Ok, probably Catalina/Big Sur problem (>=darwin19)
see also https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248726
(In reply to Fabian Groffen from comment #4) > see also > https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248726 Didn't help, I guess it's to do with the BSD/Clang libstdc++ stuff. Interestingly, the death occurs in gcc's chrono.h - which relies on _GLIBCXX_HAVE_TIMESPEC_GET which is set to 1. Unsetting this in c++config.h 'fixes' the problem but I've got no idea why GCC believed that to be true. I guess I need to figure out how g++config.h is setup when building gcc.
Well, GLIBC isn't a thing on macOS of course, so someone is defining things that shouldn't be. Probably, that was the BSD workaround doing: ensuring this thing wouldn't get defined.
(In reply to Fabian Groffen from comment #6) > Well, GLIBC isn't a thing on macOS of course, so someone is defining things > that shouldn't be. Probably, that was the BSD workaround doing: ensuring > this thing wouldn't get defined. I think it's worse than that - GLIBCXX is the standard name gcc use internally for their headers, unrelated to glibc, see https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_macros.html. I had a dig around and configure is picking it up when building libstdc++, but I didn't fully get why. I then came across this: https://reviews.llvm.org/rG99f3b231cb21abc567c93813650cd76cfa614325 https://bugs.llvm.org/show_bug.cgi?id=47208 So... we force GCC not to detect it (because it isn't always available) via forcing ac_cv_func_timespec_get=no, or add a guard in libstdc++-v3/config.h.inc (or libstdc++-v3/include/c_global/ctime really)? It seems to me like this is a GCC bug in its libstdc++ implementation which was already fixed in Clang, but I don't want to rush into reporting it upstream if I'm barking up the wrong tree.
timespec_get is available, but not in c++ mode: [febe:~] fabian% gcc -o x x.c [febe:~] fabian% g++ -o x x.c x.c: In function ‘int main()’: x.c:7:20: error: ‘TIME_UTC’ was not declared in this scope 7 | timespec_get(&ts, TIME_UTC); | ^~~~~~~~ x.c:7:2: error: ‘timespec_get’ was not declared in this scope; did you mean ‘timespec’? 7 | timespec_get(&ts, TIME_UTC); | ^~~~~~~~~~~~ | timespec [febe:~] fabian% this is probably due that happens in the time.h header: #if (__DARWIN_C_LEVEL >= __DARWIN_C_FULL) && \ ((defined(__STDC_VERSION__) && __STDC_VERSION__ >= 201112L) || \ (defined(__cplusplus) && __cplusplus >= 201703L)) /* ISO/IEC 9899:201x 7.27.2.5 The timespec_get function */ #define TIME_UTC 1 /* time elapsed since epoch */ __API_AVAILABLE(macosx(10.15), ios(13.0), tvos(13.0), watchos(6.0)) int timespec_get(struct timespec *ts, int base); #endif By default for me, __DARWIN_C_LEVEL == __DARWIN_C_FULL and __STDC_VERSION__ is unset, while __cplusplus == 201402. E.g. the function is not made available.
(so we need g++ -std=c++17 -o x x.c)
(In reply to Fabian Groffen from comment #9) > (so we need g++ -std=c++17 -o x x.c) That was in CMake’s invocation though, right?
this has a similar odour: https://gitlab.kitware.com/cmake/cmake/-/issues/21135
It's proven once again that messing around with POSIX standards on a UNIX system breaks stuff. Modifying cmLoadCommandCommand.cxx cmStandardLexer.h cmSystemTools.cxx cmTimestamp.cxx in a way like: -#if !defined(_WIN32) && !defined(__sun) +#if !defined(_WIN32) && !defined(__sun) && !defined(__APPLE__) make cmake compile without any itch here.
