             Bug #: 54847

           Summary: --enable-libstdcxx-time=yes non-functional on darwin

    Classification: Unclassified

           Product: gcc

           Version: 4.8.0

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: libstdc++

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: howa...@nitro.med.uc.edu





The configure option --enable-libstdcxx-time=yes is non-functional on darwin

because the associated configure test requires posix-timer support which darwin

lacks. Darwin also lacks support for the tested clock_gettime call but does

have the sched_yield call available. Also it is odd that

--enable-libstdcxx-timer has been defaulted to no as this has left many darwin

users (including MacPorts) assuming that they are enabling it with that option.
