I built & installed world/kernel with -O -pipe, then later tried to make kernel with just -pipe and it failed (with or without debug)... I guess if I buildworld with -O I must build my kernel with -O. Is there any problem getting info out of a crashdump if the kernel is compiled -O (along with -g) Now that I've restored the -O, a debug GENERIC builds just fine. I had no idea that I could not mix -O and non -O code... sorry about that. - Tim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
