i was running happily with boost 1.34.0 under Win32, using boost::program_options, boost_filesystem, and boost::thread. i decided to update to 1.35.0. I had to fix some broken code (e.g. boost::filesystem::filesystem_error does not have a member system_error() anymore) which was ok. Tell me if I am wrong, but now if i want to use a tiny boost::mutex (#include ), not only have I to define WIN32_LEAN_AND_MEAN before the include to avoid cryptic error messages due to the inclusion of winsock.h though i am using winsock2.h, but also I must now link to boost_thread AND to boost_system ? is this right ?

The new Boost.Thread uses Boost.DateTime for timeouts. Boost.DateTime includes , so you can either define WIN32_LEAN_AND_MEAN to avoid including , or you can include before any Boost.Thread headers. If you are only using boost::mutex, you do not need to link against the boost.thread library, though the auto-link stuff might try and force you to. On MSVC you can use the /nodefaultlib:library-name linker option to stop the linker complaining about a missing library, or you can just link against it anyway.
