Re: [PyMOL] Ray Tracing Bug in Pymol 0.93 on SuSE Linux 8.2

2004-02-18 Thread Thomas Siegmund
Dear Buz,

 I've been using Pymol 0.93 on SuSE Linux 8.2 for a few hours now, and I'm
 having trouble ray tracing graphics.

 Each time I start the ray tracer Pymol quits with a segmentation fault

I guess you are running into a compiler bug (or a bug in PyMol which gets 
exposed only by some compiler versions).

For me PyMol on SuSE 8.2 crashed always when raytracing a line element. The 
stock  compiler on SuSE 8.2 is gcc 3.3 20030226 (prerelease). I got the same 
crash with  gcc 3.3.1, but not with gcc 2.95. I have not tried it on SUSE 9 
yet, installing and using gcc 2.95 (for PyMol only) solved the problem for 
me. See PyMol bugreport 806361.

Dear Warren,

I installed it with python distutils from source. See the bug report I filed 
in the meantime for details. It turned out to be a problem with some versions 
of gcc - crash when raytracing lines, sticks or meshes with gcc (GCC) 3.3 
20030226 (prerelease) (SuSE Linux) and with gcc 3.3.1, but a perfectly 
stable PyMOL with good old gcc 2.95.3.

Best regards

   I tried running your script on the current development version
 and on a version 0.90 binary, and wasn't able to get PyMOL to crash.

   How is PyMOL installed on your system?

  Hi everybody,
  I am new to pymol. So maybe I'm doing something wrong, but pymol


  everytime crashes when I try to raytrace a picture. I had some success
  small protein structures in cartoon representation. The same molecule
