We all know that Bullet doesn't come with precompiled libs so we need to make them ourselves

First step is to download Bullet Physics Library from http://code.google.com/p/bullet/downloads/list

after you downloaded it you extract it to the place you want(if you download the .zip version)
and then we open GCC Code::Blocks and go to "file->new->project" and a pop up opes and we choose "Static library"


and then put the project title you want and folder you want it to be in(you know like you do with other projects)
the "Static Library" crates a main.c...remove that file

and then right click on the project name and choose "add files recursively" and then choose the "src" folder inside the bullet folder(the folder you extracted bullet in)

click OK and click "select all" and click OK
if everything looks like this then your on the good path

then right click on the project name and choose "build options" and a pop up should appear

then go to the search directories and add the bullet "src" folder and the "Bullet\src\BulletMultiThreaded\vectormath\scalar\cpp" folder
then click build and it should build successfully.
go to the folder you have your project in and you should get a ".a" file..that's the bullet lib...
This tutorial has been written by Lil_Margin and if its good enough i would like if it could be added to the Bullet wiki so i can contribute to bullet wiki

Have a good day ladies and Gentleman.
