hi @ all Maybe a kind of stupid question, but where can I get the files opengl32.lib glu32.lib, gl.h, glu.h etc? I'm using mingw32 on linux for compiling Windows-Executables, but there are only OpenGL 1.3 files included, but I need 2.0 for GLSL & co thanks Krox

There aren't any and you can blame microsoft for that (as they refuse to make new versions of it), to use openGL2.0 you have to use extensions.
go to http://www.opengl.org/registry/ and download the latest extension header files.
You could also use glew (google it).

well, thats an explanation for not finding anything on google. Thanks

gl.h and glu.h are included with mingw but lc_overlord said you have to use something like GLEW to be able to use the newest OpenGL stuff.
opengl32.lib and glu32.lib are microsoft compiler specific libraries for mingw those are called libopengl32.a and libglu32.a.
