Hi,
I'm attempting to compile this code from nehe:

GLvoid InitGL(GLvoid);
GLvoid DrawGLScene(GLvoid);

int main(int argc, char** argv)
{
	
    glutInit(&argc, argv);
    glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB | GLUT_DEPTH);

    return 0;
}

GLvoid InitGL(GLvoid)

    gluPerspective(45.0, (GLfloat) Width / (GLfloat) Height, 0.1, 100.0);
   
    glMatrixMode(GL_MODELVIEW);
    glLoadIdentity();
}

I updated the libraries with their correct paths
#include <OPENGL/gl.h>
#include <OPENGL/glu.h>
#include <GLUT/glut.h>

The code compiles and links but upon executing it fails with

Code:

asddd has exited due to signal 6 (SIGABRT).
[Session started at 2006-08-01 23:01:04 +0100.]
ZeroLink: unknown symbol '_glutInit'

I suspect the problem is with the glut.h framework, any suggestions? Thanks in advance.

You included the OpenGL framework right?

And if I remember correctly, you don't need to include GLUT (it's been a while since I've dabbled in OpenGL).

The code doesn't link. Turn off ZeroLink and you'll get a link error when you build the project.

Make sure you added the GLUT framework to your project. If you did add the GLUT framework, try adding the Cocoa framework to your project. GLUT is written in Cocoa. I'm not sure what version of Mac OS X you're using, but some older versions required you to add the Cocoa framework to build GLUT applications. I don' use GLUT so I'm not sure if you still need to add the Cocoa framework, but it's something to try.

If you still can't get the code to build, take a look at SDL. It is a cross-platform game library that does everything GLUT does. If you click the link in my URL you can read an article I wrote on using SDL with OpenGL. The article includes a simple program that creates a window and draws a colored rectangle in the window. You could take the OpenGL code from the NeHe tutorial and add it to my program, making sure not to add the GLUT code.
