I've working my way through the ogre tutorials and tried to build my own code::blocks project rather than using the cmake system.
I ran into this weird situation that I don't understand. Here the build log.

The first complaint is that about a timestamp... What's the deal with that??
I renamed the file and create a new main.cpp, cleaned the project and yet this still persists. Permissions seem ok.

I don't think I've screwed anything with the structure with the code, which has me really befuddled why this mult defination of main thing is occurring.
Is the time stamp thing hosing something up with the linker?? Or am I'm doing something stupid here(which is what I suspect)? I could use some pointing in the correct direction.
(Btw... using SVN 7154 Build: May 21 2011 -wx2.8.10 (Linux,unicode)-32bit
I had created a new Ogre project and I deleted the main.cpp and then included my in a seperate folder. It appears that there was some residue left over

When I manually deleted "<Unit filename="main.cpp" />" everthing worked fine. It appears that when the file was removed from the project via the code::blocks gui, this line was not removed from the list. (Is this a code::blocks bug that needs to be reported?)
