when i put these funcions in my programme it comes up with errors like unresolved external symbol _glFinish how can i make them work. glViewport() glLoadIdentity() glMatrixMode() glFinish() also this programme open''s a gl window but i can''t quit it can you tell me how to make it so i can? #include #include #include #include #include #include int gWndID; void display() { glFinish(); glutSwapBuffers(); } void reshape( int width, int height ) { glViewport( 0, 0, width, height ); glMatrixMode( GL_MODELVIEW ); glLoadIdentity(); gluOrtho2D( -1, 1, -1, 1 );} void idle() { glutSetWindow( gWndID ); glutPostRedisplay(); } int main( int argc, char** argv ) { glutInit( &argc, argv ); glutInitDisplayMode( GLUT_RGB | GLUT_DOUBLE ); glutInitWindowPosition(0,0); glutInitWindowSize(840,680); gWndID = glutCreateWindow("Title"); glutDisplayFunc( display ); callback glutReshapeFunc( reshape ); glutIdleFunc( idle ); glutMainLoop(); return 0; } hmmm interesting

Are you linking to the opengl library ?

windows/VC++ : Project/Settings/Link and add opengl32.lib to the list

To quit, if your program is stuck, try ctrl+C in the console window or add a keyboard callback that quits if you hit escape...
