Hello Boost-Community I have asked the following question everywhere
but nowhere has it been answered. I have now been advised to ask here.
I really hope there is someone on this mail list who can help me.
Unfortunately I don't have much time left and would be very grateful
for an answer.
With kind regards
Max
My Question:
I'm using normal Boost.NumPy functions in C++ like ndarray::get_data(),
and I get a "reference to unresolved external symbol" error. The .lib's
are linked and I have no approach on how to solve the error.
I am using Boost 1.74.
Here is a Code example:
#include
using namespace boost;
void func(python::object _obj)
{
python::numpy::ndarray my_ndarray =
python::extractboost::python::numpy::ndarray(_obj.attr("Member_01"));
char* data = my_ndarray.get_data();
}
BOOST_PYTHON_MODULE(ogwa_acc)
{
python::def("func", func);
}
Thats the one of the unresolved symbols: ""__declspec(dllimport)
public: char * __cdecl
boost::python::numpy::ndarray::get_data(void)const "
(_imp?get_data@ndarray@numpy@python@boost@@QEBAPEADXZ)"
I am using the normal Visual Studio linker and this is my linker
config:
