[I've cut the history.] I've tried a from-scratch build via the script: # more = ~/sys_build_scripts.amd64-host/make-aarch64-debug-clang-default_config-amd= 64-host.sh kldload -n filemon && \ script = ~/sys_typescripts/typescript_make_aarch64_debug_clang_default_config-amd64= -host-$(date +%Y-%m-%d:%H:%M:%S) \ env __MAKE_CONF=3D/dev/null SRCCONF=3D/dev/null SRC_ENV_CONF=3D/dev/null = TARGET=3Darm64 TARGET_ARCH=3Daarch64 \ WITH_META_MODE=3Dyes \ = MAKEOBJDIRPREFIX=3D"/usr/obj/aarch64dbg_default_config_clang/arm64.aarch64= " \ make $* on my existing source context ( 19cca0b9613d with CommitDate 2021-01-09 16:21:33 -0800=20 based ): # ~/fbsd-based-on-what-freebsd-main.sh mm-src 19cca0b9613d7c3058e41baf0204245119732235 CommitDate: 2021-01-09 16:21:33 -0800 5d333ee67ac3 19cca0b9613d (HEAD -> mm-src) mm-src snapshot for mm's = patched build in git context. So defaults but for TARGET, TARGET_ARCH, WITH_META_MODE, and MAKEOBJDIRPREFIX . WITH_META_MODE should not matter for a from-scratch build as far as I know. This is still a cross-build context. I used the 3 commands: = ~/sys_build_scripts.amd64-host/make-aarch64-debug-clang-default_config-amd= 64-host.sh -j32 kernel-toolchain = ~/sys_build_scripts.amd64-host/make-aarch64-debug-clang-default_config-amd= 64-host.sh -j32 buildkernel = ~/sys_build_scripts.amd64-host/make-aarch64-debug-clang-default_config-amd= 64-host.sh -j32 installkernel = DESTDIR=3D/usr/obj/DESTDIRs/clang-aarch64-installkernel-dbg-default_config= (I'll avoid documenting copying to the RPi4B /boot/kernel/ and such.)
