#34 OpenGL related crashes on Mandrake8.1

[Anonymous]

Mandrake 8.1
( My own kernel 2.4.18-pre6 )
Your Binary Release 1.1

ldd rendrib
/lib/libsafe.so.2 => /lib/libsafe.so.2 (0x40018000)
libGL.so.1 => /usr/X11R6/lib/libGL.so.1 (0x40043000)
libGLU.so.1 => /usr/X11R6/lib/libGLU.so.1 (0x40063000)
libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40085000)
libm.so.6 => /lib/libm.so.6 (0x4016f000)
libdl.so.2 => /lib/libdl.so.2 (0x40192000)
libc.so.6 => /lib/libc.so.6 (0x40196000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

CTRL+R - render, yeilds Red Message at the bottom of
the screen "Error loading libGL.so.1.2"

( Seems like rendrib itself
does not want libGL.so.1.2 so you must
want libGL.so.1.2 )

Then, OCCASIONALLY, usually when Creating Viewer,
an actual crash can happen, I will see output
from a terminal window like follows after
starting from command-line and running for
awhile until this crash happens:
-------------------------------------

Loading required GL library usr/X11R6/lib/libGL.so.1.2
Loading required GL library usr/X11R6/lib/libGL.so.1.2
Loading required GL library usr/X11R6/lib/libGL.so.1.2
( once for each time I press CTRL+R )

Funny thing is, it seems to render the image
with the "material applied", just the progress
box dies.

Anyway, the final message that can crash when
creating a view is:
----------------------------------------------
Segmentation fault

( and working with light sources is not very easy )

No, ldd ./ayam gives me
libGLU.so.1 => /usr/lib/libGLU.so.1
libGL.so.1 => /usr/X11R6/lib/libGL.so.1
I suspect your problems are related to your actual OpenGL.
Can you tell me which version of OpenGL you are using
(OpenGL version, vendor, driver version etc.)?
Or, can you switch temorarily to Mesa, to see if this cures
things?

About the light sources, can you please be a little bit more
constructive? Given the possible complexity of light sources
in the RenderMan context, working with them is quite easy
for me. But you surely have your own ideas about that.
Share them!

best regards,
Randolf,

The OP mailed back, that he was able to resolve the problems
using a self compiled and installed Mesa V4.0.1.
