| 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 developed
|
|---|
| 8 | by Jeremy Huntwork.
|
|---|
| 9 |
|
|---|
| 10 | The usage of this script assumes you have read and are familiar with
|
|---|
| 11 | the book(s) and, therefore, the configuration variables found in menuconfig
|
|---|
| 12 | interface will have meaning to you.
|
|---|
| 13 |
|
|---|
| 14 | The list of supported books can be found at
|
|---|
| 15 | http://wiki.linuxfromscratch.org/alfs/wiki/SupportedBooks
|
|---|
| 16 |
|
|---|
| 17 | NOTES::
|
|---|
| 18 | *. The resulting Makefile takes considerable time to run to completion.
|
|---|
| 19 | Lay in a supply of caffeine beverages.
|
|---|
| 20 |
|
|---|
| 21 | *. It is recommended that you temporarily unpack your linux kernel,
|
|---|
| 22 | run <make menuconfig>, configure the kernel as per the book and save
|
|---|
| 23 | the resulting .config file. This suggestion also applies to the
|
|---|
| 24 | configuration of the uClibc package when building a HLFS system using
|
|---|
| 25 | uClibc rather than glibc.
|
|---|
| 26 |
|
|---|
| 27 | *. Read carefully this file and the other README.* files before start
|
|---|
| 28 | using the tool.
|
|---|
| 29 |
|
|---|
| 30 | 2. PREREQUISITES::
|
|---|
| 31 |
|
|---|
| 32 | To use this tool you MUST:
|
|---|
| 33 |
|
|---|
| 34 | - have experience building {c,h,b}LFS packages
|
|---|
| 35 | - know how to edit and write shell scripts
|
|---|
| 36 | - know how a Makefile works
|
|---|
| 37 | - be able to trace build failures and to find what is causing it
|
|---|
| 38 | (user error, package bug, {c,h,b}LFS command bug, or jhalfs code bug)
|
|---|
| 39 |
|
|---|
| 40 | If you do not have the above skills, please don't use this tool.
|
|---|
| 41 |
|
|---|
| 42 |
|
|---|
| 43 | 3. INSTALLATION::
|
|---|
| 44 |
|
|---|
| 45 | No installation is required. System-wide installation is not allowed.
|
|---|
| 46 |
|
|---|
| 47 | 4. CONFIGURATION::
|
|---|
| 48 |
|
|---|
| 49 | ::NEWS::
|
|---|
| 50 | There is a new configuration method for jhalfs.
|
|---|
| 51 |
|
|---|
| 52 | We have installed the familiar menu based configuration tool driven by
|
|---|
| 53 | GNU make. see the section RUNNING, for details
|
|---|
| 54 |
|
|---|
| 55 | 5. RUNNING::
|
|---|
| 56 |
|
|---|
| 57 | ::NEWS::
|
|---|
| 58 | jhalfs is now launched via GNU make instead of individual symlinks.
|
|---|
| 59 |
|
|---|
| 60 | The command <make> will launch a menu based configuration program. You will
|
|---|
| 61 | recognize the layout from building the kernel or uClibc/BusyBox. The
|
|---|
| 62 | underlying menu code was borrowed from BusyBox and slightly modified for
|
|---|
| 63 | our use.
|
|---|
| 64 |
|
|---|
| 65 | Help on parameter function is available from the on-line help. Please
|
|---|
| 66 | make use of that feature for additional information not in this file.
|
|---|
| 67 |
|
|---|
| 68 | Once you have set the parameters you wish and have saved your work the
|
|---|
| 69 | jhalfs script is launch. The script verify first that the host can run
|
|---|
| 70 | it and build the xLFS system, then validate the configuration and present
|
|---|
| 71 | you with your selections which you may accept or reject.
|
|---|
| 72 |
|
|---|
| 73 | If you accepted the displayed settings jhalfs will proceed to create the
|
|---|
| 74 | Makefile, optionally download packages.
|
|---|
| 75 |
|
|---|
| 76 | ::NEWS::
|
|---|
| 77 | You must be logged as a normal user with sudo privileges to run
|
|---|
| 78 | the Makefile.
