How to Install OpenGL on Ubuntu Linux

 

What Is OpenGL?
OpenGL is a Graphics rendering API which is operating system independent, window system independent and has high-quality color images composed of geometric and image primitives.
OpenGL APIs can use following …

• Gl
  • OpenGL API implementation (http://www.opengl.org)
• Glu
  • OpenGL Utility
• Glut – GLUT (OpenGL Utility Toolkit) – Glut is portable windowing API and it is not officially part of OpenGL.
  • OpenGL Utility Toolkit (http://www.opengl.org/resources/libraries/glut/)
• FLTK
  • FlashLight ToolKit (http://www.fltk.org/)
• GLEW…

Now lets see How to install OpenGL on out Ubuntu OS.

Now because GLUT (OpenGL Utility Toolkit) depends upon OpenGL and a number of other related libraries, if we install GLUT then OpenGL will be automatically be installed.

Run the following commands to install OpenGL.

$ sudo apt-get update $ sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev

1 2	$ sudo apt-get update $ sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev

Now to test if OpenGl libraries are working fine on our Linux, we will create a C++ program and test it.

So create a following C++ Program.

#include <GL/glut.h> void displayMe(void) { glClear(GL_COLOR_BUFFER_BIT); glBegin(GL_POLYGON); glVertex3f(0.5, 0.0, 0.5); glVertex3f(0.5, 0.0, 0.0); glVertex3f(0.0, 0.5, 0.0); glVertex3f(0.0, 0.0, 0.5); glEnd(); glFlush(); } int main(int argc, char** argv) { glutInit(&argc, argv); glutInitDisplayMode(GLUT_SINGLE); glutInitWindowSize(400, 300); glutInitWindowPosition(100, 100); glutCreateWindow("Hello world!"); glutDisplayFunc(displayMe); glutMainLoop(); return 0; }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

#include <GL/glut.h>   void displayMe(void) {     glClear(GL_COLOR_BUFFER_BIT);     glBegin(GL_POLYGON);         glVertex3f(0.5, 0.0, 0.5);         glVertex3f(0.5, 0.0, 0.0);         glVertex3f(0.0, 0.5, 0.0);         glVertex3f(0.0, 0.0, 0.5);     glEnd();     glFlush(); }   int main(int argc, char** argv) {     glutInit(&argc, argv);     glutInitDisplayMode(GLUT_SINGLE);     glutInitWindowSize(400, 300);     glutInitWindowPosition(100, 100);     glutCreateWindow("Hello world!");     glutDisplayFunc(displayMe);     glutMainLoop();     return 0; }

Now give the command below to compile your code.

$ g++ main.cpp -o firstOpenGlApp -lglut -lGLU -lGL

1	$ g++ main.cpp -o firstOpenGlApp -lglut -lGLU -lGL

Now run your OpenGl program with following command

$ ./firstOpenGlApp

1	$ ./firstOpenGlApp
