Thanks for your reply Obfuscated,
No, I havent this line nowhere in Project>Build options.
Instead of this I have `pkg-config gtk+-2.0 --cflags` at Compiler settings>Other options
Where exactly I should add this line?
I didnt try wxWidgets template yet.
Actually, I dont know how and where they are.
I just want to fire any (simplest) gui to start teaching about this area.
But it goes wery hard.
If you can please explain me in few clear steps how to get "anything".
I started to learn c++ 1 month ago.
This goes well but GUI dont go yet...
