So, just for the record, there is currently no support for building boost for Windos 8/Store/Metro Apps (using the WinRT API), and the plans to support it are far from concrete. Sadly I cannot offer to work on the patches, since the we decided to remove the boost dependencies from our codebase. But for the ones willing to dive in, this is a good starting point: http://msdn.microsoft.com/en-us/library/windows/apps/br205762.aspx http://msdn.microsoft.com/en-us/library/windows/apps/br211377.aspx As Vicente said, the main things that are broken are Boost.Thread and Boost.Chrono, but Boost.Filesystem also needs a good look. And if you want to jump right into the code, build boost with the following commandline params: .\b2 cxxflags="-DWINAPI_FAMILY=WINAPI_FAMILY_APP -D_WIN32_WINNT=0x0602" linkflags="/APPCONTAINER" Ceers Johannes
