c++ - 如何在 Cygwin 64 位中使用 boost asio 库

Question

我正在运行 Windows 10 64 位。 Cygwin 是 64 位的。

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

但是编译失败。 看起来正在使用 posix。

知道为什么会失败吗？
