Code::Blocks

I made a Code::Blocks project file for HeeksCAD.
I used this on my Dell Inspiron 530 running Ubuntu 9.04.
It works for me. I can edit a file, press "Build" and it only builds the file it needs to.
I can do "Find Declaration of" or "Find Implementation of".
I don't seem to be able to add breakpoints while it's running. I seem to have to add them before I start running.
