Can't Find a Project Header That is in Same Directory

[xononymous48]

I have had a project going just fine in Code::Blocks on Windows 7, but when I tried making a project still using Code::Blocks but on Linux Mint 11, I get errors saying things like "fatal error: constants.h: No such file or directory". The header files that the errors complain about are apart of my project, and are clearly in the same directory as the file including them. It doesn't do this for every header, just some. Any ideas on why this could be happening will be greatly appreciated.

Well, I figured it out. I was using source files on a shared folder between the virtual machine (Linux Mint) and my Windows host. I just relocated the source files elsewhere on the VM and it worked.
