gSystem.Load("$ROOTSYS/lib/libRGL.so");
}
I had just finished a source install of ROOT on Solaris 2.5.1 and
figured that while I was going to the trouble I'd build Mesa 3.0 and
test it out with root. Once GL.C was in place everything works just
fine as the directions say it should.
Thanks very much!
