It seems that there is a SUN_OGL_NO_VERTEX_MACROS define that I should
set. If I google that, I get a lot of source references, and a few
people who had to use it. I'm trying it now. One of them said that
Sun's GLU wouldn't work if you compile your code with this define.
Here is one comment:
SunOS: OpenGL apps must be compiled with SUN_OGL_NO_VERTEX_MACROS
defined so that macros aren't used for OpenGL API functions. This also
means that Sun's stock GLUT and GLU libraries won't work with Chromium.
After you've produced new GLUT and GLU libraries you may have to edit
SunOS.mk and modify your LD_LIBRARY_PATH to select the new libraries.
Another:
- I had to specify "-DSUN_OGL_NO_VERTEX_MACROS" on the
compile line for source files that called OpenGL routines using
the scope operator (e.g. "::glColor4fv( p );"). Loosely
speaking,
SUN implements OpenGl calls indirectly through some sort of table
of function pointers (via #define) "for performance reasons".
The
scope operator "::" says there is a global function to call
which
is not found and results in a compiler error. The
"SUN_OGL_NO_VERTEX_MACROS" macro specifies
that the actual OpenGl routines are to be accessed and fixes the
problem. The alternative is to remove the scope operator from the
OpenGl calls.
So they had a problem when the :: was there, and we're having a problem
because this isn't a call, but a declaration.
I think your approach will resolve it without me having to wonder about
side effects to using that define above.
thanks

I'll go ahead an rename the methods, just removing the gl prefix.
I'll check in this change once I've got things built.
Robert.
