Problems linking libraries

(1/6) > >>

Hiya,

Tried compiling several demos and its all fine till I reach any that needs libraries (eg OpenGL).

Errors I get are:
Main.cpp     undefined reference to 'glViewport@16'
Main.cpp     undefined reference to 'glMatrixMode@4'
etc

I have tried linking them under
Project -> Build Options -> Linker (under both release and debug and root)

Also the code has

--- Code: ---#pragma comment(lib, "opengl32.lib")
#pragma comment(lib, "glu32.lib")
--- End code ---

So I cant see whats wrong.... can someone give me a step by step guide in case I am missing anything stupid...

Thanks

Those are libraries you need to link with to build basic OpenGL applications.

Either add -lopengl32 -lglu32 to "other linker options", or add opengl32 and glu32 to link libraries on the left, or link against opengl32.dll and glu32.dll which are both found inside WINDOWS\system32.

Ooooookay.... the -lopengl32 and -lglu32 in other linker options worked.... my next question is why and what does it actually do when you do that?

rickg22:
-l is the GCC command to link a library. For some reason adding them to the linker libraries list didn't work in your case.... (weird)

It's not exactly "weird"...
He used #pragmas to link the libraries. These only work in MS compilers...
