I have problem with linking and here is
what is reported to me.Compile went OK.

vezba 05 17 gl.exe - 18 error(s), 0 warning(s)

The kode is not mine, the libreries included are Glut.h and gl.h which I resently downloaded.

You need to link opengl32.lib in your project settings.

3

yup, but also link glut32.lib

4

Libs are included but new problem
is here (who would thought so)
and now it is this:
--------------------Configuration: vezba 05 17 gl - Win32 Debug--------------------
Linking…
LINK : fatal error LNK1104: cannot open file “glut32.lib”
Error executing link.exe.

Did you download the glut32.lib file? And did you place it in one of the library search paths?

I think I also have a problem along the same lines, because I’m running a Borland 5.02 compiler on Windows 2000 and it’s telling me it can’t open GL.h or glut.h. I know I have the headers in my include directory. I don’t understand all that jazz about library paths either…can you help?

7

i don’t know much about borland, but in MSVC, you specify folders to look in for headers and libraries. these folders get searched when you #include a header. the library files you link your program with must be in the folders you have specified. if not, you’ll get linker errors.

I have found an answer for my question on another forum.
To make things as simple as possible I have to make 2 points about this problem

  1. The forum I have found answers is not written in English.
  2. There had to do several tings just to prepare compiler:
    Some of them are:
  3. Download glut.h glut.dll and glut.lib from this address: http://www.xmission.com/~nate/glut.html
  4. Place glut.h in folder include/Gl/ which already contained gl.h and glu.h
  5. Place glut.dll in my C:/windows/system folder.
  6. Place glut.lib in my lib folder.
  7. I had to add couple of .lib files for linking (opengl32.lib, glu32.lib, and glut32.lib)
    and in VC++ that is done in Project -> Settings -> Link

Yeah, downloading the required files usually helps

I had to go through all that a couple weeks ago so I know how you feel!
