Thread: [isugamedev-devel] how do I install GLUT?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Ok, in MSVC 6, how do I set up GLUT so that it WORKS?
which folders to the headers, dll's and libs go to, and do I need to do =
something inside MSVC? like mess with parsing or something?

I typically do this:

put the glut.h into your msvc++ include\GL\ directory
put the glut.lib into your msvc++ lib\ directory
put the glut.dll into your c:\windows\system directory

This effectively installs glut for use by visual studio.  

you'll probably see that your other opengl stuff (that comes with VC++) is
in similar places:

include\GL\gl.h
include\GL\glu.h
lib\glu32.lib
lib\OpenGL32.lib

Where the root dir is on your system depends on where you installed msvc++
to... if all else fails, just do a file search for glu.h and you'll find
where to put your headers.

alright, I'm now getting this error:

LIBC.lib(wincrt0.obj) : error LNK2001: unresolved external symbol
_WinMain@16
does this have anything to do with the GLUT libraries?

And where's the source for the square example we did today?

ahh, you probably created a new win32 project in VC++. Projects created in 
that manner actually start in the function WinMain( ... ) instead of 
main( ... ).

the easiest way to fix this is to create a new "win32 console" project 
that will use main( ... ).

on the other hand, you could just add this code to your current project:

#ifdef _WIN32
#ifndef _CONSOLE

int WINAPI WinMain(
      HINSTANCE instance,
      HINSTANCE prevInstance,
      LPSTR commandLine
      int showCommand )
{
   return main( __argc, __argv );
}

oops, that code is missing the #endifs. it should really be:

#ifdef _WIN32
#ifndef _CONSOLE

int WINAPI WinMain(
      HINSTANCE instance,
      HINSTANCE prevInstance,
      LPSTR commandLine
      int showCommand )
{
   return main( __argc, __argv );
}

#endif // ! _CONSOLE
#endif // _WIN32

I generally make a "new console project" from the new menu.  then simply
add

glut.lib OpenGL32.lib glu32.lib

to the libs tab of the project/settings menu...

I've not seen the error you're getting...

Maybe you are compiling a 16 bit windows application?

It is expecting WinMain, which you don't need in a console app, but you do
need in a Win32 app...

but winmain16 seems funny, like you made a 16 bit project or something...

Try recreating your project and see if that works...

FYI, The @16 means there are 16 bytes of arguments (four, at four bytes each). 
It's the way __stdcall mangles things by default.

In addition, you'll need to add

   glut.lib OpenGL32.lib Glu32.lib

to your libs in the VC++ project settings...
