Hello, I’m new to OpenGL and I just bought the “redBook”. I tried the first program: hello.c (see code below) and when I try to compile (with dev-C++ and the .NET framework[c++ compilers]) and it works, but for some reason it won’t link.
Note that I tried to add #include<windows.h>, since I have windows, #include<GL/gl.h> and #include<GL/glu.h>, but it still didn’t work.
#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, 0.25, 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)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutInitWindowSize(250, 250);
glutInitWindowPosition(100, 100);
glutCreateWindow("hello");
init();
glutDisplayFunc(display);
glutMainLoop();
return 0;
}
Thank you for your answers.
