Question

I’m working with an example from this site on OSX and I have no troubles compiling it but I don’t know how to test run it. The program looks like this:

void display()
{
}

int main(int argc, char **argv)
{
        glutInit(&argc, argv);
        glutDisplayFunc(display);
        glutMainLoop();
}

I don’t know what the arguments should be for the program, which glutInit will use. Does anybody know what with which arguments I need to call me program to acually show a window?

Calling with no arguments orcourse causes this crash:

./hello

Abort trap

Answer 1

You need to create a GLUT window before calling glutDisplayFunc or glutMainLoop
