How hard would it be to force CC/CXX to /usr/bin/false during installworld? Trivial in FreeBSD. Just make it so in Makefile for the installworld target, add false to itools, and add appropriate special casing in bsd.compiler.mk. Doing this just prevents recompiling though, so not pjd's case. Also, this might break someone's random usecase where they need CC/CXX to do something meaningful at install time, however, the likelihood of it being correct is slim IMHO.. ___ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org
