Habe die Libs installiert nun stoße ich zum zweiten hinderniss:
#include <GL/gl.h>
#include <GL/glut.h>
void display (void)
{
glClear (GL_COLOR_BUFFER_BIT);
glColor3f (1.0, 1.0, 1.0);
glBegin(GL_POLYGON);
glVertex3f (0.25, 0.25, 0.0);
glVertex3f (0.75, 0.25, 0.0);
glVertex3f (0.75, 0.75, 0.0);
glVertex3f (0.25, 0.75, 0.0);
glEnd();
glFlush ();
}
void init (void)
{
glClearColor (0.0, 0.0, 0.0, 0.0);
glMatrixMode (GL_PROJECTION);
glLoadIdentity();
glOrtho (0.0, 1.0, 0.0, 1.0, -1.0, 1.0);
}
int main(int argc, char **argv)
{
glutInit (&argc, argv);
glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB);
glutInitWindowSize (250, 250);
glutInitWindowPosition (100, 100);
glutCreateWindow("GlutTest");
init ();
glutDisplayFunc (display);
glutMainLoop();
return 0;
}
Wenn ich versuche das zu kompilieren kommt:

Kann irgendjemand was damit anfangen... Habe alles genau durchgeschaut, und sehe leider keine Syntaxfehler... ☹
