https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D255374 --- Comment #32 from Mark Millard <marklmi26-fbsd@yahoo.com> --- I will note that for LLVM16 there will still be in /usr/include/c++/v1/__config the likes of (from openSUSE tumbleweed libc++ installation): . . . #ifdef __cplusplus // _LIBCPP_VERSION represents the version of libc++, which matches the vers= ion of LLVM. // Given a LLVM release LLVM XX.YY.ZZ (e.g. LLVM 16.0.1 =3D=3D 16.00.01), _LIBCPP_VERSION is // defined to XXYYZZ. # define _LIBCPP_VERSION 160002 . . . # if __has_feature(experimental_library) # ifndef _LIBCPP_ENABLE_EXPERIMENTAL # define _LIBCPP_ENABLE_EXPERIMENTAL # endif # endif // Incomplete features get their own specific disabling flags. This makes it // easier to grep for target specific flags once the feature is complete. # if !defined(_LIBCPP_ENABLE_EXPERIMENTAL) && !defined(_LIBCPP_BUILDING_LIBRARY) # define _LIBCPP_HAS_NO_INCOMPLETE_FORMAT # endif . . . which will make -fexperimental-library required in order to have C++20's std::format generally enabled: still considered experimental in LLVM16. --=20 You are receiving this mail because: You are on the CC list for the bug.=
