I am confused by this statement:
"But no so much later there i problem within programming (some commands just don't work)."
Are you having issues with the IDE at this point, or are you having issues using the actual library at this point (pdcurses)? If the code just won't compile, please post the code sample and the compile output.
What platform are you developing on? I assume Linux if you tried QTCreator. I tried Code::Blocks under Linux a few years ago, and at the time I actually has some issues linking to libs. I then switched to Eclipse and had no issues. Anjuta looks pretty sweet as well, if you are using a GTK Desktop Environment.
How new are you to C++? If you are just starting out in programming, Python + libtcod would be a much easier.
