Hi there, for whatever reason the compiler cannot decide the right call to "make". Please consider the following code: using namespace std; using namespace boost; template< typename T > void make( const T& t ) {} template< typename T > void make( const T& t, int i ) {} template< typename T > void make( const T& t, int i, int j ) {} struct a {}; struct b {}; void foo( string& s, a ) {} void foo( string& s, b ) {} int _tmain(int argc, _TCHAR* argv[]) { string str( "Hello" ); make( ( bind( static_cast<void(*)(string&, a )>( &foo ), _1, _2)( ref( str ) , a() )) ); return 0; } I want to make a call to the first make taking just on parameter, the bind object. But the compiler thinks something else: test.cpp(29) : error C2780: 'void make(const T &,int,int)' : expects 3 arguments - 1 provided test.cpp(16) : see declaration of 'make' test.cpp(29) : error C2780: 'void make(const T &,int)' : expects 2 arguments - 1 provided test.cpp(13) : see declaration of 'make' test.cpp(29) : error C2784: 'void make(const T &)' : could not deduce template argument for 'const T1 &' from 'boost::_bi::bind_t<R,F,L>::result_type' with [ R=void, F=void (__cdecl *)(std::string &,a), L=boost::_bi::list2<boost::_bi::list_av_2<boost::arg<1>,boost::arg<2>>::B1,boost::_bi::list_av_2<boost::arg<1>,boost::arg<2>>::B2> ] test.cpp(10) : see declaration of 'make' How can I make that clear to the compiler? Thanks ahead, Christian
