OK Hopefully Someone can help.
I have Tried 3 Compilers, gcc, anjuta, kdevelop, and I get the Same thing. My GL/glut.h and the Libraries will not compile
I am Running Redhat 7.3 and I checked
/usr/include/GL/ and all is fine. Every GL Function is coming up an error.
The error is… Undefined Reference to : "Name of Function in all of My Code. I am still Learning and I am Trying to do the Soloar System Code in OpenGL Programming Third Edition, Any Suggestions? here is My Source Code…
#include <stdio.h>
#include <stdlib.h>
#include <GL/glut.h>
static int year = 0, day = 0;
void init(void)
{
glClearColor(0.0, 0.0, 0.0, 0.0);
glShadeModel(GL_FLAT);
}
void display(void)
{
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(1.0, 1.0, 1.0);
glPushMatrix();
glutWireSphere(1.0, 20, 16); //Here is the Sun 
glRotatef((GLfloat) year, 0.0, 1.0, 0.0);
glTranslatef(2.0, 0.0, 0.0);
glRotatef((GLfloat) day, 0.0, 1.0, 0.0);
glutWireSphere(0.2, 10, 8); //This is the Drawing of the Smaller Planet
glPopMatrix();
glutSwapBuffers();
}
void reshape(int w, int h)
{
glViewport(0, 0, (GLsizei) w, (GLsizei) h);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluPerspective(60.0, (GLfloat) w/(GLfloat) h, 1.0, 20.0);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
gluLookAt(0.0, 0.0, 5.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0);
}
void keyboard(unsigned char key, int x, int y)
{
switch (key) {
case ‘d’:
day = (day + 10) % 360;
glutPostRedisplay();
break;
case ‘D’ :
day = (day - 10) % 360;
glutPostRedisplay();
break;
case ‘y’:
year = (year + 5) % 360;
glutPostRedisplay();
break;
case ‘Y’:
year = (year - 5) % 360;
glutPostRedisplay();
break;
default:
break;
}
}
int main(int argc, char** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB);
glutInitWindowSize(500, 500);
glutInitWindowPosition(100, 100);
glutCreateWindow(argv[0]);
init();
glutDisplayFunc(display);
glutReshapeFunc(reshape);
glutKeyboardFunc(keyboard);
glutMainLoop();
return 0;
}
Any Help would be appreciated
Thanx in advance Guys
