[chimera-dev] Chimera binary code issue

[Tom Goddard]

Hi Jupiter,

  Chimera is linked against the OpenGL library on your system.  Whether that uses Mesa or an Nvidia or ATI driver is up to your system -- it will not help to recompile Chimera.  The only thing that could help is installing a different system OpenGL driver.

  You are trying to make your life difficult running Chimera on a virtual machine and remote display with an X11 VNC client. Your problem is entirely a computer configuration issue, nothing in Chimera can fix it.  You'd save yourself a lot of frustration by running Chimera on an OS with a native OpenGL driver.
