  Installation instructions for the HFS Filesystem for Linux

  This document explains how to compile and install version 0.95 of
  hfs_fs, the HFS filesystem for Linux.

  11..  SSyysstteemm RReeqquuiirreemmeennttss

  You will need the following to compile and use this release of hfs_fs:

  +o  Kernel version 2.0.1 or newer compiled with modules enabled
     (CONFIG_MODULES).

  +o  The kernel sources (or at least the header files) available online.

  +o  The module utilities package current for your kernel version and an
     understanding of how to use it.  (The file
     Documentation/modules.txt in the kernel source directory provides a
     brief introduction.)

  22..  IInnssttaallllaattiioonn

  This release of the HFS filesystem is not part of the official kernel
  distribution.  Therefore, it is compiled as a module and then loaded
  into the kernel using the module utilities.  Therefore, your kernel
  must be compiled with CONFIG_MODULES enabled.

  22..11..  CCoommppiilliinngg tthhee llooaaddaabbllee mmoodduullee

  To compile hfs.o you should only need to execute ``make'' in the
  hfs_fs source directory.

  If gcc complains about not finding a large number of header files with
  names beginning with ``linux/'' then you probably don't have the
  kernel header files installed correctly.  Either /usr/include/linux,
  /usr/include/asm and /usr/include/scsi should be symbolic links to
  include/linux, include/asm and include/scsi in the kernel source tree
  for the kernel you wish to use hfs_fs with, or else they should be
  directories containing the header files for the kernel you wish to use
  hfs_fs with.

  If gcc complains about not finding linux/version.h, then you will need
  to run ``make dep'' in the kernel source directory to build it.  Under
  MkLinux, run ``make include/linux/version.h'' instead.

  If gcc complains about not finding the files linux/config.h or
  linux/autoconf.h, then you will need to run ``make config'' and ``make
  dep'' in the kernel source directory to build these two files.

  If you are compiling on a DEC Alpha and receive messages saying
  assignment from incompatible pointer type when compiling files dir_*.c
  and file_*.c, then you need to change a single line in the file
  linux/hfs_fs.h.  Remove the text ``&& !defined(__alpha__)'' from the
  end of line 217.

  If you plan to use kerneld to automatically load the module or if you
  wish to use modprobe or insmod without supplying a complete path to
  hfs.o, then you will need to copy hfs.o into a directory where the
  module utilities expect to find it.

  The proper directory may depend slightly on your configuration.
  However, /lib/modules/default/fs/ is a common one for filesystem
  modules.  Once hfs.o is in the proper directory you should run depmod
  -a to update the dependency list used by kerneld and modprobe.

  22..33..  LLooaaddiinngg tthhee mmoodduullee iinnttoo tthhee rruunnnniinngg kkeerrnneell

  There are three ways to accomplish this:

  1. If you are running kerneld and have installed hfs.o in the modules
     directory then you don't need to issue any commands; the module
     will be loaded when you attempt to mount an HFS filesystem.

  2. If you are _n_o_t running kerneld then you can load hfs.o manually by
     running modprobe hfs.o.  If you have not installed hfs.o in one of
     the standard module directories, then you will need provide a full
     path to the file hfs.o.

  3. If you have been experiencing kernel crashes with hfs_fs, then you
     should file a bug report including the names of the functions which
     the EIP and Stack Trace point into.  To help with this you can ask
     for relocation map for the module when you load it.  To do this
     load the module with ``insmod -m hfs.o >loadmap''.  Again, you may
     need a full path to the file hfs.o if you have not placed it in one
     of the standard module directories.

  22..44..  UUssiinngg tthhee mmoodduullee wwiitthh vveerrssiioonneedd ssyymmbboollss

  All the interface between the module and the kernel take place through
  very stable (since the mid-1.3.x kernels) parts of the kernel.  If you
  enabled versioned symbols (CONFIG_MODVERSIONS) when you compiled your
  kernel you should often be able to compile this module once and then
  use it with many kernels newer than the one you compiled it for.

  In any case, it is unlikely that this module will need changes with
  each new kernel patch; simple recompilation should usually suffice.
