https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D282386 Bug ID: 282386 Summary: emulators/dosbox-x: 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: eduardo@FreeBSD.org Reporter: dim@FreeBSD.org Assignee: eduardo@FreeBSD.org Flags: maintainer-feedback?(eduardo@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 emulators/dosbox-x 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 short>' 820 | static_assert(is_same<_CharT, typename traits_type::char_type>::value, | ^ dos_programs.cpp:7692:17: note: in instantiation of template class 'std::basic_string<unsigned short>' requested here 7692 | test_string dst; | ^ /usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared here 23 | struct _LIBCPP_TEMPLATE_VIS char_traits; | ^ dos_programs.cpp:8893:14: warning: variable 'open' set but not used [-Wunused-but-set-variable] 8893 | bool open=3Dfalse; | ^ This can be fixed by using char16_t for the 'test_char_t` type, and by adding a few inline wrappers to perform the required casting.
