I'm using Code::Blocks compiler, and found that there is a bug regarding old versions of wxGTK (That caused the program to crash). I'm not sure how to upgrade, but on the wxWidgets Web site it said to add this:
deb http://apt.tt-solutions.com/ubuntu/ dapper main

However I don't really know what it means. I tried just going to that url and it had several .deb packages. I would be grateful if someone could assist me in upgrading my wxGTK to version 2.8.4

Thanks,
David
