Hello,
So it seems that for Justin at least the issue was solved by changing one
of the GL flags in the environment.txt file (located in
ccpnmr/ccpnmr2.*/c). So changing from
GL_FLAG = -DUSE_GL_FALSE
to
GL_FLAG = -DUSE_GL_TRUE
(And then "make clean" and "make", so if you have a pre-compiled version
of the code you are unlikely to be able to do this.)
Tim says that this had to be changed "when going from Ubuntu 10.04 to
10.10". This flag determines the "direct" argument to the
glXCreateContext() function. The documentation for that says:
"If direct is True, then a direct rendering context is created if the
implementation supports direct rendering, if the connection is to an X
server that is local, and if a direct rendering context is available. (An
implementation may return an indirect context when direct is True.) If
direct is False, then a rendering context that renders through the X
server is always created. Direct rendering provides a performance
advantage in some implementations. However, direct rendering contexts
cannot be shared outside a single process, and they may be unable to
render to GLX pixmaps."
Well I'm not sure I understand all that. But GL_FLAG is one of the two
flags that might need changing if OpenGL goes wrong. (GLUT_NEED_INIT
being the other one.)
