Hi,
i have successfully installed glut and got a sample program to compile. The source code of the program(g.cc) is as follows :

[root@kkp opengl]# cat g.cc
#include<GL/gl.h>
#include<GL/glut.h>

void display(void)
{
/* clear all pixels */
glClear (GL_COLOR_BUFFER_BIT);

/* draw white polygon (rectangle) with corners at
* (0.25, 0.25, 0.0) and (0.75, 0.75, 0.0)
*/
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();

/* don't wait!
* start processing buffered OpenGL routines
*/
glFlush ();
}

void init (void)
{
/* select clearing (background) color */
glClearColor (0.0, 0.0, 0.0, 0.0);

/* initialize viewing values */
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0);
}

/*
* Declare initial window size, position, and display mode
* (single buffer and RGBA). Open window with "hello"
* in its title bar. Call initialization routines.
* Register callback function to display graphics.
* Enter main loop and process events.
*/
int main(int argc, char** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB);
glutInitWindowSize (250, 250);
glutInitWindowPosition (100, 100);
glutCreateWindow ("hello");
init ();
glutDisplayFunc(display);
glutMainLoop();
return 0; /* ISO C requires main to return int. */
}


Now when i compile the program i get the errors listed below :

ANY sample program i try i get similar errors. I don't know what i'm doing wrong. Somebody please help me.

Thanks again

i am running Red Hat GNU/Linux 9.0

have done the glut install using glut-devel-3.7-8.i386.rpm and
glut-3.7-8.i386.rpm

if anybody can direct me to a good tutorial(one with basic sample programs) on glut(for Red Hat GNU/Linux) i'd be very grateful.

Are you sure you used -lglut for the first one? The error indicates that you used -glut, as you used in the second one.

thanks a lot for the prompt reply deiussum, i did miss 'g' while posting it . i still have the error with the -lglut and -lGL options, have given the output below. By the way have you tried programming in glut?

P.S : If there's ANYBODY out there who has successfully compiled glut programs(and gotten the desired output) please do reply.

Thanks again deiussum, i appreciate your help

Ok, now you are running into problems because you aren't linking in the GLU library, and some of the X libraries.

Also, there are some known problems with glut under RedHat. You might want to do a search on the Linux forums at http://www.opengl.org.

As a quick test, you can try adding the following libraries, though:

-lGLU -lXi -lXmu.

And yes, I've used glut. It's nice for quick little OpenGL apps, but for my final apps, I tend to use system specific calls to create the OpenGL windows.

i checked out the OpenGL GNU/Linux forum, i finally got a proper compile and the program works. Thanks a lot deiussum. i haven't got much experience in using library links in gcc, thanks to you and the guys at the OpenGL forum now i do. Thanks again.
