boost:asio ::UnregisterWaitEx has not been declare

问题:

I am trying to compile a basic client/server C++ program in eclipse with #include <boost/asio.hpp> using MinGW on Win7 and I get:

Description Resource    Path    Location    Type '::UnregisterWaitEx' has not been declared zion        line 106, external location: C:\boost_1_55_0\boost\asio\detail\impl\win_object_handle_service.ipp   C/C++ Problem

I included the path C:\boost_1_55_0 as well as the libraries boost_system and boost_asio.

Console output:

14:00:27 Build Finished (took 2s.579ms)

I tried looking in the .ipp but couldn't find anything very helpful. Something isn't declared but I am not sure what and nothing stands out in the boost.org documentation.

I haven't actually tried to implement any other boost code yet as it is not compiling even now but that might be what needs to be done?

The code I have now is a working client/server using winsock2 but I'd like to have it work on linux as well. Perhaps there is a conflict with the winsock2 code and boost::asio?

For eclipse, add symbol: _WIN32_WINNT val: 0x0601 (or for your windows system: http://msdn.microsoft.com/en-us/library/windows/desktop/aa383745%28v=vs.85%29.aspx) to resolve the primary issue.

The WSAPOLLFD issue is due to: https://github.com/mozilla/rust/issues/9246 && http://sourceforge.net/p/mingw/bugs/2049/ which is patched by adding:

typedef struct pollfd {
  SOCKET fd;
  short  events;
  short  revents;
} WSAPOLLFD, *PWSAPOLLFD, *LPWSAPOLLFD;

to winsock2.h.
