Find declaration / implementation in debian

[yakumoklesk]

I cannot make it work to find a simple wxFrame declarations. It says it is not found. I've added to the C/C++ directory search the path "/usr/include/wx2-8", also to the compiler settings in search directories, restarted, and nothing. Everything goes ok on XP and Vista, but cannot make it work on linux.

Any hint? Do I need to define the wx global variable? Everything builds well without it.

Thanks in advance.
