hi.
i have used boost python to create the sample from the doc within visual
studio. a dll has resulted. but when i copy that dll to any of numerous
places on my path, and run a python shell, i keep getting:
ImportError: no module named hello
Here is the code, it's contained in 2 modules within visual c++ (maybe that
part of the problem?):
***** first module *****
// boost_pyth_01.cpp : Defines the exported functions for the DLL
application.
//
#include <boost/python.hpp>
using namespace boost::python;
//#include "stdafx.h"
__declspec(dllexport) struct World
{
void set(std::string msg) { this->msg = msg; }
std::string greet() { return msg; }
std::string msg;
};
BOOST_PYTHON_MODULE(hello)
{
class_<World>("World")
.def("greet", &World::greet)
.def("set", &World::set)
;
}
***** and, second module *****
// dllmain.cpp : Defines the entry point for the DLL application.
#include "stdafx.h"
BOOL APIENTRY DllMain( HMODULE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}
it does build a dll, named after my project name in the first module. i
copied this dll to numerous places on my path. still get the error above in
the python shell.
also i get this warning during the link:
1>d:\cpp_testing\boost_pyth_01\boost_pyth_01.cpp(15) : warning C4091:
'__declspec(dllexport)' : ignored on left of 'World' when no variable is
declared
