--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jonathan Wakely <[email protected]>: https://gcc.gnu.org/g:524bca2e33b56077b1ffe9e7526857afdbccce16 commit r16-4449-g524bca2e33b56077b1ffe9e7526857afdbccce16 Author: Jonathan Wakely <[email protected]> Date: Wed Oct 15 12:52:27 2025 +0100 libstdc++: Fix missing __to_timeout_timespec for targets using POSIX sleep [PR122293] The preprocessor condition for defining the new __to_timeout_timespec function templates did not match all the conditions under which it's needed. std::this_thread::sleep_for is defined #if ! defined _GLIBCXX_NO_SLEEP but it relies on __to_timeout_timespec which was only being defined for targets that use nanosleep, or clock_gettime, or use gthreads. For a non-gthreads target that uses POSIX sleep to implement std::this_thread::sleep_for, the build fails with: include/bits/this_thread_sleep.h:71:40: error: '__to_timeout_timespec' is not a member of 'std::chrono' [-Wtemplate-body] 71 | struct timespec __ts = chrono::__to_timeout_timespec(__rtime); | ^~~~~~~~~~~~~~~~~~~~~ Presumably the same would happen for mingw-w64 if configured with --disable-threads (as that would be a non-gthreads target that doesn't use nanosleep or clock_gettime). libstdc++-v3/ChangeLog: PR libstdc++/122293 * include/bits/chrono.h (__to_timeout_timespec): Fix preprocessor condition to match the conditions under which callers of this function are defined. * include/bits/this_thread_sleep.h: Remove unused include.
