cygwin g ++用Python.h编译（__BSD_VISIBLE的重复定义）

我遇到了这个问题，最新的cygwin g ++ - 5.4.0和python3.4。下面简单的代码公开此问题：cygwin g ++用Python.h编译（__BSD_VISIBLE的重复定义）

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

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

与编译后的 “g ++ -g -02 -std = C++ 11 test.c的-o测试python3-config --includes”，我得到了以下错误：

In file included from /usr/include/python3.4m/Python.h:8:0, 
       from test.c:2: 
/usr/include/python3.4m/pyconfig.h:1440:0: warning: "__BSD_VISIBLE" redefined 
#define __BSD_VISIBLE 1 
^

/usr/include/sys/time.h:104:34: error: 'u_int' has not been declared bintime_mul(struct bintime *_bt, u_int _x)

一个棘手的问题是，如果我在“Python.h”之后加入。编译通过。我在linux/Mac OS上看不到这个问题。

我不认为这是一个有效的解决方案。由于使用更复杂的代码，我在程序的最开始处（在进入主函数之前）遇到了段默认值。

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

#define __BSD_VISIBLE 0

更换

#define __BSD_VISIBLE 1