|
|---|
| 79 |
|
|---|
| 80 | NOTE::
|
|---|
| 81 | If you run the jhalfs script directly the only function you can select
|
|---|
| 82 | is to display the version number running <./jhalfs -v>
|
|---|
| 83 |
|
|---|
| 84 | 6. BLFS_TOOL SUPPORT::
|
|---|
| 85 |
|
|---|
| 86 | For books that support it, there is an option to install blfs-tool and its
|
|---|
| 87 | dependencies on the final system. The pre-made build dependencies
|
|---|
| 88 | scripts has been written thinking on a LFS build. For CLFS and HLFS
|
|---|
| 89 | builds you may need to adjust that scripts, that are found into the
|
|---|
| 90 | common/blfs-tool-deps directory in the jhalfs sources tree.
|
|---|
| 91 |
|
|---|
| 92 | WARNING:: If adding blfs-tool support on a CLFS Sysroot build
|
|---|
| 93 | you MUST to edit the dependencies scripts to fix the
|
|---|
| 94 | installation paths.
|
|---|
| 95 | Be sure to make the adjust carefully or you will end
|
|---|
| 96 | messing your host system.
|
|---|
| 97 |
|
|---|
| 98 | After booting the new xLFS system some steps are needed to finish
|
|---|
| 99 | blfs-tool installation:
|
|---|
| 100 |
|
|---|
| 101 | - A user account must be created. You must be logged on that user
|
|---|
| 102 | account to use blfs-tool.
|
|---|
| 103 |
|
|---|
| 104 | - Move /blfs-root to that user's home and change ownership of the
|
|---|
| 105 | directory and files to the user.
|
|---|
| 106 |
|
|---|
| 107 | - Give the user read and write privileges over the $TRACKING_DIR
|
|---|
| 108 | directory and the files that it contains.
|
|---|
| 109 |
|
|---|
| 110 | - Configure sudo, adding the needed privileges for the user.
|
|---|
| 111 |
|
|---|
| 112 | We assume that blfs-tool will be used on a running fresh xLFS system.
|
|---|
| 113 | To use it to build BLFS packages from the chroot jail is also possible,
|
|---|
| 114 | but is for you to figure out how to do that.
|
|---|
| 115 |

| 181 | 8. FAQ::
|
|---|
| 182 | Q. "This 'help' file is very sparse"
|
|---|
| 183 | A. Yes, it is. This tool, jhalfs, is for those who understand the LFS books
|
|---|
| 184 | and wish to automate the build. 99% of any problems that arise can be
|
|---|
| 185 | solved by reading the book(s).
|
|---|
| 186 |
|
|---|
| 187 | Q. "It doesn't work!"
|
|---|
| 188 | A. Yes it does, try >> make
|
|---|
| 189 | Remember you must have 'sudo' privileges.
|
|---|
| 190 |
|
|---|
| 191 | Q. "It still doesn't work"
|
|---|
| 192 | A. jhalfs was designed to work against the development versions of the LFS
|
|---|
| 193 | series of books. Consequently changes in a book(s) sometimes breaks older
|
|---|
| 194 | versions of jhalfs. Before you start pulling out your hair download the
|
|---|
| 195 | latest version of jhalfs to see if that solves your problem.
|
|---|
| 196 |
|
|---|
| 197 | Q. "How do I specify the build location?"
|
|---|
| 198 | A. The original LFS document worked against the well known location /mnt/lfs.
|
|---|
| 199 | This script automates the build of all of the LFS series of books and uses
|
|---|
| 200 | a generic location $BUILDDIR with a default value of /mnt/build_dir.
|
|---|
| 201 | You may change this value to suit your needs.
|
|---|
| 202 |
|
|---|
| 203 | The layout below $BUILDDIR is as follows.
|
|---|
| 204 | $BUILDDIR/
|
|---|
| 205 | jhalfs (Makefile, cmd scripts, logs, etc..)
|
|---|
| 206 | sources (where packages reside)
|
|---|
| 207 | tools (temporary bootstrap system)
|
|---|
| 208 | cross-tools (temporary CLFS only)
|
|---|
| 209 | ...
|
|---|
| 210 | FHS dir structure
|
|---|
| 211 | ...
|
|---|
| 212 | blfs_root (files to use blfs-tool if selected to install it)
|
|---|
| 213 |
|
|---|
| 214 | Q. "What is the function of the SRC_ARCHIVE variable?"
