I use Linux Mint 14 and loaded Codeblocks 10.05 using the software manager.
Using a console application no problems, so I tried to use a wxWidgets project, here I found that I could create a project but when I came to build it had errors which pointed to missing headers. /wx/*.h many people seem to have had this error on the forums. I went into the Synaptic package manager and downloaded and installed wx2.8 headers. When I had done this all was well and I can now build and compile GUI apps, no more missing header errors or setup.h errors.
I assume as I could not find the wx folder referred to in the build errors that these did not install with Codeblocks 10.05 when it was first installed.
I have included this in case it may help someone using Codeblocks with Linux.
