| 3 | 1. INTRODUCTION::
|
|---|
| 4 |
|
|---|
| 5 | This collection of scripts, known as jhalfs, strives to create
|
|---|
| 6 | accurate makefiles from the Linux From Scratch book series XML files.
|
|---|
| 7 | This software is an evolution of the original "jhalfs-0.2" code.
|
|---|
| 8 |
|
|---|
| 9 | The usage of this script assumes you have read and are familiar with
|
|---|
| 10 | the book(s) and, therefore, the configuration variables found in config
|
|---|
| 11 | files will have meaning to you. There are a number of command line switches
|
|---|
| 12 | which, if used, will override the config file settings.
|
|---|
| 13 |
|
|---|
| 14 | NOTES::
|
|---|
| 15 | *. The resulting Makefile takes considerable time to run to completion.
|
|---|
| 16 | Lay in a supply of caffeine beverages.
|
|---|
| 17 |
|
|---|
| 18 | *. It is recommended that you temporarily unpack your linux kernel,
|
|---|
| 19 | run <make menuconfig>, configure the kernal as per the book and save
|
|---|
| 20 | the resulting .config file. This suggestion also applies to the
|
|---|
| 21 | configuration of the uClibc package when building a HLFS system using
|
|---|
| 22 | uClibc rather than glibc.
|
|---|
| 23 |
|
|---|
| 24 | 2. INSTALLATION::
|
|---|
| 25 | No installation is required. System-wide installation is not allowed
|
|---|
| 26 | for now.
|
|---|
| 27 |
|
|---|
| 28 | 3. CONFIGURATION FILES::
|
|---|
| 29 | Each book in the LFS series has its own set of configurable parameters
|
|---|
| 30 | as well as the common parameters file.
|
|---|
| 31 |
|
|---|
| 32 | 4. RUNNING::
|
|---|
| 33 | The script master.sh cannot be invoked directly but only via the
|
|---|
| 34 | supplied symlinks. After editing the config file for the project you wish
|
|---|
| 35 | to build, run the script.
|
|---|
| 36 |
|
|---|
| 37 | The term <symlink> refers to the 1 of 4 package symlinks, lfs,hlfs,clfs,blfs.
|
|---|
| 38 | Replace <symlink> with your choice of packages; i.e.: ./lfs
|
|---|
| 39 |
|
|---|
| 40 | ./<symlink>
|
|---|
| 41 | Create a makefile based on the settings found in the config files.
|
|---|
| 42 | You must enter the build partition/jhalfs directory and manually run <make>
|
|---|
| 43 |
|
|---|
| 44 | ./<symlink> -G
|
|---|
| 45 | Download the packages and patches necessary to build <symlink>
|
|---|
| 46 |
|
|---|
| 47 | ./<symlink> -G -M
|
|---|
| 48 | Download the packages, create and automatically run the Makefile
|
|---|
| 49 |
|
|---|
| 50 | ./<symlink> --help will give you a context sensitive list of command
|
|---|
| 51 | line switches.

|
|---|
| 76 | Q. "It doesn't work"
|
|---|
| 77 | A. Yes it does..
|
|---|
| 78 |
|
|---|
| 79 | Q. "How do I specify the build location"
|
|---|
| 80 | A. The original LFS document worked against the well know location /mnt/lfs.
|
|---|
| 81 | This script automates the build of all of the LFS series of books and uses
|
|---|
| 82 | a generic location $BUILDDIR with a default value a /mnt/build_dir.
|
|---|
| 83 | You may change this value to suit your needs.
|
|---|
| 84 |
|
|---|
| 85 | The layout below $BUILDDIR is as follows.
|
|---|
| 86 | $BUILDDIR/
|
|---|
| 87 | jhalfs (makefile,cmd scripts,logs..etc)
|
|---|
| 88 | sources (where packages reside
|
|---|
| 89 | temptools (temporary bootstrap system
|
|---|
| 90 | cross-tools (CLFS only)
|
|---|
| 91 | ...
|
|---|
| 92 | FHS dir structure
|
|---|
| 93 | ...
|
|---|
| 94 |
|
|---|
| 95 | Q. "What is the function of the SRC_ARCHIVE variable
|
|---|
| 96 | A. When then symlinked master.sh runs it creates a local copy of the
|
|---|
| 97 | necessary packages in BUILDDIR/sources by downloading the files. If
|
|---|
| 98 | the variable SRC_ARCHIVE is defined the software will first look in
|
|---|
| 99 | this location for the file and, if found, will copy it to BUILDDIR/sources.
|
|---|
| 100 | If the files are not found in SRC_ARCHIVE _and_ you have write priv to
|
|---|
| 101 | the directory any downloaded files will be mirrored there.
|
|---|
| 102 |
|
|---|
| 103 | Q. "How do I set the SRC_ARCHIVE location"
|
|---|
| 104 | A. The best way to set the value of SRC_ARCHIVE is
|
|---|
| 105 | export SRC_ARCHIVE=/wherever/you/store/downloaded/packages
|
|---|
| 106 | OR
|
|---|
| 107 | you can change the setting in .common/config.
|
|---|
| 108 |
|
|---|
| 109 | Q. "Why have 2 copies of the files."
|
|---|
| 110 | A. The package files must be visible during the chroot phase and this is a
|
|---|
| 111 | simple and reliable method of doing so. This method also handles the CLFS
|
|---|
| 112 | build method where the final build may be done on a separate machine.
