[英]Embed python code in C++ (Windows + minGW + Python 2.7.2 + Eclipse)
我正在尝试在C++ (Windows 7 + minGW + Python 2.7.2 + Eclipse Indigo with CDT and PyDev)
嵌入python代码C++ (Windows 7 + minGW + Python 2.7.2 + Eclipse Indigo with CDT and PyDev)
。
所以,这是简单的代码:
#include <Python.h> //Python.h
#include <iostream> //iostream
using namespace std;
int main(int argc, char *argv[])
{
Py_Initialize();
PyRun_SimpleString("from time import time,ctime\n"
"print('Today is', ctime(time()))\n");
Py_Finalize();
return 0;
}
我无法理解我做错了什么。 我包括dirrctories C:\\Python27\\include
和C:\\Python27\\lib
s但我无法构建我的项目。
1)当我尝试构建我的项目时,我收到此错误:
**** Internal Builder is used for build **** g++
-IC:\Python27\include -IC:\Python27\libs -O0 -g3 -Wall -c
-fmessage-length=0 -o main.o ..\main.cpp g++ -o testpy2.exe main.o

collect2: ld returned 1 exit status
Build error occurred, build is stopped Time consumed: 1507 ms.
2)如果我将Eclipse中的当前工具链从“minGW”更改为“CrossGCC”..我收到此错误:
**** Build of configuration Release for project testpy ****

exit status make: *** [testpy.exe] Error 1

有人能告诉我我的代码或设置有什么问题吗?
谢谢
这是链接器错误,而不是编译器错误。 你需要链接到python。 正如您所看到的,使用“CrossGCC”工具链,您几乎就在那里:
-lC:/Python27/libs/libpython27.a
您需要将其更改为
-LC:/Python27/libs -lpython
