Link errors

I have also problem with linking.

Does a missing .lib file cause linking errors?

What does the linker mean with unresolved external symbol?

Yes. A linker links lib and object files. If one is missing, that''s a linker error.

It means a symbol used in one of the modules (lib or obj files) isn''t found in any file used in the linking process. There''s some code using for instance "printf", but no library containing the compiled code for it.

#pragma comment(lib, "glut32.lib") underneath the includes. I THINK the filename is glut32.lib, but I''m not 100% sure on that since I don''t use GLUT.

No, it''s not that I''ve already linked glut32.lib. It must be something else, but what?

Question: A quick search makes me believe there''s something about those two functions - I can''t find mention of them anywhere, except a few people who also had trouble with linking them (none got a reply though). The glut API docs at http://www.opengl.org/developers/documentation/glut/spec3/spec3.html does not include those functions.

So, what are they? Where did you find them?

I had a similar (perhaps identical) error message earlier tonight while trying to get a glut app running in Dev-C++. The error was in fact corrected by linking the proper glut library. I think I was at first linking glut rather than glut32, but now as I try to retrace my steps to repeat the error so I can make sure what I''m telling you is accurate, I can''t seem to get that error anymore. I hope this helps at all.

I don''t know what these function really do, but some versions of GLUT seems to replace glutInit with glutInitWithExit (same for CreateWindow). To disable this, put a #define GLUT_DISABLE_ATEXIT_HACK before including GL/glut.h. Not 100% sure about the name of the define though.
