--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-8 branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:655434f5ae93a4222a48c39c37a3a6fe0bdfc071 commit r8-10089-g655434f5ae93a4222a48c39c37a3a6fe0bdfc071 Author: Jonathan Wakely <jwak...@redhat.com> Date: Wed Feb 26 15:32:34 2020 +0000 libstdc++: Replace glibc-specific check for clock_gettime (PR 93325) It's wrong to assume that clock_gettime is unavailable on any *-*-linux* target that doesn't have glibc 2.17 or later. Use a generic test instead of using __GLIBC_PREREQ. Only do that test when is_hosted=yes so that we don't get an error for cross targets without a working linker. This ensures that C library's clock_gettime will be used on non-glibc targets, instead of an incorrect syscall to SYS_clock_gettime. Backport from mainline 2020-01-28 Jonathan Wakely <jwak...@redhat.com> PR libstdc++/93325 * acinclude.m4 (GLIBCXX_ENABLE_LIBSTDCXX_TIME): Use AC_SEARCH_LIBS for clock_gettime instead of explicit glibc version check. * configure: Regenerate.
