The branch 2024Q4 has been updated by cmt: URL: https://cgit.FreeBSD.org/ports/commit/?id=c5b74ac54ae1c5510a2fda3d3d7211e73c7745ae commit c5b74ac54ae1c5510a2fda3d3d7211e73c7745ae Author: Dimitry Andric <dim@FreeBSD.org> AuthorDate: 2024-10-07 20:50:06 +0000 Commit: Christoph Moench-Tegeder <cmt@FreeBSD.org> CommitDate: 2024-10-07 20:54:46 +0000 cad/kicad: 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 cad/kicad to fail to compile with clang 19 and libc++ 19, resulting in errors similar to: /wrkdirs/usr/ports/cad/kicad/work/kicad-7.0.2/thirdparty/nanodbc/nanodbc/nanodbc.cpp:261:25: error: implicit instantiation of undefined template 'std::char_traits<unsigned short>' 261 | auto const n = std::char_traits<NANODBC_SQLCHAR>::length(array); | ^ /usr/include/c++/v1/__string/char_traits.h:45:8: note: template is declared here 45 | struct char_traits; | ^ /wrkdirs/usr/ports/cad/kicad/work/kicad-7.0.2/thirdparty/nanodbc/nanodbc/nanodbc.cpp:3576:52: error: implicit instantiation of undefined template 'std::char_traits<unsigned short>' 3576 | dsn.name = string(&name[0], &name[std::char_traits<NANODBC_SQLCHAR>::length(name)]); | ^ /usr/include/c++/v1/__string/char_traits.h:45:8: note: template is declared here 45 | struct char_traits; | ^ /wrkdirs/usr/ports/cad/kicad/work/kicad-7.0.2/thirdparty/nanodbc/nanodbc/nanodbc.cpp:3578:49: error: implicit instantiation of undefined template 'std::char_traits<unsigned short>' 3578 | string(&driver[0], &driver[std::char_traits<NANODBC_SQLCHAR>::length(driver)]); | ^ /usr/include/c++/v1/__string/char_traits.h:45:8: note: template is declared here 45 | struct char_traits; | ^ /wrkdirs/usr/ports/cad/kicad/work/kicad-7.0.2/thirdparty/nanodbc/nanodbc/nanodbc.cpp:3629:54: error: implicit instantiation of undefined template 'std::char_traits<unsigned short>' 3629 | drv.name = string(&descr[0], &descr[std::char_traits<NANODBC_SQLCHAR>::length(descr)]); | ^ /usr/include/c++/v1/__string/char_traits.h:45:8: note: template is declared here 45 | struct char_traits; | ^ and: /usr/include/c++/v1/string:820:42: error: implicit instantiation of undefined template 'std::char_traits<unsigned short>' 820 | static_assert(is_same<_CharT, typename traits_type::char_type>::value, | ^ /wrkdirs/usr/ports/cad/kicad/work/kicad-7.0.2/thirdparty/compoundfilereader/compoundfilereader.h:226:21: note: in instantiation of template class 'std::basic_string<unsigned short>' requested here 226 | utf16string dir; | ^ /usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared here 23 | struct _LIBCPP_TEMPLATE_VIS char_traits; | ^ The first batch of errors can be fixed by providing a simple `length()` function for the `NANODBC_SQLCHAR const*` type.
