I'm trying to use g++ (and MinGW) to compile a win32 Direct3X program
that I've written under Visual C++. All is well (so far) except for one
thing.
I'm using the technique suggested in the Boost shared_ptr documentation
to store pointers to COM objects, which works fine under Visual C++ but
under g++ (either 3.4.x or 4.3.x) I get errors about the call to mem_fn
being ambiguous due to stdcall / non-stdcall overloading.
I can't find any references to this problem on the net so I assume I'm
doing something utterly boneheaded. Any hints would be very welcome.
For example:
#define BOOST_MEM_FN_ENABLE_STDCALL
#include
#include
#include
void test_mem_fn(IDirect3DDevice9 * const device)
{
boost::shared_ptr<IDirect3DDevice9> ptr(
device,
boost::mem_fn(&IDirect3DDevice9::Release) );
}
test/test_mem_fn.cpp:13: error:
call of overloaded 'mem_fn(ULONG (IDirect3DDevice9::*)())' is ambiguous
C:/Boost/include/boost-1_38/boost/bind/mem_fn_cc.hpp:15:
note: candidates are: boost::_mfi::mf0 boost::mem_fn(R (T::*)())
[with R = ULONG, T = IDirect3DDevice9]
C:/Boost/include/boost-1_38/boost/bind/mem_fn_cc.hpp:15:

Many thanks,
