.)  On MinGW the libc is the Microsoft C library,
MSVCRT.DLL.

Again, note that this is totally independent of the compiler.  gcc runs
on all three of those systems but gcc is just a compiler, *not* a C
library.  It uses whatever the system provides.  Now gcc may provide
built-in replacements of some standard C library functions which it uses
when inlining -- for example it might know that it can replace a call to
the library function memcpy() with a simple direct assembly copy loop. 
But there always must be a library copy of the function backing these
builtins, they are only suppliments.

Thing these are three separate platforms, so don't expect them to behave
the same.  
glibc most definitely provides all those functions.  If you blindly grep
for them in header files you may not find them as glibc uses a twisty
maze of macros to implement headers.  Instead of blindly grepping around
in the dark though, use the manual.  There is a nice index that shows
precisely what the library supports:
.

On MinGW, most of those C99 math functions don't exist in MSVCRT.DLL so
there is the mingwex helper library that implements them.

> If I call sqrtl on linux I have to link to -lm, on Cygwin I don't.

This is just a bit of historical trivia.  Back before shared libraries
were common and everything was statically linked, you had to be mindful
of the size of the executable and it was an "optimization" to leave all
the math stuff in a separate library so that it wouldn't accidently get
pulled in unless you wanted it.  This separation continues to this day
on some POSIX platforms even though nobody uses static linking any more,
so there's no real point to it.  Cygwin just puts everything in one
library, cygwin1.dll, so there is no point in this superfluous "-lm"
business, but it provides a "libm" for Makefiles that hard-code -lm.

> On linux I can build perl with -Duselongdouble, on Cygwin I can't.

Because linux has a C99-conforming libc where Cygwin doesn't.

Oh ... it's probably just ignorance on my part.
If I can successfully run 'gcc script.c' (where 'script.c' contains a 
call to 'sqrtl') then I'm inclined to say that sqrtl is "available in 
the C compiler" (or something like that).
If your position is that availability as a built-in should suffice, you 
may have a long row to hoe.


I gather from your response (and Corinna's) that there are also a couple 
of things called 'newlib' and 'libc' that enter into the equation.
gcc itself supports only built-in functions.  There are plenty of posts 
in the archives concerning why cygwin doesn't use glibc rather than newlib.


I find it all quite confusing. My MinGW version of math.h specifically 
prototypes the "long double" version of a number of functions (ceill, 
floorl, sqrtl, modfl, ...), yet I can't find any mention of those 
functions in any of the gcc headers on Linux or Cygwin.
mingw relies on Microsoft library support, where again there is no 
separate long double.  You are free to add prototypes to your cygwin 
, but you must take the further step of actually supplying a 
function.  It should not be difficult to make one for cygwin which 
satisfies your purposes, whatever they are.  For example, you could 
build a function which uses the built-in, with its limitations.

If I call sqrtl on linux I have to link to -lm, on Cygwin I don't.


Most compilers on linux also have a built-in sqrtl.  If you set the 
right options in gcc, for example, you should be able to make a simple 
test which gets by with that.  You may have to check for bugs in 
mathinline.h.  Many distros do ugly things which can't be blamed on gcc 
or glibc maintainers.

/usr/bin is a link to /bin

Why do you say this?


Oh ... it's probably just ignorance on my part.
If I can successfully run 'gcc script.c' (where 'script.c' contains a call 
to 'sqrtl') then I'm inclined to say that sqrtl is "available in the C 
compiler" (or something like that).


I gather from your response (and Corinna's) that there are also a couple of 
things called 'newlib' and 'libc' that enter into the equation. I don't know 
how they fit in. Feel free to enlighten me (but only if you're so inclined, 
as I realise that such an explanation is probably not on topic for this 
list).


I find it all quite confusing. My MinGW version of math.h specifically 
prototypes the "long double" version of a number of functions (ceill, 
floorl, sqrtl, modfl, ...), yet I can't find any mention of those functions 
in any of the gcc headers on Linux or Cygwin.


If I call sqrtl on linux I have to link to -lm, on Cygwin I don't.

On linux I can build perl with -Duselongdouble, on Cygwin I can't.

Anyway  I gather that -Duselongdouble is out of the question while 
newlib remains in its current state. (That's pretty much the confirmation I 
was seeking.)


Thanks guys.

Cheers,
Rob

Also note that until frexpl is implemented, you can make printf in a CVS
snapshot of cygwin go into an infloop or coredump with certain long double
values.

Why do you say this?  It's not available.  And it's not something the
compiler provides, it's something the libc provides, and in the case of
newlib, none of these three functions exist, so the results are
expected.  At the moment newlib only supports long double I/O, i.e.
printf and scanf.

Long double functions are not supported by newlib so far.  There are a
couple of C99 functions not available in newlib.  Volunteers implementing
these functions in a license compatible way (BSD, not GPL) in newlib
are always welcome.

Cygwin Perl and -Duselongdouble

[Sisyphus]

Hi,
I'd like to have a perl on Cygwin built with -Duselongdouble, so I tried 
building blead (5.9.5) from source with:


./configure -de -Dusemorebits -Dprefix=~/Rob -Dusethreads -Uusemymalloc -Doptimize=-O3 
-Dusedevel


but that failed, culminating as follows:


.
.
sqrtl() NOT found.

scalbnl() NOT found.

modfl() NOT found.

modfl() prototype NOT found.

