   OpenGL Header Files
  Hey I recently found a pretty good OpenGL tutorial that I would like to dabble a little bit in while imlearning C++. However in the examples they use these header filesGL/gl.hGL/glut.hI tried installing OpenGL but it keeps giving me the error that it can't not find these header files. I looked in my header file folder and I don't see them anywhere either. If anyone could tell me how I could get these. I would appreciate it.   
  You don't mention what development environment you're using on which platform but I'm fairly sure that for MSVC++ Express 2005 you get it with the platform SDK.   ;  Sorry, Im using Dev-C++ on Windows XP. I just don't know where to get these header files from.   ;  GL/gl.h is how Linux includes the gl.h header. On Windows use the following statement:#include <gl.h>Pzc is right. The OpenGL headers and libraries are part of the Windows Platform SDK.Mark   ;  Oh ok, I was able to get the glu.h file but I can not find the gl.h file.What is this Windows SDK? Something that comes with OS or something I have to download?   ;  Dont use Dev-c++. Its old and outdated. Download Microsoft's Visual c++ Express. Then look for the "Windows sdk", and search around on how to install it, and youll be ready to go.   ;Quote:Original post by CarlosNYM...What is this Windows SDK?

Here's a link to page on MS where you can download their free Express editions, a bit further down they link to the Platform SDK.Clicky !;  for the windows SDK,  just goto microsoft.com and search "Windows SDK" i believe you'll be looking for the R2 version from what i remember
