custom signals vs newbie

[wysota]

I'll try to explain what the problem is and maybe you'll find a solution yourself without showing us all the code

The compiler thinks void result(...) is a declaration of a variable and not a function. It might be because there is something wrong with "EViewport" or because the compiler is confused by some earlier error (that's why I asked about viewports.h). You can try removing the signals: keyword and check if the problem persists.

Ok, fixed, just for change you were right again

No, signals: cut out made no difference.
The problem was that in viewports.h I included manager.h (the error file), but the definition of EViewport came after the manager inclusion, so:

// viewports.h
#include "manager.h" // manager.h still doesn't know EViewport, so raises error
enum EViewport{
      [...]
}

// viewports.h
#include "manager.h" // manager.h still doesn't know EViewport, so raises error
enum EViewport{
      [...]
}
