Thread: Problems with OpenGL(glut) in C++

I'm only "guessing based on what I happened to find on the web", but perhaps you should use "-lglut32"?

http://www.xmission.com/~nate/glut/README-win32.txt

If that fails, open a command prompt window, and do "dir /s/b *glut*lib" on the disk where you expect to find your library files. If it's not obvious to you what's the right answer, post the output of this command here. [assuming of course it's not HUGE - it shouldn't be].

Really - are you sure that what happens isn't that you ALSO need some other library to support GLUT?


Again, I may be horribly wrong here, but perhaps this link gives the right answer:
http://www.cosc.brocku.ca/Offerings/...vcnetglut.html

It links to:
opengl32.lib, glu32.lib, glaux.lib glut32.lib
In gcc that would be:
-lopengl32 -lglu32 -lglaux -lglut32

If you only have -lglut32 I would expect lots of linker errors because glut32 depends on other things.

But again, I'm just guessing.

However, if you are definitely sure that those glut... undefined symbols are gone (and not jjust hiding in a bigger pile of undefined symbols) then I would say that part of the problem is that you don't link in some other necessary libraries.

I don't think that's actually part of the problem. But perhaps you can make Dev-C++ generate a makefile and post that here?

I know several regulars use Dev-C++ here - I don't, I use gcc sometimes, but in conjunction with Emacs as the "IDE" - only because I'm used to Emacs.

If you do it on the command line, you would do something like this:
gcc -o myprog myprog.o myfuncs.o -lopengl32 -lglu32 -lglaux -lglut32

You may need OTHER -lxxx too - perhaps -lm for example for math functions.

And of course the "myprog" and "mufuncs" would be names of your files that have been previously compiled into object files.

Also, you don't need to BUY Visual Studio. There is a free version, Visual Studio Express Edition, that is available from MS for no fee at all. Should be as good as any gcc-based produce when it comes to "what you can do", but slightly more "slick" in the integration of the tools into an IDE [my personal opinion].
