[Chimera-users] os x tiger

[Thomas Goddard]

Hi Grant,

  Here's an update on Chimera on Tiger.

  Chimera 1.2105 and earlier versions won't start on Tiger (Mac OS 10.4)
because Chimera includes jpeg and tiff dynamic libraries that conflict
with new libraries in Tiger.  Yesterday I removed those conflicting libraries
from Chimera, and recompiled another module that needs them (called _imaging)
to link statically.  Then Chimera starts on Tiger.

  Unfortunately with that problem taken care of I found that Chimera
crashes when displaying a molecule ribbon.  The crash dump shows it is
in the Tiger OpenGL driver.  This is likely a driver bug that Apple
will have to fix and that may take months.  I also found that
molecular surfaces disappear as soon as you rotate the models.  That
may be the same or another OpenGL driver bug.  I have only tested on
my Mac with Radeon 9800 Pro graphics.  The bug may not happen with
Nvidia graphics cards or other ATI cards.

  I will try to make a version of Chimera that will start on Tiger
available later today or tomorrow so you can try it with your graphics
card.  I'll send email when it is available to try.
