I have more information now. The problem is an incompatibilty with DRM/DRI
in the xserver. The machine on which XOP works fine does not have a working
DRI. When I disable the loading of the dri module in a machine in which XOP
was not functioning, it now works, although it spits out some error messages
as shown below. It may be that thereis a way to make the program work with
DRI enables but I have not figured it out yet.
The actual problem was with the GL libraries in Debian conflicting with
the libraries shipped with XOP. When DRI is disabled, the program drops
back to non-accelerated operation and this works fine. The fix is to
remove the libraries that ship with XOP
xop2.1/idl_6.0/bin/bin.linux.x86/gl_driver.so
xop2.1/idl_6.0/bin/bin.linux.x86/gl_driver.so.6.0
The the program uses the Debian libraries and works fine in accelerated
mode! Once I knew that there was a problem with DRI causing the
segmentation fault, I was able to find the following thread on the ITT web
site.
