Hi,
i wanted to set up a ogl scene with this tutorial (http://www.sfml-dev.org/tutorials/1.6/window-opengl.php), but i always get the error message: "use of undeclared identifier" for every ogl function. i use xcode 4.
i also tried including <OpenGL/OpenGL.h> but it changes nothing.

Code: [Select]

 
    // Set color and depth clear value
    glClearDepth(1.f);
    glClearColor(0.f, 0.f, 0.f, 0.f);
    
    // Enable Z-buffer read and write
    glEnable(GL_DEPTH_TEST);
    glDepthMask(GL_TRUE);
    
    // Setup a perspective projection
    glMatrixMode(GL_PROJECTION);
    glLoadIdentity();
    gluPerspective(90.f, 1.f, 1.f, 500.f);

Can you show your complete source code and the exact error messages?

Oh, you're using SFML 2. You should have said it

Include <SFML/OpenGL.hpp>.

And don't hesitate to look at the provided examples, there are two that use OpenGL.
