I moved the is_monotonic static member var and the "now()" static member function to chrono.cc. I tried to model it after mutex and condition_variable but linking anything against libstdc++.so gives two linker error's. (Note that, on my x86_64 machine, the configuration does define _GLIBCXX_USE_GETTIMEOFDAY) libstdc++.so: undefined reference to 'std::common_type<std::chrono::duration<long, std::ratio<1l, 1l> >, std::chrono::duration<long, std::ratio<1l, 1000000l> > >::type std::chrono::operator+<long, std::ratio<1l, 1l>, long, std::ratio<1l, 1000000l> >(std::chrono::duration<long, std::ratio<1l, 1l> > const&, std::chrono::duration<long, std::ratio<1l, 1000000l> > const&)' libstdc++.so: undefined reference to 'std::common_type<std::chrono::duration<long, std::ratio<1l, 1000000l> >, std::chrono::duration<long, std::ratio<1l, 1000000l> > >::type std::chrono::operator+<long, std::ratio<1l, 1000000l>, long, std::ratio<1l, 1000000l> >(std::chrono::duration<long, std::ratio<1l, 1000000l> > const&, std::chrono::duration<long, std::ratio<1l, 1000000l> > const&)' Sorry for the formatting but basically it can't find operator+ for durations (the first is the seconds + microseconds). Both additions are valid so I figure I haven't integrated chrono.cc correctly into the build system or I'm just doing something silly... Chris
