Hi,
I'm trying to compile the following code within MS Visual Studio IDE
.NET 2003. I compiled Boost 1.31.0 usign bjam, but I have the
requirement that all exposed into Python classes must be compiled within
IDE. "no_init" was specified because the original class has pure virtual
functions, but I get the same errors even without them. The original
class links and works fine on Linux/gcc, so I suppose I have problems
specific to VC7.1 and Windows.
class myclass
{
const char* name;
public:
myclass();
const char* getName();
};
myclass::myclass(): name("I'm a class")
{}
const char *myclass::getName()
{
return name;
}
using namespace boost::python;
BOOST_PYTHON_MODULE(testme)
{
class_<myclass,boost::noncopyable>("myclass", no_init)
.def("getName", &myclass::getName)
;
}
I specified libboost_python-vc71-mt-gd.lib as link library.
test_boost.obj : error LNK2019: unresolved external symbol
"__declspec(dllimport) void __cdecl
boost::python::objects::register_dynamic_id_aux(struct
boost::python::type_info,struct std::pair<void *,struct
boost::python::type_info> (__cdecl*)(void *))"
(__imp_?register_dynamic_id_aux at objects@python at boost@@YAXUtype_info at 23@P
6A?AU?$pair at PAXUtype_info@python at boost@@@std@@PAX at Z@Z) referenced in
function "void __cdecl boost::python::objects::register_dynamic_id<class
myclass>(class myclass *)"
(??$register_dynamic_id at Vmyclass@@@objects at python@boost@@YAXPAVmyclass@@

Am I missing something? Do I always need to write a wrapper class for
"no_init"?
Thanks,
Igor
