[Maybe a bit OT] Opengl GLSL on windows

SDL Development
1

Hello,

I found some thread on opengl 1.2+ on windows, but nothing up to date.

My question is simple, actually, I compile my game on macosx intel
and ppc.

To compile the windows version, I use mingw with the SDL include
files I found here:
http://www.libsdl.org/extras/win32/common/opengl-devel.tar.gz

But they seem to be outdated.

Also, I downloaded the:
w32api-3.6.tar.gz
(actualy build-cross.sh did it)
but it contains only 1.1 opengl implementation.

So, I think I must find updated gl.h and glu.h, and also a lib with
the function in them.

So, to summarize:

  • Where to find those files?
  • What do you think of using opengl 2.0 on windows and GLSL?

I know those questinos are a bit OT, but as I dev with SDL, and as I
can compile my app on windows because I use SDL, I thought it would
be cool to have this discussion here as others might be helped.

This is the horror that is OpenGL on Windows.

Read http://www.gamedev.net/reference/programming/features/oglext/ it
seems to cover the basics (I learnt elsewhere).

If I remember correctly, OpenGL applications on windows are supposed to
only link to OpenGL 1.1-features, functions from newer OpenGL-versions
should be loaded as extensions.

This is mentioned in the comments in gl.h and glext.h from the w32api
package.

So, include gl/glext.h in order to get the necessary defines, and load the
symbols using SDL_GL_GetProcAddress.

Hello Kuon,

Basically, MS haven’t updated the headers or ICD system since OpenGL
1.1. You have to get advanced features through extensions.

You might want to look at GLEW http://glew.sourceforge.net/ - this
will work cross-platform and should help.–

Glew solved it. Thanks much.
