Question

我正在运行Windows 10 64位。 Cygwin是64位。

我从cygwin包管理器安装了boost。

我尝试编译test.cpp：

#include <boost/asio.hpp>
int
main(int argc, char**argv)
{
    return 0;
}

使用命令

g++ -std=c++11 -Wall -g  -D__USE_W32_SOCKETS D_WIN32_WINNT=_WIN32_WINNT_WIN7 test.cpp -o test.exe

但编译失败。 看起来正在使用posix 。

为什么会失败的任何想法？

感谢#cygwin IRC的帮助：

g++ -std=c++11 -Wall -g -D_XOPEN_SOURCE=500 test.cpp -o test.exe -lboost_system
