Hi Vicente, the commit 8853a4cbdf34d2699d7997ea99adf62fe9d6d568 broke compilation on windows: compile-c-c++ E: \dev\devel\boost\bin.v2\libs\thread\test\test_barrier_void_fct.test\msvc-12.0\debug\test_barrier_void_fct.obj test_barrier_void_fct.cpp E:\dev\devel\boost\boost/thread/win32/condition_variable.hpp(344) : error C2039: 'is_pos_infinity' : is not a member of 'boost::xtime' E:\dev\devel\boost\boost/thread/xtime.hpp(35) : see declaration of 'boost::xtime' E:\dev\devel\boost\boost/thread/win32/condition_variable.hpp(349) : error C2039: 'is_special' : is not a member of 'boost::xtime' E:\dev\devel\boost\boost/thread/xtime.hpp(35) : see declaration of 'boost::xtime' It seems you are calling Boost.DateTime special functions on boost::xtime variables. I'm not sure on how to fix this. The change has not been pickup by the regression matrix yet. Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold ! * voice: ++49 4257 300 !
