<div>Hello.</div>
<div> </div>
<div>I need to compile Boost for Windows CE. This is unfortunate, since there are two things I know nearly nothing about: Boost.Build, and Windows development. The release notes of 1.47 indicate that it has been successfully compiled for Windows CE using STLport, but that was using Boost.Build and for reasons I won&#39;t go into here (wrong mailing list), it didn&#39;t work for me. Thankfully, my problems with Boost.Build can be helped by the existence of the CMake project for Boost (thanks!). Since I don&#39;t know much about Windows, I thought I&#39;d try and use CEgcc on Linux.</div>

<div> </div>
<div>I feel like I&#39;m making good progress, but I eventually hit this error:</div>
<div> </div>
<div>boost/config/requires_threads.hpp:47:5: error: #error &quot;Compiler threading support is not turned on. Please set the correct command line options for threading: -pthread (Linux), -pthreads (Solaris) or -mthreads (Mingw32)&quot; </div>

<div> </div>
<div>-mthreads is part of the C and CXX flags-- the problem is that BOOST_PLATFORM_CONFIG is not defined by boost/config/select_platform_config.hpp. What should this be defined to for Windows CE? I figured it should be boost/config/platform/win32.hpp (which would then define BOOST_HAS_WINTHREADS, which would solve the above error). How can the release notes claim this works when select_platform_config.hpp doesn&#39;t seem to handle Windows CE cases? If BOOST_PLATFORM_CONFIG does indeed need to be boost/config/platform/win32.hpp, then I need to define either _WIN32, __WIN32__, or WIN32. My first reaction is that none of these should be used for compiling for CE. I would welcome any ideas!</div>

<div> </div>
<div>Note that I would also welcome suggestions on how to compile for Windows CE using STLport with CMake on Windows. Thank you!</div>
