I want to create new instance of classes FILE_ and MyParser and to pass pointer to the MyMainClass instance. But I am getting some errors. Definitions.h: #ifndef DESTINATION_CONST #define DESTINATION_CONST class MyMainClass; #endif MyParser.cpp: #include "stdafx.h" class MyParser{ private: PMainInstance * globalInstance; public: MyParser( MyMainClass * globInst ){ PMainInstance = globInst; } http://stackoverflow.com/questions/24351430/class-and-constructor-c-errors-warnings-c2146-c4430 void static ParseArgs(int argc, char* argv[]){} }; File.cpp: #include "stdafx.h" FILE_::FILE_( MyMainClass * globInst){ PMainInstance = globInst; }; main class global.h: class MyMainClass{ private: MyParser JustPars( MyMainClass ); FILE_ File( MyMainClass ); }; Now I get error on the last lines when using default constructor: error C2146: syntax error : missing ';' before identifier 'JustPars' error C4430: missing type specifier - int assumed.
