Well i’ve come into a bit of trouble. I’m trying to compile one of the examples found in the redbook and I get this…
2 C:\Documents and Settings\jmcp3\Desktop\Programming\General\hello.cpp In file included from C:\Documents and Settings\jmcp3\Desktop\Programming\General\hello.cpp
43 C:\Dev-Cpp\include\GL\glut.h redeclaration of C++ built-in type `short'
C:\Documents and Settings\jmcp3\Desktop\Programming\General\hello.cpp In function `int main(int, char**)':
44 C:\Documents and Settings\jmcp3\Desktop\Programming\General\hello.cpp `GLUT_RBG' undeclared (first use this function)
I’m using Dev-C++ to compile the source, which is below.
#include <GL/gl.h>
#include <GL/glut.h>
void Display(void)
{
/* Clear all pixles */
glClear(GL_COLOR_BUFFER_BIT);
/* Draw a white polygon (rectangle) with corners
at (0.25, 0.25, 0) and (0.75, 0.75, 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)
{
/* set background color (Clearing 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_RBG);
glutInitWindowSize(250, 250);
glutInitWindowPosition(100, 100);
glutCreateWindow("Hello");
Init();
glutDisplayFunc(Display);
glutMainLoop();
return 0;
