Can't get an example similar to the one found in the tutorial to work.

// ************************************* #include #include <functional>

struct X { int foo(int v) { return v;} };

int main(int argc, char* argv[]) { boost::function1 f; X x; f = std::bind1st ( std::mem_fun(&X::foo), &x ); f(5); // Call x.foo(5) return 0; }

//***************************************

I get this error message: : error C2784: 'class std::mem_fun_t<_R,_Ty> __cdecl std::mem_fun(_R

(__thiscall _Ty::*)(void))' : could not deduce template argument for '<Unknown>' from 'int (__thiscall X::*)(int)'

I believe this is actually a bug in the standard library that ships with MSVC 6.0. I suggest you use Boost.Bind instead: f = boost::bind(&X::foo, &x, _1); Doug
