Bug 114537 – modular Xorg (7.0.0rc3) unresolved symbols for opengl interface

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Felix Braun 2005-12-05 08:05:38 UTC]

I just updated my modular Xorg build. The compilation of xdriinfo aborts with
the following error:

checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for XDRIINFO... yes
checking for library containing glXGetProcAddress... no
configure: error: cannot find GL library - make sure Mesa or other OpenGL
package is installed

even though I have mesa-6.4.1 installed. Is glXGetProcAdderess provided in a
newer version of mesa? Anyway, the ebuild should depend on a library that
provides that function.

xdiinfo-0.99.1 works fine on this system.

A revdep-rebuild (rebuilding mesa) fixed the issue for me. Maybe xserver's
ebuild should be updated to suggest such a rebuild?

[Comment 4 Joshua Baergen (RETIRED) 2005-12-05 09:31:39 UTC]

This is likely due to the libdrm changes...Donnie, should we rev-bump mesa and
force it in the metabuild to avoid this?

[Comment 5 Felix Braun 2005-12-05 10:06:31 UTC]

But now the xorg-server can't load its GLcore module anymore (libGLcore.so:
undefined symbol: __glXLastContext)

:-(

Which xorg-server are you running?  I bumped it last night with a libdrm dep
that might fix it...

No, that's not the right answer. Running revdep-rebuild is.

In reply to comment #6:
The bug with __glXLastContext is present in both xorg-server-0.99.4-r1 and -r2.

Please attach your 'emerge info' and attach your X configuration and log.

You shouldn't load GLcore explicitly.  The dynamic loader will start it as
required.  Drop the line from your xorg.conf and you shouldn't lose any
functionality.
