python - 从 anaconda 将 Python 嵌入到 C++ 中，出现错误

Question

试图编译这个a.cpp文件，使用

g++ a.cpp -I ~/anaconda3/include/python3.7m/ -l ~/anaconda3/lib/python3.7/

我得到的错误是

/usr/bin/ld: cannot find -l/home/rverma/anaconda3/lib/python3.7/
collect2: error: ld returned 1 exit status

也试过g++ a.cpp -I ~/anaconda3/include/python3.7m/ -l ~/anaconda3/lib/这个

/usr/bin/ld: cannot find -l/home/rverma/anaconda3/lib/ collect2: error: ld returned 1 exit status

我的a.cpp文件如下所示：

#include <Python.h>
#include <stdlib.h>
int main()
{
   // Set PYTHONPATH TO working directory
   setenv("PYTHONPATH",".",1);

   PyObject *pName, *pModule, *pDict, *pFunc, *pValue, *presult;


   // Initialize the Python Interpreter
   Py_Initialize();


   // Build the name object
   pName = PyUnicode_FromString((char*)"arbName");

   // Load the module object
   pModule = PyImport_Import(pName);


   // pDict is a borrowed reference 
   pDict = PyModule_GetDict(pModule);


   // pFunc is also a borrowed reference 
   pFunc = PyDict_GetItemString(pDict, (char*)"someFunction");

   if (PyCallable_Check(pFunc))
   {
       pValue=Py_BuildValue("(z)",(char*)"something");
       PyErr_Print();
       printf("Let's give this a shot!\n");
       presult=PyObject_CallObject(pFunc,pValue);
       PyErr_Print();
   } else 
   {
       PyErr_Print();
   }
   printf("Result is %ld\n",PyLong_AsLong(presult));
   Py_DECREF(pValue);

   // Clean up
   Py_DECREF(pModule);
   Py_DECREF(pName);

   // Finish the Python Interpreter
   Py_Finalize();


    return 0;
}

我的argName.py样子是这样的：

def someFunction(text):
    print 'You passed this Python program '+text+' from C! Congratulations!'
    return 12345

请帮忙
