The good news: I just successfully completed a build and install of =
FreeBSD/arm with clang 3.8.0.:
FreeBSD 11.0-CURRENT #0 r296611: Sun Mar 13 03:18:03 EDT 2016
pmather@beaglebone:/usr/obj/usr/src/sys/BEAGLEBONE-NO_WITNESS arm
FreeBSD clang version 3.8.0 (tags/RELEASE_380/final 262564) (based on =
LLVM 3.8.0)
Everything appears to be working fine so far. :-)
The bad news: this appears to have added 24 hours to my build time (from =
41 to 65 hours for a native build). :-(
To try and cut down future build times, I tried enabling =
WITH_DIRDEPS_BUILD in /etc/src-env.conf. Unfortunately, this fails =
immediately with a complain that /dev/filemon is not available:
root@beaglebone:/usr/src # make buildworld
make: "/usr/src/share/mk/meta.sys.mk" line 120:
ERROR: The filemon module (/dev/filemon) is not loaded.
My reading of the src.conf man page leads me to believe /dev/filemon is =
optional with the WITH_DIRDEPS_BUILD option:
WITH_DIRDEPS_BUILD
Enable building in meta mode. This is an experimental =
build
feature. For details see =
http://www.crufty.net/sjg/docs/freebsd-
meta-mode.htm.
[[...]]
As each target is made make(1) produces a meta file which =
is used
to capture (and compare) the command line, as well as any =
command
output. If filemon(4) is available the meta file will also
capture a record of files used to produce the target by =
tracking
syscalls.
[[...]]
Is this in fact the case?
I have a filemon man page but no /dev/filemon. I can't load the filemon =
kernel module:
root@beaglebone:/usr/src # kldload -v filemon
kldload: can't load filemon: No such file or directory
There is no filemon.ko in /boot/kernel.
It appears filemon is not built by default in the regular FreeBSD/arm =
build. Is this an oversight, or is it because it doesn't work on =
FreeBSD/arm?
Has anyone used a meta-mode build on FreeBSD/arm?
Cheers,
Paul.=
