Hi there,
I realize this may not be directly related to Unix, but I have recently been using an fMRI analysis program called FreeSurfer which is primarily run in the tclsh shell. However, I have been unable to open up the GUI, and I get the following error message when I attempt to do so:
GLUT: Fatal Error in tkmedit.bin: OpenGL GLX extension not supported by
display: 1.0
The output of 'cat /etc/redhat-release' is
Red Hat Enterprise Linux WS release r (Nahant Update 7)
and here is the output from the command ldd `which tkmedit.bin`:
