Iain Sandoe <iains at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Target Milestone|--- |13.0 --- Comment #9 from Iain Sandoe <iains at gcc dot gnu.org> --- (I don't have a macOS13 setup yet, limited hardware available here) ... so, if it is not fixed in the Xcode 14.x releases, we'll have to work around it in the GCC sources. Work-around is to add this to the 'make' command line. BOOT_CFLAGS="-O2 -g -Wno-error=deprecated-declarations" I think we can arrange for that to be added automatically to the build flags, it is intended to deal with this before 13 branches.
