I've started an experiment going another direction: an armv7 context with lots of RAM (and faster processing) with a 13 attempting to build a stable/12 . It is via a chroot into an armv7 13 world on a 8 GiByte, 4-core Cortex-A57 based OverDrive 1000 running aarch64 13. Each process should still be limited to what 32-bit systems allow but overall the system is not that limited. I used -j4 . If such still got the error, then there would likely be implications about the error and it would be unlikely that it would work on the RPi2 v1.1 . (But I expect that it will not get the error.) Root owns file system involved and is doing the build. It did report: make[1]: "/usr/fbsd/stable-12-src/Makefile.inc1" line 344: = SYSTEM_COMPILER: libclang will be built for bootstrapping a = cross-compiler. make[1]: "/usr/fbsd/stable-12-src/Makefile.inc1" line 349: = SYSTEM_LINKER: libclang will be built for bootstrapping a cross-linker. I already had a stable-12-src branch from git experiments but the matching worktree was missing despite being still registered. So the worktree recreation was: # git worktree add -f ../stable-12-src stable-12-src Preparing worktree (checking out 'stable-12-src') Updating files: 100% (81363/81363), done. HEAD is now at f4d0bc6aa6b9 MFC r354991-r354992 (by lwhsu) =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
