The only thing I've found is in LINT, and it mentioned nothing about setting it anywhere but in the kernel config :( For instance, since setting KVA_PAGES in the kernel config doesn't cover everything, and, as I've experienced so far, causes some serious problems, would it be better to suggest that someone sets it in make.conf? From a quick perusal of /etc/defaults/make.conf, my guess is that I'd have to set: COPTFLAGS= -O -pipe -DKVA_PAGES=512 -and- CFLAGS= -O -pipe -DKVA_PAGES=512 Will that cover it all, or is there a problem with doing it that way? Or is there a better way of doing this? To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-emulation" in the body of the message
