Begginer needs help

[masigor]

Hi,I am new to openGL.I have downloaded glut 3.7.6(compiler dev c++ 4.9.9.2,system Windows XP). I try to compile this code(first tutorial):

#include <GL/glut.h>
void init()
{
glClearColor(1,0,0,1);
glOrtho(0,1,0,1,0,1);
}

void display()
{
glClear(GL_COLOR_BUFFER_BIT);
glFlush();
}

void main(int argc, char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_RGB|GLUT_SINGLE);
glutInitWindowSize(800,600);
glutInitWindowPosition(5,20);
glutCreateWindow("Tutoral 1");
init();
glutDisplayFunc(display);
glutMainLoop();

}

and recived this linking error:

Goto project options and find the field 'Linker' (or of a similar name), and add this to it:

-lopengl32
-lglu32
-lglut

Those should link to all the libraries you will use

[masigor]

It works.I have added this to 'Linker' project options: -lglut32 -lglu32 -lopengl32 -lwinmm -lgdi32.Thank you!!!

No probs - I've used devc++ for a cross-platform project of mine and have minor experience with it.
