Hi, Visual Studio 2005 gives me warning C4180 ("qualifier applied to function type has no meaning; ignored") when binding member functions that has a templatized type as return type with boost::bind, but I can't see any reason why it should. The following example reproduces the warning: #include template <typename T> struct Foo {}; struct Bar { Foo<void> f() { return Foo<void>(); } int g() { return 0; } }; Foo<void> f() { return Foo<void>(); } int main(int argc, const char **argv) { Bar b; boost::bind(&Bar::f, &b); // Warning C4180 (see below) boost::bind(&Bar::g, &b); // No warning boost::bind(f); // No warning return 0; } So far as I have tested, the program appears to function properly. The full warning is as follows (paths shortened): C:\...\boost/bind.hpp(1575) : warning C4180: qualifier applied to function type has no meaning; ignored C:\...\boost/bind.hpp(1609) : see reference to class template instantiation 'boost::_bi::add_cref' being compiled with [ Pm=Foo<void> (__thiscall Bar::* )(void), I=1 ] ..\..\..\src\main.cpp(14) : see reference to class template instantiation 'boost::_bi::dm_result' being compiled with [ Pm=Foo<void> (__thiscall Bar::* )(void), A1=Bar * ] GCC 4.1.2 on Linux compiles the code without warnings. Any insights are greatly appreciated! Best regards, Josef Grahn
