Getting OpenGL/GLUT to work

[102jon]

Hi, I'm working on my first graphics project using the Codeblocks IDE with MinGW compiler. I recently downloaded freeglut for windows. In my source code I made sure to include the GL/glut.h file, however I receive this error message upon compiling:


ld.exe||cannot find -lglut32|
||=== Build finished: 1 errors, 0 warnings ===|

Any insight would be greatly appreciated.

Correction, my compiler is GNU GCC.

Thats a linker error. Basically glut.h defines classes, and functions, etc which are then implemented in the glut32.lib file. -lglut32 just tells the linker that you need to include the glut32.lib file in the executable. The problem it is having is just as it says, it cannot find glut32.lib. In codeblocks, go Settings->Compiler and Debugger->Search Directories->Linker and make sure the glut32.lib file is in one of those directories.

When I downloaded freeglut, the only .lib file there is freeglut.lib. Did I download the wrong windows binary or something?

Whoops, my eyes jumped over the part where you mentioned freeglut. Freeglut uses freeglut.lib, but in order to make it compatible with other people's code, the creators decided to use the same name as glut's header file, "GL/glut.h".Well if the lib is freeglut.lib you should be able to use the linker option -lfreeglut to link with it. And you can always use Settings->Compiler and Debugger->Linker->Link Libraries because you show Codeblocks both the library and its directory.
