I'm pretty sure BLFS has it backwards. No one really works on either of the GLUTs, but Mesa's has the troublesome license.

So, you'd have to install Mesa then FreeGLUT. FWIW, nothing else in the Xorg stack uses GLUT, so you can definitely postpone FreeGLUT until later.

It's just convenience utilities on top of GL which makes developing GL applications easier (apparently). There are a couple free implementations available: Mesa's GLUT with the troublesome license, or FreeGLUT, which was started to address this license problem (I think). -- Dan -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
