If you look at one of my other posts, you can see that I was trying to write a windows wrapper class. Well, I used my copy of OpenGL Game Programming, to throw together a windows class, and When I try to compile my test application, it doesn''t work. I get these errors: Main.cpp c:\program files\microsoft visual studio\vc98\include\gl\gl.h(1152) : error C2144: syntax error : missing '';'' before type ''void'' c:\program files\microsoft visual studio\vc98\include\gl\gl.h(1152) : error C2501: ''WINGDIAPI'' : missing storage-class or type specifiers c:\program files\microsoft visual studio\vc98\include\gl\gl.h(1152) : fatal error C1004: unexpected end of file found Error executing cl.exe. Here''s the code:

#include <iostream>
#define WIN32_LEAN_AND_MEAN
#include <gl/glu.h>
#include <gl/gl.h>
#include <windows.h>


int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
	MSG msg;
	Window currentWind (400,400,10,10,hInstance,"Ben''s Test Application");
	currentWind.Create();

	bool done=false;

	while(!done)
	{
		PeekMessage(&msg, currentWind.getHWND(), NULL, NULL, PM_REMOVE);

		if(msg.message == WM_QUIT)
		{
			done=true;
		}
		else
		{
			glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
			glLoadIdentity();

			glColor3f(1.0f,0.0f,0.0f);
			glBegin(GL_TRIANGLES);
				glVertex3f(0.0f,0.0f,0.0f);
				glVertex3f(1.0f,0,0f,0.0f);
				glVertex3f(1.0f,1.0f,0.0f);
			glEnd();

			SwapBuffers(currentWind.getHDC());

			TranslateMessage(&msg);
			DispatchMessage(&msg);
		}
	}

	return msh.wParam;
}

			SetPixelFormat(hDC, nPixelFormat, &pfd);
	}
}

PS feel free to point out horrendous code, or errors, or anything for that matter. I need criticism anyway. (I''m uber noob)

Try including windows.h before any of the OpenGL headers.
