https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D281478 Bug ID: 281478 Summary: devel/libxsd-frontend: 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: kde@FreeBSD.org Reporter: dim@FreeBSD.org Flags: maintainer-feedback?(kde@FreeBSD.org) Assignee: kde@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 www/qt5-webengine 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<XSDFrontend::Bits::None>' 820 | static_assert(is_same<_CharT, typename traits_type::char_type>::value, | ^ =20 /wrkdirs/usr/ports/devel/libxsd-frontend/work/libxsd-frontend-2.1.0/libxsd-= frontend/xml.hxx:100:23: note: in instantiation of template class 'std::basic_string<XSDFrontend::Bits::None>' requested here 100 | NarrowString r (s); | ^ /usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared here 23 | struct _LIBCPP_TEMPLATE_VIS char_traits; | ^ The `Bits::None` construct used by libxsd-frontend is meant to disable unwanted conversions, but it no longer works if `std::char_traits>` is undefined for this type. Fix it by removing the `Bits` namespace and only enabling the converting constructors if the first type of `StringTemplate` is `wchar_t`.
