i am getting a linking error when i compile the following code below. i've included all libaries and i know this code compiles as i've seen it do so on another computer, it just won't do it on mine
//================
#include <GL/glut.h>
#include <stdlib.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 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; /* ANSI C requires main to return int. */
}
//=======================
my compiler error messages are as follows:
Linking...
LIBCD.lib(wincrt0.obj) : error LNK2001: unresolved external symbol _WinMain@16
Debug/1.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
1.exe - 2 error(s), 1 warning(s)
//=========================
what i don't understand is the "error LNK2001: unresolved external symbol _WinMain@16" command line. msdev says that i need to specify an entry into wWinMainCRTStartup in the project->settings dialup box under "link". i've done this already and it still generates the error, anybody know what's going on?
i also posted this in the hardocp forum http://hardforum.com/showthread.php?threadid=73471[L=here]
