Replacing GLEW about edge

[usernameak]

I think that custom implementation is the best way 😃

[Corbachu]

I was thinking about that, too: any ideas where we could start with that? I have always used external loaders..

[usernameak]

What methods of GLEW are used?

[Corbachu]

Look in r_main.cc:

RGL_CheckExtensions() is the function that finds and appends all functions (which, really, isn't a ton...)

[Corbachu]

I am also looking into dGLMake from Doom64-EX, so hopefully I can get on that soon!

Is 3dge still using GL/glew.h really? I noticed at least in i_video.cc i can comment out the include for GL/glew.h and it seems to affect nothing...

[Corbachu]

I will test this out tonight. The i_video code now uses sdl_opengl, but GLEW is still required for extension checking. We really need to get a replacement going..

[usernameak]

On Linux it's easier: just make a header
On Windows we need to use wglGetProcAddress

[Corbachu]

Want to revisit this issue soon :)

[Corbachu]

Opened up a new branch called "noglew", it uses GZDoom's version of glLoadGen. If anyone is curious. As soon as I get it working properly consider GLEW as good as gone :-D

[Corbachu]

@usernameak Maybe you can help me test it out? Just checkout noglew to see where it stands right now. :-)

[Corbachu]

We have successfully stripped out GLEW for our own implementation (based off of GZDoom). Closing this finally :)
