If I grep correctly, rpi4 is ARMv8-A. Yet you're compiling with -march=armv8.2-a, so it's a case of wrong -march.

Hi, Thank you for the quick insight. Now I found this update upstream: https://jira.mongodb.org/browse/SERVER-55178 and https://github.com/mongodb/mongo/commit/8f708f3b68c3c85108294a8f58d780b6ccf18194 . Not much info why this was necessary though. I hate it when a commit message describes *what* changed instead of *why* it changed. The what is already in the diff. Anyways. Thanks for the reply. I think I'll need to try to contact somebody at MongoDB. Regards, Ronald. _______________________________________________ freebsd-ports@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"
