newbie openGL question

Hi there. I’m trying to get back to doing some openGL programming but have come across a rather annoying and confusing problem

After I compile a program I’ve written (Borland bcc32 if that’s important) and try to run the .exe, I get a ’ test1.exe has encountered a problem and needs to close. We are sorry for the inconvenience’ error with windows asking if I want to send an error report (to who… me?). I assumed it was my programming ineptitude so I tired opening a simple exe (just opens a blank window) and the same error pops up. I don’t know what to do.

Any help you guys could give would be great.

Here’s the code. It’s as simple as I could make it to test that opengl works

#include <windows.h>
#include <GL/glut.h>
#include <stdio.h>
#include <stdlib.h>

void init ( void ) {
glEnable ( GL_DEPTH_TEST );
glClearColor ( 0.0, 0.0, 0.0, 0.0 );
}

void display ( void ) {
glClear ( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
glutSwapBuffers ( );
}

void reshape(int w, int h) {
glViewport ( 0, 0, w, h );
glMatrixMode ( GL_PROJECTION );
glLoadIdentity ( );
if ( h==0 )
gluPerspective ( 80, ( float ) w, 1.0, 5000.0 );
else
gluPerspective ( 80, ( float ) w / ( float ) h, 1.0, 5000.0 );
glMatrixMode ( GL_MODELVIEW );
glLoadIdentity ( );
}

void keyboard ( unsigned char key, int x, int y ) {
switch ( key ) {
case 27: /* Escape key */
exit ( 0 );
break;
case ‘f’:
glutFullScreen ( );
break;
case ‘w’:
glutReshapeWindow ( 250,250 );
break;
default:
break;
}
}

int main ( int argc, char** argv ) {
glutInit ( &argc, argv );
glutInitDisplayMode ( GLUT_RGB | GLUT_DOUBLE );
glutInitWindowSize ( 250, 250 );
glutCreateWindow ( argv[0] );
init ( );
glutReshapeFunc ( reshape );
glutKeyboardFunc ( keyboard );
glutDisplayFunc ( display );
glutMainLoop ( );
return 0;
}

Cheers.

I don’t use borland, so I can’t speculate on problem areas in your environment. But the code you posted shouldn’t generate any runtime exceptions.

It seems there are others that are having trouble with borland and opengl…

P.S. You need to specify a depth buffer if you want to use the depth test (GLUT_DEPTH).

Thanks for that. Sorted it out myself yesterday. I stupidly put the *.dll’s in c:\windows\system when they should have been in c:\windows\system32, so borland couldnt find them i guess.
