>try linking to just glut.lib ?
Glut32.lib?  Nope, a whole lot of linker errors still.

Firstly..Why do you need to create projects, there are project already
in Mesa/win32/3dfx (or at least there are in mine)
and secondly, are you sure the new compiled libraries are
in your path statement.
Either add then in to the preoject settings or possibly better
is to copy them all into the vc/lib and vc/include
directories, (backing up anything you replace)
and put the Dll's in windows\system.
This way you won't have any problems accidently linking to the
old non mesa versions.
Not sure if that helps....hope it does :-)

I guess your using the wrong 'calling convetion'. You should change the
setting  to 'stdcall' in the 'Project settings-> C/C++ -> Code
generation -> Calling convetion'. This should fix your problem.

It is a "bug" in the gl.h (the function prototypes are wrong) included
in the Mesa. The latest sources available at Mesa CVS should not include
this bug.

BTW, the easiest way to use Mesa under Win is to link with the standard
Microsoft Opengl32.lib and to copy the Mesa DLLs in the directory where
you run your application (so it is also very easy to switch between Mesa
and system OpenGL, you have only to delete or copy the Mesa DLLs).

I only got Mesa a few days ago...

Well I did copy the Mesa opengl32.lib things into the VC lib folder.
Could this be causing the above probs?

(Linux never had this trouble, hmmmmph)
