Installed open GL on ubuntu 16.04. where is the program

What is the test program?
Do 3D games run OK (Super Tuxcart is one example)

The test program is below

#include <GL/glut.h>

//Drawing funciton
void draw(void)
{
  //Background color
  glClearColor(0,1,0,1);
  glClear(GL_COLOR_BUFFER_BIT );
  //Draw order
  glFlush();
}

//Main program
int main(int argc, char **argv)
{
  glutInit(&argc, argv);
  //Simple buffer
  glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB );
  glutInitWindowPosition(50,25);
  glutInitWindowSize(500,250);
  glutCreateWindow("Green window");
  //Call to the drawing function
  glutDisplayFunc(draw);
  glutMainLoop();
  return 0;
}

When I try to compile the abv program , I get the following msg:
gcc testG.c
/tmp/ccQ9Iq5n.o: In function `draw':
testG.c:(.text+0x2b): undefined reference to `glClearColor'

testG.c:(.text+0xb6): undefined reference to `glutDisplayFunc'
testG.c:(.text+0xbe): undefined reference to `glutMainLoop'
collect2: error: ld returned 1 exit status

I assume that the OpenGL programs are not correctly installed.

Please help me.

Thanks

Does a command like

gcc testG.c -lGL -lglut

produce the same error messages, or something different?

Does a command like

gcc testG.c -lGL -lglut

This command works with no errors.

Thank you for the help.

My question is where is ligglut and libGL.

When I search for them I get the following:

tkn@tkn-ET1810:~/Desktop/test$ whereis libglut
libglut:
tkn@tkn-ET1810:~/Desktop/test$ whereis ligGL
ligGL:
tkn@tkn-ET1810:~/Desktop/test$

I require these libraries in the /usr/lib folder to install another program.

Thanks for your help.

It seems that you are not aware of the directory structure for shared libraries.

Depending on your architecture the libglut and libGL files are in
/usr/lib/x86_64-linux-gnu/
or
/usr/lib/i386-linux-gnu/

Instead of copying them to /usr/lib you should add the correct compiler and linker options (like -lGL -lglut).

And by the way, the libglut and libGL files are not executables, but shared libraries. So you cannot expect to find them with the whereis command which is a command to search for executables and man pages.
