I'm trying to get OpenGL to work with SDL and I've set up SDL so that it works and so that I can use it, but the thing is that I can't get OpenGL to work.
I want to use OpenGL to render and SDL to do all of the other stuff (SDL_opengl). I've linked to SDL, but when I write anything related to OpenGL in my code, I get linker errors when I compile the application.

Ex:

"1>main.obj : error LNK2019: unresolved external symbol __imp__glEnd@0 referenced in function "public: void __thiscall Player::show(void)" (?show@Player@@QAEXXZ)"

I guess I have to link to OpenGL as well, but the thing is that I don't know how to do that, I've tried with 'SDL_opengl', '-lopengl32', 'lopengl32', 'opengl32' and so on, but then I get the error "can't open opengl32.obj".

Is the problem that I have to link to OpenGL as well and if so, how do I link it and do I need to download any additional OpenGL files?

isn't it opengl32.lib and glu32.lib

Lol, I feel so stupid. Thank you, it worked

I am having a similar issue too. I am wondering how to get opengl to do all my rendering and use sdl for sound, but for some reason sdl wants to take over. Have you figured out how to do that?

Yes I have. I'd recomend you to have a look at this tutorial: http://lazyfoo.net/SDL_tutorials/lesson36/index.php
If you just want a short answer from me, you basically just add the constant "SDL_OPENGL" in the 'SDL_SetVideoMode' funtion for example like so: "SDL_SetVideoMode( x, y, 32, SDL_OPENGL )" You can also add other parameters if you wish to by using the bitwise OR symbol (|) like so: ( SDL_OPENGL | *Other constants* )

Hope that answered you question
