[C++-sig] Boost Python & __declspec(dllimport) int __stdcall

[Jon Clements]

Hi All,

I've had a look for something regarding the above but couldn't find anything, so apologies if I'm digging up what's been buried.

I have a 3rd party header file which contains the declarations for a DLL. One of the lines is:-
    __declspec(dllimport) int __stdcall System_Startup(long);

I have the following attempting to wrap it: -

BOOST_PYTHON_MODULE(xxx)
{
def("startup",&System_Startup)
}

When compiling with VC++ 8 Express Edition, I get:-

1>C:\boost\boost_1_33_1\boost/python/make_function.hpp(104) : error C2780: 'boost::mpl::vector17<RT,most_derived<Target,ClassT>::type&,T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14> boost::python::detail::get_signature(RT (__thiscall ClassT::* )(T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14) volatile const,Target *)' : expects 2 arguments - 1 provided

I'm somewhat flummoxed as to where to even start looking - any tips?

Thanks in advance,

Jon.
