}automated extension linking with GLee (V1.1 is up)

Edit: Version 1.1 is up. It's a bit neater internally, and it gives detailed error reporting (see the readme).
I've just finished writing GLee, the OpenGL Easy Extension library. It's developed using a little program I made called GLeeGen, which automatically writes the code to link and query every OpenGL extension based on the contents of glExt.h and wglExt.h. As far as I know, it supports every GL and WGL extension in the registry.
To use it, you just have to link to glee.lib, and include glee.h in your project. Once linked, it's pretty straightforward to use:
Congrats on finishing this, but I thought I should let you know that there is already a library that does what yours does... at least from what you''ve put down so far. Have you heard of Lev Povalahev''s extension loading library? Take a look at it if you haven''t. Maybe you could post what makes yours unique or different.

I'm aware of other similar libs such as extgl, GLEW and GLuX.
The main advantage of my lib is it supports every extension in the registry. It's automatically generated, so every extension in glext.h and wglext.h is supported as soon as glext.h and wglext.h are updated; I just have to run GleeGen.exe and rebuild. I believe GLEW works in a similar way, however the licenses are more restrictive.
I plan to support it right up through OpenGL 2.0 and beyond.

others don''t need it as well.. dunno.. it would look much more clean.. and as i use sdl i normally don''t access the hdc myself at all..
wglGetCurrentDC or so should give you all you need, not?

Ah, wglGetCurrentDC, that's what I needed. I was looking in the win32 API docs before. Thanks. It's fixed now.

Cool! I''m using extgl for my projects right now, but I''ll give it a try. Also, maybe it would be helpful to add links to your libray and extgl as well as others to the forum faqs, since every so often there are questions on good ways to load extensions.
