Dear all, I've just upgraded the boost library from 1.34 to 1.37 on Windows. When I try to compile our software with the new library version (both with VS 7.0 and with VS 9.0) I meet 2 different kind of problems. In our software we instantiate the class boost::recursive_mutex::scoped_lock (instance of the template unique_lock), and one problem seems that the class boost::recursive_mutex doesn't implement the function unlock_upgrade_and_lock. I'm compiling the code settings the define BOOST_THREAD_WIN32, I don't know if there are others defines to be specified. Follow the VS 9.0 output (with the compilation errors): ... 1>d:\masterfinancedevl\admindevl\devl\ext70\inc\boost7.1\boost\thread\locks.hpp(406) : warning C4661: 'boost::unique_lock<Mutex>

Have you any suggestion on how to solve our compilation problem? thanks in advance best regards Matteo -- View this message in context: http://www.nabble.com/Compilation-errors-upgrading-boost-from-1.34-to-1.37-%...
