open GL Programming in LINUX

To compile a program (using open GL graphics library) in Linux, go to the current directory where the program is residing say test.c. type the following command gcc -o xyz test.c -lglut -lGLU -lGL -lGLU make sure you have the open GL library installed! After the execution of the command a output file with name xyz will be created in the current directory. To run the output file type in the following command ./xyz

To sum up consider a program vinod.c in the folder Graphics, to execute it perform the following steps.

administrator@ubuntu:~/Graphics$ gcc -o vin vinod.c -lglut -lGLU -lGL -lGLU

administrator@ubuntu:~/Graphics$ ./vin

Here is an example of a simple program which will just create a window with a text

#include <GL/glut.h>

void

display(void) {

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glutSwapBuffers();

}

int main(int argc, char **argv) {

glutInit(&argc, argv);

glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);

glutCreateWindow("MY FIRST GRAPHICS PROGRAM");

glutDisplayFunc(display);

glutMainLoop();

return 0;

}
