C++ headers missing in /usr/include/c++/v1/ (ignoring C++23 in-progress material) for: # uname -apKU FreeBSD CA72_16Gp_ZFS 14.0-CURRENT FreeBSD 14.0-CURRENT #25 main-n251456-22c4ab6cb015-dirty: Tue Dec 7 19:38:53 PST 2021 root@CA72_16Gp_ZFS:/usr/obj/BUILDs/main-CA72-nodbg-clang/usr/main-src/arm64.aarch64/sys/GENERIC-NODBG-CA72 arm64 aarch64 1400043 1400043 starting with C++ specific headers: coroutine (C++20) source_location (C++20) memory_resource (C++17) cuchar (C++11) syncstream (C++20) stop_token (C++20) C compatibility headers (which C++23 looks to give the status: undeprecated) ( not analyzed for if covered via outside /usr/include/c++/v1/ ) assert.h signal.h stdarg.h time.h uchar.h Others (empty/meaningless yet part of the standard): ctgmath.h (actually: C++20 removed this one) cstdalign (actually: C++20 removed this one) iso646.h stdalign.h I ignore experimental/* status files. I have not checked if any of these are missing from libc++ in a way not specific to FreeBSD: I just compared material about the standard versions to the file names in /usr/include/c++/v1/ . === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
