https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D282524 Bug ID: 282524 Summary: science/py-dlib: 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: arrowd@FreeBSD.org Reporter: dim@FreeBSD.org Flags: maintainer-feedback?(arrowd@FreeBSD.org) Assignee: arrowd@FreeBSD.org 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 science/py-dlib 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 undef= ined template 'std::char_traits<unsigned int>' 820 | static_assert(is_same<_CharT, typename traits_type::char_type>::value, | ^ =20 /wrkdirs/usr/ports/science/py-dlib/work-py311/dlib-19.24.6/dlib/bigint/../u= nicode/unicode.h:718:19: note: in instantiation of template class 'std::basic_string<unsigned int>' requested here 718 | const ustring convert_to_utf32 ( | ^ /usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared here 23 | struct _LIBCPP_TEMPLATE_VIS char_traits; | ^ This can be fixed by defining `unichar` as `char32_t` instead of `uint32` in `unicode.h`, and adding a serializer for `char32_t` to `serialize.h`.
