c++ - GCC problem - invalid conversion from 'void (*)(MyObject*, bool)' to 'const void*' -

-

i don't want to, have emulate com logic in program , i'm using standard com_addref macros, keep getting following error: invalid conversion 'void ()(myobject, bool)' 'const void*'... should do?

#define com_addref(pobj, pmaster) ((pobj)->addref((pmaster), __file__, __line__, pobj))  class basecomobject { public:     inline dword addref (const void* pmaster, const char* pfilename, int line, const void* pobj) const     {         irefcount++;         return irefcount;     };      inline dword getrefcount() const     {         return irefcount;     };  private:     long irefcount; };  class myobject: public basecomobject { };  void test (myobject* pobject, bool bvalue) {     if (pobject)     {         com_addref (pobject, bvalue);// error: invalid conversion 'void (*)(myobject*, bool)' 'const void*'     } }

error: invalid conversion 'void ()(myobject, bool)' 'const void*'

error: initializing argument 1 of 'dword basecomobject::addref(const void*, const char*, int, const void*) const'

it doesn't me code that's generating error. when compile g++ (fixing obvious errors dword , modifying class state in const function, tells me can't find matching function.

the gist you're passing bool second argument com_addref , base class addref function wants void* in parameter position. highly suspect have class implicit bool constructor aren't showing us, , that's confusing compiler.

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
