Manuel Pöter updated IGNITE-24990:
----------------------------------
Description:
After a recent XCode update MacOS C++ builds are broken with the following
error:
{code:java}
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/string_view:300:42:

make[2]: *** [utils/CMakeFiles/utils.dir/file_checked.cpp.o] Error 1
make[1]: *** [utils/CMakeFiles/utils.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs.... {code}
The reason is the following deprecation (see [release
notes]([https://developer.apple.com/documentation/xcode-release-notes/xcode-16_3-release-notes)):]
{quote}The base template for std::char_traits has been removed. If you are
using std::char_traits with types other than char, wchar_t, char8_t, char16_t,
char32_t or a custom character type for which you specialized std::char_traits,
your code will stop working. The Standard does not mandate that a base template
is provided, and such a base template is bound to be incorrect for some types,
which could previously cause unexpected behavior while going undetected.
