How to run OpenGL freeglut program in Dev C++

In this article, you will learn how to run OpenGL freeglut program in Dev C++. You can create the new console base C++ project in Dev C++.

Run OpenGL freeglut program in Dev C++

Go to “file” create a new project and select console base c++ project.  Below is the screenshot

Don’t forget to add linker parameters. Right-click on the project, go to parameters, and add the linker parameters that are listed below. if you forget to add them. The project is not able to run successfully.

-lopengl32
-lfreeglut
-lglu32

Below is the screenshot of how you can add linker parameters.

Now copy the below code and paster into the project main file and run it. A red color square display on the console screen.

Program: Draw Square

//C++ OPenGL code to draw square
#include <windows.h> 
#include <GL/glut.h> 
 

void show() {
   glClearColor(1.0f, 1.0f, 1.0f, 0.0f); 
   glClear(GL_COLOR_BUFFER_BIT);       
 
  
   glBegin(GL_QUADS);              
      glColor3f(1.0f, 0.0f, 0.0f); 
      glVertex2f(-0.5f, -0.5f);   
      glVertex2f( 0.5f, -0.5f);
      glVertex2f( 0.5f,  0.5f);
      glVertex2f(-0.5f,  0.5f);
   glEnd();
 
   glFlush();  
}
int main(int argc, char** argv) {
   glutInit(&argc, argv);                 
   glutCreateWindow("OpenGL test program"); 
   glutInitWindowSize(400, 300); 
   glutInitWindowPosition(60, 60); 
   glutDisplayFunc(show); 
   glutMainLoop();        
   return 0;
}
