- Just check if
-Werror=format-securityhas been enabled in theCFLAGSof your/etc/makepkg.conf. If you don't want to edit/etc/makepkg.conf, just add the line
CFLAGS=${CFLAGS/-Werror=format-security/}
below the already existing CFLAGS definition in the build() section of PKGBUILD, and
CXXFLAGS=${CXXFLAGS/-Werror=format-security/}
after the CXXFLAGS definition.

In addition to the jamespharvey20's sticky comment: The current GCC 12 versions are labelled "Experimental" for a reason. Development is ongoing, and there are still significant bugs. Hence, it is not recommended to use GCC 12 as a daily driver or on production systems.
At the moment, it is not even possible to build a working Linux kernel with GCC 12, see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101941 .
