If you define WITHOUT_GCC, a cc isn't created in /usr/obj/usr/src/tmp/usr/bin but if you go into the directory and do a symbolic link from clang, and restart make with -DNO_CLEAN it'll work and complete. One of the programs hardcodes cc and doesn't check the environment, I forget which. Built the code until it failed. Then did a `ln -s /usr/obj/root/src/tmp/usr/bin/clang /usr/obj/root/src/tmp/usr/bin/cc` and a `make -DNO_CLEAN -j12 buildworld` and it finished just fine.

Where and when /etc/fstab is checking during boot
I've just finished working though building a FreeBSD box with an encrypted root partition as mentioned in the geli(8) man page: "Ask for the passphrase on boot, before the root partition is mounted. This makes it possible to use an encrypted root partition. One will still need bootable unencrypted storage with a /boot/ directory, which can be a CD-ROM disc or USB pen-drive, that can be removed after boot." I've noticed something quite interesting about the way that fstab is read during boot. If you follow the instructions exactly as they are written in the geli(8) man page you soon discover that you also must have an /etc/fstab file in that same unencrypted partition. But this need not be the complete fstab file. It only needs to have the one line that describes /. Later, after the encrypted partition is mounted, the /etc/fstab inside the encrypted partition is then read and all other partitions listed in fstab are mounted as written there. I've tested this by putting empty fstabs and fstabs with just the line for / in both locations and booting to see what happens. Is this the correct behavior? Shouldn't the fstab file be read completely once and not twice? ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
Never forget a special trick - Asking for the real information
Dear anonymous open-source enthusiasts friends, Nevermind my previous question and please forget that this list is a place for any ingenuous subject. I believe I have followed the instructions searching for answers before asking for help. But the information I'm looking for surely isn't found by using apropos or man -k or even grep -ir. So... Anybody already noticed the PID numbers from ps output increasing too much? And after rebooting several times You realize that You are not alone? Then You give up and simple watch the console messages talking with you? But there's no prompt to login or to run a shell, only the cursor blinking! You literally matrix out with others true rail transport modellers... really? They talk about magic and utopia and You learn something special... very special! The end. Enough said, I just forgot the escape sequences to authenticate as console operator. Yes, I admit I failed to my first lesson and I don't deserve any second chances. If You think that magic and utopia I just said isn't truth, maybe we are on the same boat forever. Otherwise just follow the book, Phillip. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"

Thank you very much for the kind words. That's very nice to hear. Yes, I'm quite pleased myself with how the program turned out. Honestly, though, I never expected the performance difference to be nearly as dramatic as it turned out to be. :-) Apparently, though, there's a latent bug in the program that only crops up under certain conditions. Just discovered it this morning. Working on a fix. Also, Marco Steinbach has reported that the program won't run in a jail environment, due to the attempt to elevate the program's priority setting. Note to hackers: what is the recommended method for determining if a process is running in a jail? I've been thinking of using sysctl(), but wondering if there's a better way. Getting to work on it today. Hope to have a new version to submit very soon. Conrad -- Conrad J.
