https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=210993 Bug ID: 210993 Summary: 11.0 WITH_META_MODE cross builds have "Exec format error" problems when certain areas attempt a rebuild Product: Base System Version: 11.0-BETA1 Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: misc Assignee: freebsd-bugs@FreeBSD.org Reporter: markmi@dsl-only.net For using WITH_META_MODE=yes again for going from -r302331 to -r302412 via cross builds amd64 -> armmv6 or powerpc64: The build stopped with: --- init_keytry.h --- sh: ./make_keys: Exec format error *** [init_keytry.h] Error code 126 Using a worldclean and then separately a buildworld was sufficient to get around the problem. Past exchanges also reported: > --- proctab.c --- > sh: ./maketab: Exec format error > *** [proctab.c] Error code 126 But this only happened if one got by the make_keys one. I've not seen this one recently but the worldclean may be avoiding it too. I only remember the two examples [make_keys and maketab] being found as having the issue but there could be more as far as I know. At one time at least the maketab one was believed fixed after -r301884 (2016-Jun-14 or so). I expect "Exec format error" is an issue in certain areas whenever TARGET_ARCH is incompatible with the host architecture. amd64 -> armv6/powerpc64 are just the examples from my environment. Prior activity ends up leaving the incompatible file(s) where later rebuilds try to use them on the host. If it turns out that WITH_META_MODE=yes rebuilding a cross build does not execute make_keys or maketabs [or . . .?] then it works fine. At least is what I expect is the reason that some of my WITH_META_MODE=yes cross-rebuilds have had no problems. It may be that UPDATING for 11.0-RELEASE and 11.0-STABLE and the like just will need notes something like the following for now: "If you run into 'Exec format error' during a WITH_META_MODE=yes rebuild for a cross build (TARGET_ARCH=. . .) then you will need to do a make worldclean and then another buildworld (and possibly build kernel) for the TARGET_ARCH. An alternative is to not use WITH_META_MODE=yes ." -- You are receiving this mail because: You are the assignee for the bug.
