Ubuntu 16.04下C++调用Python3.5程序

Ubuntu 16.04下C++调用Python3.5程序

在Ubuntu 16.04下C++调用Python3.5程序过程记录。

Python程序

#call.py
import sys
def call():
    print("hello world")
if __name__ = '__main__':
    call()

C++代码

#include <iostream>
#include <boost/python.hpp>
using namespace std;
using namespace boost::python;
int main()
{
 Py_Initialize();
 if (!Py_IsInitialize())
 {
  cout << 'Fail 1' << endl;
  return -1;
 }
 Pyrun_SimpleString("import sys")
 int argc = 1;
 wchar_t argv[1]; //python2使用char,与python3有区别
 argv[0] = L"/home/tyl/code/call.py";
 PySys_setArgv(argc,argv);
 if (PyRun_SimpleString("exec(open('/home/tyl/code/call.py').read())"))
 {
  cout << "Fail 2" <<endl;
  return -1;
 }
 Py_Finalize();
 return 0;
}
