https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D280579 Bug ID: 280579 Summary: devel/llvm11 devel/llvm12 devel/llvm13 devel/llvm14 devel/llvm15 devel/llvm16 devel/llvm17: fix build with libc++ 19 Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: brooks@FreeBSD.org Reporter: dim@FreeBSD.org Assignee: brooks@FreeBSD.org Flags: maintainer-feedback?(brooks@FreeBSD.org) devel/llvm17: fix build with libc++ 19 As noted in the libc++ 19 release notes [1], std::char_traits<> is now only provided for char, char8_t, char16_t, char32_t and wchar_t, and any instantiation for other types will fail. This causes devel/llvm17 to fail to compile with clang 19 and libc++ 19, resulting in errors similar to: /usr/include/c++/v1/string:820:42: error: implicit instantiation of undefined template 'std::char_traits<unsigned char>' 820 | static_assert(is_same<_CharT, typename traits_type::char_type>::value, | ^ =20=20=20 /wrkdirs/usr/ports/devel/llvm17/work-default/llvm-project-17.0.6.src/lldb/s= ource/Plugins/Process/gdb-remote/GDBRemoteCommunicationServerLLGS.cpp:634:3= 4: note: in instantiation of template class 'std::basic_string<unsigned char>' requested here 634 | std::basic_string<uint8_t> zeros(reg_info.byte_size, '\0'= ); | ^ /usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared he= re 23 | struct _LIBCPP_TEMPLATE_VIS char_traits; | ^ Upstream llvm has fixed this in commit 68744ffbdd7d [2], so add this as eit= her a PATCHFILES entry in the Makefile, or as a backported patch file.
