Okay. I was just looking for a way to deal with local experimental patches in the system and/or ports rather than building from official materials, checking how things seem to go for builds. I ended up with the following nxb* directories in /usr/obj/. . . for my context: /usr/obj/powerpc.powerpc/nxb /usr/obj/arm.armv6/nxb /usr/obj/arm64.aarch64/nxb /usr/obj/DESTDIRs/clang-armv7-installworld-dist-from-src/nxb-bin /usr/obj/DESTDIRs/clang-cortexA53-installworld-dist-from-src/nxb-bin /usr/obj/DESTDIRs/gcc421-powerpc-installworld-dist-from-src/nxb-bin /usr/obj/DESTDIRs/clang-powerpc-installworld-dist-from-src/nxb-bin = /usr/obj/DESTDIRs/clang-powerpc64-altbinutils-installworld-dist-from-src/n= xb-bin /usr/obj/DESTDIRs/clang-cortexA57-installworld-dist-from-src/nxb-bin /usr/obj/powerpc.powerpc64/nxb However, for example, I did the powerpc ones in the order (as an experiment that I did not expect to "work"): /usr/obj/DESTDIRs/clang-powerpc-installworld-dist-from-src/nxb-bin /usr/obj/DESTDIRs/gcc421-powerpc-installworld-dist-from-src/nxb-bin and the second reused the material from the first -x . In other words: the native compiler ended up being based on clang for the later gcc421 based jail attempt. A similar point goes for the pair (in order): /usr/obj/DESTDIRs/clang-cortexA53-installworld-dist-from-src/nxb-bin /usr/obj/DESTDIRs/clang-cortexA57-installworld-dist-from-src/nxb-bin in that the A57 one bound to the prior A53 -x content. I'm not claiming a problem, just something to know to expect to avoid. (My 32-bit powerpc activity has lead to building things based on both compilers because of the kernel build only working for gcc421-based builds. Such odd combinations are likely rare.) >>=20 >> null) >> JAILFS=3Dnone >> FCT=3Dbuild_native_xtools >> ;; >>=20 >> in order to avoid this. >>=20 >> A similar "jail -c" for "-j zrFBSDx64SLarmv7 -a arm.armv6" (and >> -M /usr/obj/DESTDIRs/clang-armv7-installworld-dist-from-src=20 >> in my context) and the later bulk build for it seems to be >> working fine for building lang/gcc7 (as a test).
