Just to save you some time, I use the following script to prepare the
installation for an ICA. This is of course based on the gsbuild
scripts by Greg.
#!/bin/sh
#prepICA
usage()
{
printMsg warning "Usage: `basename $0` dir"
exit 1
}
if [ $# -ne 1 ]
then
usage
fi
if [ ! -d "$1" ]
then
usage
fi
DIR=$1
# Remove symlinks
find $DIR -type l | xargs rm -f
# Unzip files
find $DIR -name "*.bz2" | xargs bunzip2 -f
find $DIR -name "*.gz" | xargs gunzip -f
# Extract static libs
for i in $(find $DIR -name "*.a" -not -name libieee.a -not -name libmcheck.a)
do
install -d $i.X || error "Could not create dir $i.X"
pushd $i.X >/dev/null || error "Could not change to $i.X"
ar x $i || error "Could not extract $i"
rm -f $i
popd >/dev/null
done
For the current situation, make an LFS installation as per the current
book and then copy all the files from the LFS partition to /lfs1 on
the host. Repeat installation with the new build order and copy the
files to /lfs2. Then run prepICA /lfs1 && prepICA /lfs2. Then do a
diff on the two directories.
