Compile cant find QMainWindow

[thomasGl]

Hello guys. I am trying to compile a programm with g++ and it cant find QMainWindow. Where can i find this file?

Are you running the command from the same directory? Can you see the file in the output when you run ls?

Also why do you need to compile it manually?

@thomasGl hi,

Your command is missing all the include paths and libraries options to properly build your application.

You should either use qmake or CMake (recommended) to manage that part.

How can I use memcheck? It doesn't start.

I wanted to do it manually because I wanted to use Valgrind to find memory leaks.
