Missing libglx.a

slott_hansen · 10-21-2005, 02:02 AM

I used to have a Nvidia gfx card but due to lack of 64bit support I switched to ATI. Now everything is up and running with the fglrx driver - but my glx is missing. When ever I turn on my GLX module X fails due to a missing libglx.a file.

Which package will install this for me - and why didn't the ATI drivers supply one ?

My system is a Fedora core 4 running on a 3 ghz pentium 64 bit.

The Nvidia drivers replace the GLX package. I usually get it back by forcing a reinstall of the xorg-x11 package, i.e. get the RPM and do

rpm -i --force xorg-x11-<whatever>.rpm

You can also use rpm2cpio to make a cpio archive and just extra the libglx file and put it back into the X11 lib directory, but I've never had a problem forcing the reinstall.

HTH.

Nice move using the rpm2cpio - I managed to extract the missing libglx.a and move it to it's correct place.
Now my X starts with the "load glx" but still I have no GLX support !!!!

Code:

[msh@localhost ~]$ glxgears
Xlib:  extension "GLX" missing on display ":0.0".
glxgears: Error: couldn't get an RGB, Double-buffered visual.

[msh@localhost ~]$ fgl_glxgears
Using GLX_SGIX_pbuffer
Xlib:  extension "GLX" missing on display ":0.0".
Error: couldn't get an RGBA, Double-buffered visual

In my X log I can see the following

And looking in that directory shows me that everything is in place - note that the libglx.a is indeed from today :-)

Any idea on how to resolve this issue ?
