How to install OpenGL/GLUT libraries

I currently installed ubuntu 11.10 on my acer netbook. I have problem getting some packages I need. I am using the most updated version and have a wifi connection on my campus. This is what my instructor wishes for us to do:

1. select Applications/Accessories/Terminal on the Ubuntu desktop
2. type ls /usr/include/GL
   if glut.h gl.h etc are there, great
   if not, install it sudo apt-get install libglut3-dev
3. I then copied program1.c to the desktop
4. cd desktop
5. gcc -lglut -lGLU program1.cnote l is a lower-case L, which means library in UNIX
6. ./a.out to execute

I complete step 2, in which returns:

sudo: ls/brandon/include/GL: command not found

so from here I do the apt-get and try to install it but returns me with this:

E: Unable to locate package libglut3-dev

Does this have to do with my connection or is there something I need to be doing on my system for it to find the package and install it. I'm really new to ubuntu and could use some help just getting started.

Your instructions seem to be old, as far as I know glut is provided by the package freeglut3, to get it with the header files for development, install:

sudo apt-get install freeglut3-dev

freeglut3-dev

which should also pull in freeglut3.

To have found this on your own, you could have done:

sudo apt-cache search glut

After you have installed package freeglut3-dev you can confirm it contains the needed GL files by issuing

dpkg -L freeglut3-dev

which will list contents of the package which include :

/usr/include/GL
/usr/include/GL/freeglut.h
/usr/include/GL/freeglut_ext.h
/usr/include/GL/freeglut_std.h
/usr/include/GL/glut.h
/usr/lib/x86_64-linux-gnu/libglut.a
...
/usr/lib/x86_64-linux-gnu/libglut.so

To install OpenGL libraries:

sudo apt-get install mesa-utils

To install freeGlut:

sudo apt-get install freeglut3-dev

Enter the following COMMANDS using Terminal:

sudo apt-get install aptitude
sudo aptitude install freeglut3-dev

Additional Notes:If computer asks you if you accept its solution that freeglut3-dev shall NOT be installed due to dependencies, enter "n" to signify "NO".

The computer shall then notify you regarding the downgrade packages action to resolve the dependencies problem. Enter "Y" to signify "YES".

I hope this helps you too.

Thank you.
