Having problems with OpenGL and extensions.

[indigo0086]

I'm trying to do an example with Buffer objects which were intdocued in 1.5, meaning I have to access them with extensions. I am using the glew library and it says I have support for opengl 20. Whenever I try to call glGenBuffers() it just doesn't work. After I call glIsBuffer() on the GLuint I passed to glGenBuffers() it doesn't come out at all. Do I have to do something else with the extension to get it to work? I tried to check to see if it was supported but can't seem to find it in the mass of enumerated variables for the extensions.

Make sure your GLuint is a pointer passed by reference (that is what it's called, right? ie glGenBuffers(1, &myBuffer)) to glGenBuffers. You could also try using glGenBuffersARB(), just in case. Although I'm pretty sure GLEW should be getting the 1.5 version.

I did that, I called it like

    GLuint buffer;
    glGenBuffers(1, &buffer);

    if(glIsBuffer(buffer) != GL_TRUE)
    {
        std::cout << "buffer did not initiate" << std::endl;
        glfwTerminate();
        return 1;
    }

Do I have to enable something first?

edit: I also tried glGenBuffersARB with no avail.

Do I have to do any of the function pointer stuff with glew?

Nope, GLEW should handle the function pointer stuff. The only thing you have to make sure you do is call glewInit().

If GLEW wasn't getting the function properly, you'd probably be crashing with an access violation.

What graphics card is this running on?

[indigo0086]

Radeon x1950 Pro. Though I'm not using catalyst drivers, as they render all my opengl Applications useless (they crash while OS gets the window context). I'm using the Omega Drivers. They've since released 7.8, but I don't even want to go through the hasstle as I've been over tech support over a week and they were useless. I can skip over the buffer example, but I just am worried how other extensions will be handled when I meet them.

Ahh, I need to read more carefully, glIsBuffer returns true if buffer object has been bound.