*** You requested the use of long doubles but you do not seem to have
*** the following mathematical functions needed for long double support:
*** sqrtl modfl frexpl
*** Please rerun Configure without -Duselongdouble and/or -Dusemorebits.
*** Cannot continue, aborting.


I haven't checked for 'modfl' and 'frexpl', but 'sqrtl' at least seems to be 
available in the C compiler. Why does configure report that it's not 
available ? (I don't need a detailed account ... rather I'm just seeking 
confirmation that the error is valid and well founded :-)


By way of explanation, I find that perls built with -Duse64bitint but 
not -Duselongdouble don't DWIM very well. For example (with my current 
Cygwin build of perl 5.8.7 built with -Duse64bit int):


-
[EMAIL PROTECTED] ~/comp/perl-5.9.5
$ perl -e 'print "Crap" if 2 ** 55 + 6 == 2 ** 55 + 7'
Crap
[EMAIL PROTECTED] ~/comp/perl-5.9.5
-

As I understand it, that's typical of *all* perls built with -Duse64bitint 
but not -Duselongdouble, not just Cygwin. (Build with -Duselongdouble as 
well and it doesn't print "Crap" ... on linux, at least.)


Cheers,
Rob

Remove the "h" in the above recipe.  AFAICT, specifying "h" causes
procmail to only use the header and not the body.  The man page has the
following relevant albeit confusing information:

If you specify only a `h' or a `b' flag on a delivering recipe, and
the recipe matches, then, unless the `c' flag is present as well,
the body respectively the header of the mail will be silently lost.

Re: Using 'complex.h' and GCC-3.4.4-3 in Cygwin

I suppose newlib doesn't provide a full C99 implementation yet.
This message would seem to confirm that:
  http://www.cygwin.com/ml/cygwin/2006-07/msg00758.html

> test_complex_h.c: In function `main':

If you change that line this way:

- printf("sizeof(%s) = %ld\n",   "complex float", sizeof(float complex));
+ printf("sizeof(%s) = %ld\n",   "complex float", sizeof(float _Complex));

then it compiles, and running it gives
  sizeof(complex float) = 8
so gcc has some support built in, though the C library doesn't
implement the macro defined in C99 7.3.1/2 . It seems to be
lacking the complex functions, too: I get
  undefined reference to `_cexpf'
if I try to use cexpf() by providing my own prototype.

Using 'complex.h' and GCC-3.4.4-3 in Cygwin

[Angelo Graziosi]

On Cygwin, gcc-3.4.4-3 (curr) fails to compile this simple test case
(extracted by a little elaborate test) :

==
#include 
#include 
#include 
#include 

int main()
{
   printf("sizeof(%s) = %ld\n",   "complex float", sizeof(float complex));

   return 0;
}


$ gcc test_complex_h.c
test_complex_h.c:3:21: complex.h: No such file or directory
     ???

test_complex_h.c: In function `main':
test_complex_h.c:8: error: parse error before "complex"
==

On GNU/Linux Kubunto 6.06 with gcc-4.0.3 it is build without problems.


Cheers,

   Angelo.

Sorry, my error. When using the drive, SHELL and HOME are set in the 
Windows environment before starting bash; on the stick, this is not the 
case. Testing confirms this difference in preamble to be the reason for 
the difference in behaviour reported. Sorry to waste your time.

Where, or how, is BASH set?

[fergus]

Sorry, a very individual query:
I have two portable Cygwins, one on a stick, one on a mobile drive. They 
are both up-to-date though only the one on the drive is a Full 
installation. In all other respects they are not obviously different 
(mounting -buf at the start, un-mounting at the end, etc) and each is 
started in a bash shell. They have identical /etc/group and /etc/passwd. 
After starting the one on the drive, a selection from the output of set 
gives

BASH=/usr/bin/bash
HOME=/home/user
SHELL=/bin/bash
while the one on the stick has
BASH=/bin/bash
HOME=/home/user
SHELL=/bin/bash
I do not understand how this difference (in the definition of BASH) 
arises though I can see it shouldn't matter. It's the only difference in 
the entire output from set on the two devices.
On the drive I can type rxvt  and immediately get into a rxvt 
shell with $HOME/.bashrc read. This is odd (I would have expected to 
have to type rxvt -e bash ) but convenient because of the reduced 
typing. On the stick I actually do have to type rxvt -e bash ; 
the reduced form rxvt  does not read $HOME/.bashrc and I end up 
in a rxvt terminal with

BASH=/usr/bin/sh
This, conversely, is expected (but, in comparison, inconvenient).
Regardless of expectedness/ unexpectedness/ convenience, I would really 
like to understand the reason for the difference in behaviours. But I 
really do not want to bother you with loads of individualised corollary 
information (and last time I did I somehow sent it en clair to people's 
mailboxes and got admonished by somebody or other in the good ol' 
imperial manner) ... it would be good if an expert could explain the 
strange difference in the initial setting of BASH; or tell me where or 
how BASH is set so that I could try to explore the difference myself; 
and offer some kind of expert conjecture on whether the difference in 
the setting of BASH could be relevant to the different consequences of 
typing rxvt   at the bash prompt on the two devices.

Thank you.
Fergus
