To be more precise, I had to compile a custom Mesa due to lack of support for WebGL on my laptop (Intel GMA945).

So, compiled Mesa 7.8.1 with this configure:
CFLAGS=-DUSE_MGL_NAMESPACE ./configure --disable-glu --disable-glut --disable-egl --disable-glw --with-driver=osmesa

Then enabled webgl via about:config, by defining webgl.enabled_for_all_sites to true and webgl.osmesalib to /home/alex/tmp/mesa/Mesa-7.8.1/lib/libOSMesa.so

alex@portable-alex:~/tmp/mesa/Mesa-7.8.1$ file  /home/alex/tmp/mesa/Mesa-7.8.1/lib/libOSMesa.so
/home/alex/tmp/mesa/Mesa-7.8.1/lib/libOSMesa.so: symbolic link to `libOSMesa.so.7'
alex@portable-alex:~/tmp/mesa/Mesa-7.8.1$ file  /home/alex/tmp/mesa/Mesa-7.8.1/lib/libOSMesa.so.7.8.1

Don't crash on failure to create a WebGL pbuffer, v2

This shouldn't be necessary any more -- just checked in some code that adds support for OSMesa, and as part of it it errors out if gl remains null.

[:gerard-majax]

Cool. Will it be present in the nightly builds tomorrow ?

Comment 7

[Julien]

Fixed in current nightly build, nice.

Comment 8

[:gerard-majax]

I confirm it's fixed.

I'm unsure wether it's the correct place to ask, but is it normal that I can't use WebGL via OSmesa ?

Here is what I have in the console:
Canvas 3D: creating PBuffer...
Canvas 3D: can't get a native PBuffer, trying OSMesa...
Canvas 3D: can't create a OSMesa pseudo-PBuffer.

I have webgl.osmesalib set up to '/home/alex/tmp/mesa/Mesa-7.8.1/lib/libOSMesa.so', which is a version of Mesa compiled with USE_MGL_NAMESPACE.
