Problem with OpenGL on new X serverl
Your patch doesn't fix the SEGV.
I know this is off-topic but can you tell me if there is a simple way
to compile in debug mode using cygport ?

Hi Florent,
Thanks for the bug report.
Ignore the GetWindowProp - pWin or name was NULL, this is just log spam
and a red herring.
As you have surmised, the problem is GLX related. There are some reports of
remote GLX clients working (Ubuntu 8.10), so perhaps it is related to the
client being built for an older version of the GLX extension...
If you are able to rebuild the X server yourself, could you confirm that the
attached patch fixes the crash (GL is still broken, though, it looks like
the something isn't initialized correctly...)
Rebuilding the source *should* be as simple as:
1) Run cygwin setup, select cygport,the xorg-server source package, and the
packages for the build-time dependencies and devel packages corresponding to
run-time dependencies listed in /usr/share/doc/Cygwin/usr/share/doc/Cygwin
2) cd /usr/src/
3) cygport xorg-server-1.5.3-3.cygport prep compile
I have made a start at updating
http://x.cygwin.com/docs/cg/cygwin-x-cg.html, so you may find that helpful,
but it still needs more work so don't take it as gospel.

After a grep in the sources, I see the error is from file
cygwin-net_wm_icon-support.patch. But i'm not sure that the error is
in relation with the crash. I will try to run the program under a
debugger.

Hello,
I have a crash when opening OpenGL. I have the same configuration than
you :
ssh -X host ; XWin with glx extension activated.
Some of my investigations :
1. It's not caused by the X client OS (SunOS and Linux give the same
crash)
2. It's not a problem with our application, glxinfo produce the same
problem
3. It seems that the message GetWindowProp - pWin or name was NULL
is displayed before the crash, see my log in attachement.
I will download and check the XWin sources but I have not a lot of
time for debugging it so if someone have the same problem or want to
help me ...
Best regards,

So is there a known solution, patch or other to this issue ?
I see that you do have the libGL1 package installed. Could you please
review my results with GLX:
