As Tim says, the problem is in clib/ogl_bitmap_character.c. I have found
that changing this code to use the standard glutBitmapCharacter routine
instead of its own ogl_bitmap_character makes it work (under Fedora Core
4 Linux, anyway). Try replacing your clib/ogl_bitmap_character.c with
the following:
==========================================================================
/*
OpenGL bitmap string output.
Copyright (C) 1998 Per Kraulis
6-Feb-1998 first attempts
*/
/* public ====================
#include <GL/glut.h>
==================== public */
#include <assert.h>
/*------------------------------------------------------------*/
void
ogl_bitmap_string (void *font, char *str)
/*
Output the string using the given GLUT bitmap font.
The font must be a GLUTbitmapFont.
The raster position must be defined.
*/
{
/* pre */
assert (font);
assert (str);
for ( ; *str; str++) glutBitmapCharacter (font, *str);
}

I can get molscript to compile, but have problems getting the labels to

machine, using render on linux.
Funny you should mention that. Ron Stenkamp brought the same problem
to my attention last week, thinking that it was a problem with render.
After some poking around, we established conclusively that the labels
were never making it into the Raster3D input file.
Furthermore, if I recall correctly, the same molscript executable
would produce labels when run on one machine but not another
(Ron - please fill in details!).
So I concluded that the problem was actually in some support library,
but I do not know which one that would be.
Ah, I remember this one now. clib/ogl_bitmap_character.c contains
BitmapFonts, which are deprecated/broken in freeglut. I changed this
to just use raster3d object types 10/11/12, so I've been thinking of
everything in terms of label3d. povscript+ has the fix, if its of any
value.
