Question

我遇到了最新的cygwin g ++ - 5.4.0和python3.4这个问题。以下简单的代码暴露了这个问题：

#include <string>
#include <Python.h>
#include <vector>
#include <map>
//#include <string>
#include <iostream>

int main(int argc, char ** argv)
{
    return 0;
}

用＆＃34;编译后g ++ -g -O2 -std = c ++ 11 test.c -o test python3-config --includes＆＃34;，我收到了以下错误：

In file included from /usr/include/python3.4m/Python.h:8:0,
                 from test.c:2:

一个棘手的问题是，如果我包含＆＃34; Python.h＆＃34;。编译通过。我在linux / Mac OS上没有看到这个问题。

我不认为这是一个有效的解决方案。由于代码更复杂，我在程序的最开始（在进入main函数之前）遇到段默认值。

修改文件/usr/include/python3.4m/pyconfig.h，替换

#define __BSD_VISIBLE 1

与

#define __BSD_VISIBLE 0

cygwin g ++使用Python.h进行编译（__BSD_VISIBLE的重复定义）
