Embedding Python: undefined reference to `_imp__Py_Initialize'

Question

I am trying to embed python 3.7.0 in a C++ application and use MinGW to compile.

#include "Dependencies/include/Python.h"


int main()
{

    PyObject* myPointer;
    Py_Initialize();
    return 0;
}

I compile with this:

g++ ./TestEmbedding.cpp

I get this error:

undefined reference to `_imp__Py_Initialize'

EDIT: Found and Answer:

The path to the python libs file needs to be included. I personally am now using Visual Studio and just included it in the settings but I think MinGW can do it with some command line adjustments.

include something similar to this in library paths. C:Local\Programs\Python\Python37\Lib

You need to build with Python headers:

g++ TestEmbedding.cpp `python3-config --includes` -o TestEmbedding
