Comment (by cjones051073):

 Just curious. *why* are you trying to install using gcc12 ? Using gcc to
 build c++ sources is problematic on macOS, due to the potential for mixing
 incompatible c++ runtimes (libstdc++ versus libc++). Genrially speaking
 its better to just stick to the defaults, which in this case work.