|
|---|
| 215 | A. When jhalfs runs and packages download was selected, it creates a local
|
|---|
| 216 | copy of the necessary packages in BUILDDIR/sources by downloading the
|
|---|
| 217 | files. If the variable SRC_ARCHIVE is defined the software will first
|
|---|
| 218 | look in this location for the file and, if found, will copy it to
|
|---|
| 219 | BUILDDIR/sources.
|
|---|
| 220 | If the files are not found in SRC_ARCHIVE _and_ you have write priv to
|
|---|
| 221 | the directory any downloaded files will be mirrored there.
|
|---|
| 222 |
|
|---|
| 223 | Q. "How do I set the SRC_ARCHIVE location?"
|
|---|
| 224 | A. The best way to set the value of SRC_ARCHIVE is
|
|---|
| 225 |
|
|---|
| 226 | export SRC_ARCHIVE=/wherever/you/store/downloaded/packages
|
|---|
| 227 |
|
|---|
| 228 | or you can set the full path in the proper menu entry.
|
|---|
| 229 |
|
|---|
| 230 | Q. "Why have 2 copies of the files?"
|
|---|
| 231 | A. The package files must be visible during the chroot phase and this is a
|
|---|
| 232 | simple and reliable method of doing so. This method also handles the CLFS
|
|---|
| 233 | boot build method where the final build may be done on a separate machine.
|
|---|
| 234 |
|
|---|
| 235 | Q. "What is the function of "User account" and "Group account" menu settings?"
|
|---|
| 236 | A. If you are running jhalfs from a low or non-privileged account you may not
|
|---|
| 237 | have the priv to create/delete the user needed to build temporary tools.
|
|---|
| 238 | These settings allow you to use your own user and group name to do that
|
|---|
| 239 | build steps.
|
|---|
| 240 |
|
|---|
| 241 | These variables are adjustable also when invoking make:
|
|---|
| 242 |
|
|---|
| 243 | $BUILDDIR make LUSER=myaccount LGROUP=mygroup
|
|---|
| 244 |
|
|---|
| 245 | The only changes to your account will be the creation of a NEW .bashrc
|
|---|
| 246 | after saving your original to .bashrc.XXX
|
|---|
| 247 |
|
|---|
| 248 | Q. "When I try to build CLFS the Makefile fails at the mid-point"
|
|---|
| 249 | A. There could be numerous reasons for the failure but the most likely reason
|
|---|
| 250 | is you are doing a cross-build using the 'chroot' method and the target is
|
|---|
| 251 | not compatible with the host. If you choose to build using the chroot
|
|---|
| 252 | method a test is performed at the end of the temptools phase. If the test
|
|---|
| 253 | succeeds the build continues inside a chroot jail. However if the test fails
|
|---|
| 254 | it means the host and target are not compatible an you should use the
|
|---|
| 255 | 'boot' method to create your target code.
|
|---|
| 256 | As an extreme example: You can build a sparc target on a x86 platform but
|
|---|
| 257 | only the temptools phase. You must select the 'boot' method and not the
|
|---|
| 258 | 'chroot.' You must transfer the toolchain to a sparc platform, reboot the
|
|---|
| 259 | sparc box and continue the build.
|
|---|
| 260 | Of all the LFS series of books Cross-LFS requires the greatest
|
|---|
| 261 | understanding of host/target hardware combination. Please read the book
|
|---|
| 262 | carefully and don't skip the easy parts (there are none..)
|
|---|
| 263 |
|
|---|
| 264 | Q. "How could I stop the build at a predefined chosen point?"
|
|---|
| 265 | A. Launch the Makefile manually passing the last numbered target to be build
|
|---|
| 266 | as the break point. For example:
|
|---|
| 267 |
|
|---|
| 268 | make BREAKPOINT=84-bash
|
|---|
| 269 |
|
|---|
| 270 | The build can be stopped also at the end of a top-level build phase by
|
|---|
| 271 | calling directly the appropriate mk_* target. For example:
|
|---|
| 272 |
|
|---|
| 273 | make mk_LUSER
|
|---|
| 274 |
|
|---|
| 275 | See the Makefile to know the proper target names for that book build.
