gcc … -L/usr/X11R6/lib -lGL -lGLU -lglut
and i get errors like" undefined reference to glXQueryExtension" ect…
hmm i really dont know whats wrong. Any help would be appriciated.

Could you copy and paste the exact command line you use and the exact errors you get?
From what you posted it looks like you’re doing everything OK.

thats what happens when i compile heres the program.
<code>
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
#include <GL/glut.h>
#include <stdlib.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)
{
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutInitWindowSize(250,250);
glutInitWindowPosition(100,100);
glutCreateWindow(“hello”);
init();
glutDisplayFunc(display);
glutMainLoop();
return 0;
}

That’s pretty odd. What distro are you using?
You might try:
-lglut -lGLU -lGL
or
-lglut -lGLU -lGL -lX11
or
-lglut -lGLU -lGL -lXext -lX11
Let me know which one works
using mandrake 7.2
in the first one i got different/more of the same errors
the second/third user/bin/ld "cannot find -lX11
and in the fourth " cannot find -lXext
Strange.
I also use Mandrake 7.2, and all I need is
the following:
-L/usr/X11R6/lib -lGL -lGLU -lglut
Couldn’t find -lX11??? That’s not good… it should be in /usr/X11R6/lib, which you specify on the command line.
Uhm… what do
$ rpm -q XFree86
and
$ rpm -q Mesa
tell you?
thanks alot for your help
i got it working…i reinstalled xfree86-dev pkg and now iv got my hello box.
thanks again
