Description
While compiling on macOS I've seen the following warnings:
[2/3] Building CXX object tests/auto/corelib/text/qbytearrayview/CMakeFiles/tst_qbytearrayview.dir/tst_qbytearrayview.cpp.o /Users/cristian/Projects/Qt/repo/qtbase/tests/auto/corelib/text/qbytearrayview/tst_qbytearrayview.cpp:522:39: warning: 'char_traits<unsigned char>' is deprecated: char_traits<T> for T not equal to char, wchar_t, char8_t, char16_t or char32_t is non-standard and is provided for a temporary period. It will be removed in LLVM 18, so please migrate off of it. [-Wdeprecated-declarations] size_t size(const T *t) { return std::char_traits<T>::length(t); }
I have noticed this while trying to build the test for Cosmopolitan Libc, where it fails to compile.
The Clang/libc++ developers were serious about this warning and they've removed support for it at https://reviews.llvm.org/D157058
Other projects were affected by this https://github.com/jtv/libpqxx/issues/738 and https://github.com/doxygen/doxygen/issues/10928
The test needs to be updated not to use std::char_traits<std::byte>. This should be visible when trying to compile with LLVM/Clang 19!
