I try to update port of WebKitGtk on FreeBSD, and since the 2.40.0 release, each build fails (no problem with the 2.38.x releases). It is always in same stage. It is not easy to find root cause, because sources are huge. >FAILED: Source/WebKit/CMakeFiles/WebKit.dir/__/__/DerivedSources/WebKit/unified-sources/UnifiedSource-54928a2b-22.cpp.o > >In file included from <built-in>:1: >In file included from /usr/ports/www/webkit2-gtk4/work/webkitgtk-2.40.2/Source/WebKit/WebKit2Prefix.h:75: >In file included from /usr/include/c++/v1/algorithm:667: >In file included from /usr/include/c++/v1/functional:499: >In file included from /usr/include/c++/v1/__functional/bind.h:17: >/usr/include/c++/v1/tuple:1596:5: error: attempt to use a deleted function > _VSTD::__invoke_constexpr( > ^ >/usr/include/c++/v1/__config:826:15: note: expanded from macro '_VSTD' >#define _VSTD std > ^ Full log is available here [1] (and with clang 15 [2]). Tested with clang 14 (this is default compiler) and clang 15. Previous maintainer activated c++20 features (but I also tested with -std=gnu++20, because with gcc this stage finished well, and -std=c++11). When unified sources are disabled (-DENABLE_UNIFIED_BUILDS=OFF), compilation fails much earlier. Below options used: -- ENABLE_BUBBLEWRAP_SANDBOX .....................
