Bless you.  I just built an arm kernel!

That compiler is *fast*.  47 seconds.  Weird.

For reference, untar the above in / and use


#!/bin/sh
export ARCH=arm
export CROSS_COMPILE=arm-linux-
W=/usr/local/arm/oe/bin

MAKE="make"

if [ -z "$1" ]
then
	WHAT="vmlinux"
else
	WHAT="$1"
fi

nr_cpus=$(grep processor /proc/cpuinfo|wc -l)
j=$(expr $nr_cpus \* 3 / 2)

MAKE_ARGS="ARCH=$ARCH CROSS_COMPILE=$W/arm-linux-"

if [ x"$DISTCC_HOSTS" != x ]
then
	$MAKE -j 12 CC="ccache distcc --ccache-skip $W/$CROSS_COMPILE""gcc" $MAKE_ARGS $WHAT 2>/tmp/log
else
	$MAKE -j $j $MAKE_ARGS CC="$W/$CROSS_COMPILE""gcc" $WHAT 2>/tmp/log
fi
cat /tmp/log


That's now eight architectures I'll compile-test mm kernels on.
