Thanks for './configure --help', after trying a few things with it I
managed to have everything work without errors at runtime. The problem
was that nouveau was by default in '--with-dri-drivers' but not in
'--with-gallium-drivers'.


Strangely though, it displays an OpenGL version lower than with my
default mesa (and without the errors I previously got):

$ LD_LIBRARY_PATH=~/Programs/mesa/lib/gallium:~/Programs/mesa/lib LIBGL_DEBUG=verbose LIBGL_DRIVERS_PATH=~/Programs/mesa/lib/gallium:~/Programs/mesa/lib glxinfo
[...]
OpenGL renderer string: Gallium 0.4 on NV50
OpenGL version string: 2.1 Mesa 12.1.0-devel (git-ead7736)
[...]

$ glxinfo
[...]
OpenGL renderer string: Gallium 0.4 on NV50
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.5.2
[...]

I read that an unexpected low version version of OpenGL could be due
to an extension disabled due to hardware limitations, but I find it
weird that a previous version of mesa gives me a higher OpenGL
version...
Either way I can now force my OpenGL version to 4.3 with
'MESA_GL_VERSION_OVERRIDE=4.3', test what I want and hope that my
hardware supports what I use.

Thanks again,
Rémi
