Asio not working on windows due to QueueUserAPC missing in global namespace

[Stephan Menzel <stephan.menzel@…>]

Hi Chris,

I just thought I open a ticket here for better handling: The problem has been described by someone else, but I have it too. It's quite simple, although perhaps not the solution. ​http://groups.google.tl/group/boost-list/browse_thread/thread/c19823879d3cdecc

Basically, Asio in 1.37 is not compiling on windows. I get the following error: 'QueueUserAPC' : is not a member of 'operatorglobal namespace

Greetings and Thanks...

Stephan

This is due to _WIN32_WINNT not being defined when Windows.h is first included and/or the value of the #define being changed before asio.hpp is included. To work correctly, _WIN32_WINNT should be defined on the compiler command line or in the project options.

(In [50945]) Improve warning message when _WIN32_WINNT is not correctly defined. Fixes #2541.

Hi Chris,

I'm not sure it's that easy. _WIN32_WINNT is set here in the project options (MSVC2005) and never changes it's value within my project as far as I can see.

Here's the cmdline options:

/Od /I <several includes> /D "WIN32" /D "_WINDOWS" /D "_DEBUG" /D "WIN32_LEAN_AND_MEAN" /D "_WIN32_WINNT" /D "_CRT_SECURE_NO_WARNINGS" /D "BOOST_ALL_DYN_LINK" /D "CMAKE_INTDIR=\"Debug\"" /D "_WINDLL" /D "_MBCS" /FD /EHsc /RTC1 /MDd /Fo"commons.dir\Debug
" /W3 /nologo /c /Zi /TP /errorReport:prompt

Thanks for caring though!

HTH,

Stephan

You need to make sure you define _WIN32_WINNT to a particular value indicating the target platform. E.g. try changing command line so it has:

/D "_WIN32_WINNT=0x501"

I have enhanced the warning message emitted by asio to make this clearer (see changeset [50945]).

OMG, should've known.

Works, thank you very much and sorry for the trouble. To hell with windows and all those defines.

Cazart,

Stephan
