[Octave-bug-tracker] [bug #52998] Segmentation fault for OpenGL printing of non-visible figures

[Dan Sebald]

Follow-up Comment #7, bug #52998 (project octave):

Thanks for the tip, but that doesn't work either:


linux@ ~/octave/bug/52998 $ LIBGL_ALWAYS_SOFTWARE=1
LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libGL.so
/usr/local/src/octave/octave/build1/run-octave --no-gui
[snip]
octave:1> graphics_toolkit qt
octave:2> set(gcf, 'visible', 'off')
octave:3> libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
exit
[hang]


SWRAST is one of the OpenGL drivers, deprecated.  I probably don't have it
installed.  Strange this works to generate manual figures... I'm looking at
that right now.
