I've temporarly switched to FreeBSD-STABLE, because I need working OpenGL.
Currently all pkgsrc packages buildlink MesaLib, which is a software renderer.
XFree86-libs provides a version of Mesa library, which automatically detects
presence of hardware rendering equipment.
Every package linked with graphics/MesaLib will use software rendering.
What can we do to change/improve current situation? Following ideas came to
1) quick hack; it's working and gives good results. Apply the attached diff
(called MESSA_DIFFS) over MesaLib buildlink2.mk and install libGL.la in
2) system-wide mk script: just like ossaudio and pthread, we could use
a file like "mk/opengl.buildlink2.mk". Apps which want opengl should
include that file
3) Maybe graphics/MesaLib can be build in such way it will function just like
XFree86-bundled one (autodetect rendering hardware) -- and we can make
it build this way? Anyway, this would be a bit worse situation, that 2),
just because XFree86-officially-blessed-library will always be
better, at least in terms of support and bugfixing.
Which way should we choose? Please help me decide and I can work on patches
