new types may not define a return type - C++

Question：

I am confused I think on C++ class structure.

I have a .h called FxMathFunctions.h and a .cpp called FxMathFunctions.cpp

the .h starts like:

class  FxMathFunctions{    public:        FxMathFunctions();        ~FxMathFunctions();

and in the .cpp

I have:

#include "FxBasicTypes.h"#include "FxMathFunctions.h"FxMathFunctions::FxMathFunctions() {}FxMathFunctions::~FxMathFunctions() {}

I am getting errors like:

error: new types may not be defined in a return typeerror: return type specification for constructor invalid

This must be something to do with definition someplace, but I just dont see where this might occur

Answer：

What does your .h file end with? I'm guessing that the end of your class defnition does not have a ";". The class is being interpreted as the return type of the first function in your cpp file.
