將Python程序嵌入到GTK應用程序中（用C語言編寫）

Question

我正在編寫GTK + GUI（C語言）應用程序，我之前已經快速開發了執行某些任務的pygtk GUI應用程序。 現在，我希望不再只是用C和GTK +重寫整個Pygtk GUI及其計算例程，而是希望僅按C GUI中的一個按鈕並取消python GUI。

最初嘗試使用C代碼調用python GUI，但在運行時崩潰，它抱怨GTK導入和分段錯誤。

請注意，Python GUI獨立應用程序可以正常運行（獨立文件的名稱為FPG.py）。

那么如何有效地將模塊和庫從python導入C / C ++

這是我所做的：

#include <Python.h>

int
main(int argc, char *argv[])
{
 Py_SetProgramName(argv[0]);  /* optional but recommended */
 Py_Initialize();

 FILE *fp      = fopen ("FPG.py",   "r+");
 PyRun_SimpleString("#!/usr/bin/python2.7");
 PyRun_SimpleString("import sys ");
 PyRun_SimpleString("from scipy.integrate import odeint ");
 PyRun_SimpleString("import math ");
 PyRun_SimpleString("import csv ");
 PyRun_SimpleString("from decimal import *");
 PyRun_SimpleString("from math import pi ");
 PyRun_SimpleString("import numpy as np");
 PyRun_SimpleString("from datetime import datetime");
 PyRun_SimpleString("from time import mktime ");
 PyRun_SimpleString("from gi.repository import Gtk, Gio");
 PyRun_SimpleString("import os");


 PyRun_SimpleString("from datetime import datetime");
 PyRun_SimpleString("from time import mktime");

 // the actual file  
 PyRun_SimpleFile(fp,"FPG.py");
 Py_Finalize();
 return 0;
}

我按如下方式編譯了程序（我知道它是C ++編譯器）：

g++ $(python-config --cflags) -o simple $(python-config --ldflags) ./simple.cpp

該程序即使編譯，在運行時也會由於輸出可執行文件的以下摘錄而崩潰。

您輸入了mport numpy as np錯過了i 。 另外，您必須為argv導入sys模塊。
