hi all..

when i try to compile this program gcc return this list of 'errors'..

this is a piece of the source code..
<code>
#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();
...
</code>

this the errors list 
<errors_list>
/tmp/cc3aHpJh.o(.text+0xf): In function `display':
: undefined reference to `glClear'
/tmp/cc3aHpJh.o(.text+0x2c): In function `display':

/tmp/cc3aHpJh.o(.text+0xb5): In function `display':

the linker cannot resolve the references to the gl-functions.
try linking against libGL.

like "gcc test.c -lGL"
