FYI: Historically unless something extreme like this ends up involved I build everything using WITH_DEBUG= or explicit -g's in order to have better information on any failure. This is extreme enough that next time I synchronize /usr/ports and it has a devel/llvm40 update I'll likely rebuild devel/llvm40 without using WITH_DEBUG= . I'm more concerned with the time it takes than with the file system space involved. === Mark Millard markmi at dsl-only.net _______________________________________________ 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"
