getting video tutorial rocks game running on ubuntu linux

My 8 year old  has been wanting me to write a computer game for here for some time.
I’m currently taking a second course in c++ and I do need the practice so what the heck.

I found this most excellent guide at: http://www.videotutorialsrock.com/opengl_tutorial/crab_pong/home.php

I thought perhaps I could hack up the code and getting it running in Ubuntu
So… I downloaded the source and created a code::blocks project and the first message error I get is this:

Hm… Soo lets hack away at the errors:

I did a quick search and found this info: http://ubuntuforums.org/showthread.php?t=1108737

Ok..

I’m pretty sure I have the required libraries but I think I’ll try this

Ok… So I’m missing something the dev

Soo… Now I left with these error.

Hmm.
According to http://www.cplusplus.com/reference/clibrary/cstring/strlen/

I need to #include <string.h> so I added that to the top of md2model.cpp.  (Not sure if thats the best spot but lets see what happens.)

Uggg… We’re not there yet… Now I get this.

I got myself confused with the code:blocks linker settings and I wound up asking for directions before I figured out what was going on.
http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=292961&#Post292961
and
http://ubuntuforums.org/showthread.php?t=1701528
Anyway.. the linker settings in code::blocks need to be as follows:

-lGL -lGLU -lglut

As you can see.  I got it work.

Now, I need to study how this ticks and see if I can hack it up a bit to turn it into a game for my kid…
