Description yury fedorchenko 2015-12-02 15:13:10 UTC

mesa-11.0.6  install libGL.so and others to /usr/lib64 instead of moving it to /usr/lib64/opengl/xorg-x11/lib/ for switching by eselect opengl.


Reproducible: Always

Actual Results:  
some opengl applications don't work with nvidia-drivers wihtout LD_LIBRARY_PATH to nvidia libGL.so

Newer versions of eselect-opengl (>=1.3) should handle this, it doesn't use symlinks anymore but manipulates libary paths in /etc/env.d/000opengl and /etc/X11/xorg.conf.d/20opengl.conf

Do you have this newer eselect?

i have eselect-opengl-1.3.1-r4, but a half (only half, but i don't understand a reason) of my programs don't work with it.
i try to rebuild its, reboot, but i only have:

libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
XRequest.151: BadValue (integer parameter out of range for operation) 0x0
XRequest.151: GLXBadContext 0x600002b
XRequest.151: 0 0x0
XRequest.151: GLXBadDrawable 0x6000006
XRequest.151: GLXBadDrawable 0x6000006

but when i manualy set LD_LIBRARY_PATH to nvidia libs i cause its work.

when i reemerge mesa with my patch all work well.

P.S. I found similar problems in forum with steam.

Comment 4 yury fedorchenko 2015-12-04 09:58:29 UTC

i found the source of the problem.
the reason is that libtool generate script to start some tests from build dirs without installing and add
LD_LIBRARY_PATH=...:/usr/lib64:....
to it in some cases.

This is not mesa bug. it may be libtool bug or feature: add some system library paths to local scripts.
