I have a windows compiler that is a derivative of cw 9.4 that is complaining when trying to compile the following #include <boost/bind.hpp> struct a { void foo(int) {} void foo() {} }; void bar() { boost::bind( &a::foo, _1 ); } the actual error is: ### mwccsym2.exe Compiler: # In: C:\Subversion\boost-RC_1_34_0\boost\boost\bind.hpp # From: bind_test.cpp # ---------------------- # 1633: ::bind_t< result_type, F, list_type >( F( f ), list_type( a1 ) ); # Error: ^ # illegal implicit conversion from 'boost::_bi::bind_t<const void (&)(void *const , const void *const , void *const , const void *const , int), boost::_mfi::dm<void (const void *const , int), a>, boost::_bi::list1<boost::arg<1>>>' to # 'boost::_bi::bind_t<const void (&)(const void *const , int), boost::_mfi::dm<void (const void *const , int), a>, boost::_bi::list1<boost::arg<1>>>' # (point of instantiation: 'bar()') # (instantiating: 'boost::bind<boost::arg<1>, void (const void *const , int), a>(void (a::*)(int), boost::arg<1>)') Changing the definition to struct a { void foo() {} void foo(int) {} }; lets it compile but this is not a general solution as this fails to compile: void bar() { boost::bind( &a::foo, _1, 0 ); } I've uploaded a full minimal example to my website including the compiler in question if it helps. http://www.mikemarcin.com/misc/mwccsym/bind_overload.zip Thanks, Michael Marcin
