I've been following the NeHe OpenGL tutorials and have gotten as far as loading TGA images and converting them to textures. Everything goes well - the loader works fine - but I don't know how to actually make use of the texture.
I can't use glBindTexture (GL_TEXTURE_2D, Textures[0]); because the second argument isn't a GLuint (it's a user defined struct "TGAImage").
The most annoying thing is he's shown you how to load the TGA but not how to use it - can anyone help me?

you can use allegrogl to load a tga and then 'allegro_gl_make_texture()' to convert into GLuint .

Thanks I'll have a look at that now.
Are there any other options or is allegrogl my best bet?

OpenIL AKA DevIL library is an easy cross platform option.
>because the second argument isn't a GLuint (it's a user defined struct "TGAImage").
You need to pass the GLUint returned as the second argument of glGenTextures(). You'll need to store that in your struct if its not there already.
Thanks I've figured it out now

Just to let you (and anyone else having similar problems to me) OpenIL is the path I would recommend. Really easy to setup (I copied the libs / headers to my OpenGL dirs for clarity) and using the library is really easy to pick up. If anyone needs a start: http://gpwiki.org/index.php/DevIL:Tutorials:Basics
Thanks for that sand_man
