Problems with linking

Hi NG.

I am a newbie on the window platform. I have some OpenGL programs that i want to compile under win2k.

I am using mingw and the Dev C++ IDE. I have succesfully compiled and linked some small toy programs by using -lglut32 -lglu32 -lopengl32.

I now have a problem with a somewhat more advanced piece of code that uses som nvidia extensions. The problem is that i get unresolved references.

I have tried to link with the nvoglnt.dll by using -lnvoglnt but that does not seem to do the trick. Right now my line of thougt is that i should try to use the impdef.exe tool on nvoglnt.dll to get a .def file so that i later can make a .a file by using dlltool.exe.

Somehow, this seems complicated and i have a feeling that this might not be the correct approach. Should linking by

-lglut32 -lglu32 -lopengl32.

work even when using vendor extensions? And if yes, how does it work? I mean the vendor information must surely be hidden in i.e. nvoglnt.dll for nvidia supplied extensions.

Hope to get some comments or links


My problem was unresolved references of the type imp_ for all my OpenGL calls.

As it turns out, the problem was that the code did not include gl.h. Instead it included glut.h which is supposed to include gl.h - or so i thought. In linux i works fine, but in windows I have to specifically include gl.h.

I think i remember someone telling me that it was best to let glut.h include gl.h - was i the documentation? yes it was!

See GLUT API version 3 section 1.5 Conventions (second half).

Anyway, the conclusion might be that unresolved references of the type imp_ could be due to header issues.

You getting this messages bebause of no actually LIB files linked to Your program. Which version of MS VC++ You are using?

As you may not know, under windows, the opengl32.dll does NOT have any extention entry point. To solve this, see :
