[GRASSLIST:1739] RE: r3.showdspf.openGL

[Charles Beaudry]

I fixed the problem by downloading the sources for LESSTIF and building the
libraries for my system.  I tried to build g3d again but got stuck in
r3.showdspf.openGL this time because of  some problem with
GLwCreateMDrawingArea.  Here follows the output of the g3d build process
along with the output from the part of the configure program that checks out
Mesa.

I suspect that the version of the widgets I have does not contain
GLwCreateMDrawingArea and I need it. Could it be that it cannot find the
widget?  I have the headers GLwDrawA.h, GLwDrawAP.h, GLwMDrawA.h, and
GLwMDrawAM.h stored in /usr/include/GL.  The function GLwCreateMDrawingArea
is present in GLwDrawA.h so I cannot figure what is happening.  What does
(cached) mean?
