Mostly,
OSVERSION=
UNAME_m=
UNAME_p=
UNAME_r=
UNAME_s=
UNAME_v=
then chroot or jail. I have a script:
#!/bin/sh
UNAME_s="FreeBSD"
UNAME_m="i386"
UNAME_p="i386"
ROOT=$HOME/current_$UNAME_p
REVISION=`cd ${ROOT}/sys/conf && grep REVISION= newvers.sh | cut -f2 -d'"'`
BRANCH=`cd ${ROOT}/sys/conf && grep BRANCH= newvers.sh | head -n1 | cut -f2 -d'
"'`
UNAME_r=$REVISION-$BRANCH
UNAME_v="$UNAME_s $UNAME_r #0: Thu May 4 07:54:55 PDT 2006 root@a21p:/data/
home/ambrisko/current/usr/src/sys/$UNAME_p/compile/THINK"
OSVERSION=`awk '/\#define.*__FreeBSD_version/ { print $3 }' < ${ROOT}/sys/sys/pa
ram.h`
export UNAME_s UNAME_r UNAME_v UNAME_m UNAME_p OSVERSION ROOT
if [ -r $ROOT/dev/zero ]
then
echo dev already mounted
else
sudo mount -t devfs dev $ROOT/dev
fi
sudo ln -sf ld-elf.so.1 $ROOT/libexec/ld-elf32.so.1
sudo sh -c '( echo "libpthread.so.2 libthr.so.2" ;\
echo "libpthread.so libthr.so") > ${ROOT}/etc/libmap.conf'
sudo cp ${ROOT}/etc/libmap.conf ${ROOT}/etc/libmap32.conf
sudo chroot $ROOT
It could be made even smarter but looking at the dest and figuring out
the release as well.
We could make it a make target since you can do this into 6.2 world as
well (amd64/current -> amd64/6.2, amd64/current -> i386/6.2 or
amd64/current -> amd64/i386). I think I merged in the UNAME_/OSVERSION
stuff before 6.2 went out. I also have local hacks to do this with 4.X.
At work, our build machines are all loaded up with amd64 and we build
i386 or amd64 SW on them. This includes whatever ports are needed.
