I had run just cmake .. (which was described as the default). After
re-making, I can run mged and produce the .pix files on the command line. I
then used the pix-png tool to view the shapes and they are accurate. The
GUI still doesn't open up.
Also, how do I render with OpenCl? I'm assuming what I did now was the
default rendering without OpenCL.
Cheers
