This is my old system where my program compiles just fine:

This is the error I get:

It seems like it fails compiling as soon as I include anything Q* in a .cpp file. Even if I remove the statements from src/controller.cpp, a similar error gets thrown in the next file where I include Q*. In it's always "initializer provided for function". A new project compiles fine and I can't pinpoint anything that causes the error in my project. Does anyone have an idea what causes the problem? I'm pretty desperate at this point, any help will be appreciated. I can also upload the source files if the error is too ambiguous.
