[Mesa-dev] Help for a beginner

[Heath Feather]

Julian,

Try seeing which libraries you're picking up , here my LD_LIBRARY_PATH
was set to /home/hfeather/work/downloads/Mesa-7.0.1/lib64/

> which glxinfo
/usr/bin/glxinfo
> ldd /usr/bin/glxinfo
        libGL.so.1 =>
/home/hfeather/work/downloads/Mesa-7.0.1/lib64/libGL.so.1
(0x00002af16f371000)
        libGLU.so.1 =>
/home/hfeather/work/downloads/Mesa-7.0.1/lib64/libGLU.so.1
(0x00002af16f84c000)
        libc.so.6 => /lib64/libc.so.6 (0x00000030ffc00000)
        libX11.so.6 => /usr/lib64/libX11.so.6 (0x0000003101000000)
        libXext.so.6 => /usr/lib64/libXext.so.6 (0x0000003101c00000)
        libm.so.6 => /lib64/libm.so.6 (0x0000003100000000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x0000003100800000)
        libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x0000003106000000)
        libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x0000003105c00000)
        /lib64/ld-linux-x86-64.so.2 (0x00000030ff800000)
        libXau.so.6 => /usr/lib64/libXau.so.6 (0x0000003101800000)
        libXdmcp.so.6 => /usr/lib64/libXdmcp.so.6 (0x0000003101400000)
        libdl.so.2 => /lib64/libdl.so.2 (0x0000003100400000)

At least you'll know what your're picking up

It would help to see the rest of glxinfo, but it might be that you're
just not picking up the new dri driver.  Try setting the
LIBGL_DRIVERS_PATH env var to point to the location of the *_dri.so
modules.

Otherwise, set LIBGL_DEBUG=verbose and re-run glxinfo to see if anything
is going wrong.
