Error while using Boost Asio

Question

I get "::UnregisterWaitEx is not declared" inside win_object_handle_service.ipp whenever I try to include < boost/asio.hpp > into my code.

Currently I am using Code::Blocks, MinGW compiler (which didn't come bundled with IDE) on Windows 8.1.

Boost is built outside of mingw include folder, though is included in project settings.

Exact errors I am getting :

What I've tried:

1. Set _WIN32_WINNT to 0x0601 (Just one more warning added)
2. Added struct pollfd to winsock2.h as instructed in here (nothing happens)
3. Linked boost regex, system and thread libraries (or at least tried to)

Thanks in advance,

Nick

Answer 1

So, I fixed this error by adding "-D_WIN32_WINNT=0x0501 -DWINVER=0x0501" to both compilers linker options (in C::B) and #defines. Guess I added _WIN32_WINNT somehow wrong.
