Compilation QT Creator project using classic terminal and gcc/g++

I'm tired searching in internet. I created a klient-serwer program, which shut down computer just by their IP's on specific port.I made whole thing in C, everything works perfectly, i'm compiling my project using gcc with -Wall option and I've got a clear results. But I had to create GUI so i decided to use QT Creator IDE, I transfered code from C into C++ and i made GUI. Program works but I have to compile this using g++ with -Wall option. Thing is, I cannot compile anything.

g++ my_project.cpp -o mypro -Wall

ERROR: fatal error: QMainWindow: directory don't exist (in my native language)
compilation terminated
(same with other source files)

Any ideas? It's propably very easy, but believe me, I want to compile this and go to sleep. Cheers

Why don't you use qmake? First, you can edit your *.pro file and add any compiler flags you wish (see Mitch's comment). Then, if you execute qmake and then make, it will show you a sequence of compilation commands with proper flags, linker and include paths and so on. After that you can just reproduce that commands manually if your teacher wants so.

The error shows that the compiler is trying to open QMainWindow as if it was a directory (if the translation is correct) or at least failing to locate where the include files for Qt are. You probably need to provide some -I option to hint the compiler as to where the Qt headers are, and make sure that the #include directives are correct in your code.
