Hi all, I'm trying out boost.python to use c++ code in python. My problem is this: In my c++ code, if i declare the class constructor in the header file, and define it in the cpp file, bjam throws a LNK2019 unresolved symbol error. The problem does not occur if i define the constructor in the header file itself. My code is shown below: *Test1.h:* #include //using namespace std; class World { public: World(); ~World(); void set(std::string msg) { this->msg = msg; } std::string greet() { return msg; } std::string msg; }; *Test1.cpp:* #include "Test1.h" World::World() {}; World::~World() {}; int addition(int a, int b) { int z = a + b; return z; } *Wrapper File*: #include #include "Test1.h" BOOST_PYTHON_MODULE(hello) { using namespace boost::python; class_<World>("World") .def("greet", &World::greet) .def("set", &World::set) ; } Is this a bug? Or there's something wrong with my coding here? -- Regards, Hitesh Dhiman Electrical Engineering National University of Singapore
