[Clfs-support] How to use jhalfs to build CLFS.

[code monkey]

Hello

Maybe this is something that you guys already know...  If so, forgive me
stating
the obvious...

You can use jhalfs to build CLFS and it can be a big help.   However, it
does not work
(currently anyway) 'out of the box'.  There are a few extra steps that
you have to do.

First, jhalfs is not able to download the CLFS book for you.   You have to
do that manually and then point jhalfs at your downloaded copy.

Second, there are a couple of patches to jhalfs that you need to download
and
apply.   I submitted these patches to the jhalfs mailing list a while back
but
they haven't been added to it yet.   So, you have to get and apply them
manually.

This is what you have to do.



1) ======= Get a local working copy of the CLFS book.


# Get the CLFS git
git clone git://git.cross-lfs.org/cross-lfs.git
cd cross-lfs

# If you want to build the 1.1.0 release rather than the current work in
# progress version do the next two commands.  Otherwise, skip it.
git branch branchname clfs-1.1.0
git checkout clfs-1.1.0

# 'BOOK' is where you will need to point jhalfs.
cd BOOK
pwd


2) ======= Get the jhalfs source and patches.

Get the current jhalfs code (or instead download the jhalfs 2.3.2
tarball....)

svn co svn://svn.linuxfromscratch.org/ALFS/jhalfs/trunk jhalfs-trunk
cd jhalfs-trunk   (or jhalfs-2.3.2 if using 2.3.2 release)

2a) ==== The needed jhalfs CLFS patches can be found in this email thread:

http://linuxfromscratch.org/pipermail/alfs-discuss/2010-September/thread.html

    (Find the two emails regarding fixes for building CLFS with jhalfs and
     download the attached patches).

3) =================== Apply the jhalfs patches.

cat jhpatch1.txt |patch -Np1
cat jhpatch2.txt |patch -Np1



4) =================== It's ready to go.

Make your clfs dir and start up jhalfs.   In the jhalfs menu, you will need
to
select "Working Copy" for the CLFS book location and specify the directory
(from
above) where you have stored the CLFS book.

mkdir /mnt/clfs
make


jhalfs doesn't build CLFS as smoothly as it builds LFS.   You may have to
nurse
it through a few spots.   But even so, it still reduces the time needed to
do a CLFS build.
