1. INTRODUCTION::
|
|
|
|
To automatize packages build from the BLFS book instructions is a huge
|
|
task. The BLFS book isn't linear, some package pages need to use a non
|
|
defaul layout, there are circular dependencies, several packages can be
|
|
installed on a non default prifix, build commands can change based on what
|
|
dependencies will be used, etc.
|
|
|
|
Said that, the goal of jhalfs is try to help you solving packages
|
|
dependencies and creating your own build scripts/Makefile. Some of the
|
|
auto-generated build scripts and Makefile could work "as is", but as a
|
|
general rule you will need to review and edit the scripts while reading
|
|
the book.
|
|
|
|
NOTE:: The code is still under development and may contains several bugs
|
|
|
|
|
|
2. USAGE::
|
|
|
|
Due the complexity of the BLFS book, the scripts/Mafile generation is
|
|
done in several steps:
|
|
|
|
2.1 INSTALLATION::
|
|
Run "make" to launch the menuconfig interface. Select the BLFS book
|
|
and it version. Then set the installation directory (default
|
|
$HOME/blfs_root) and the BLFS sources directory (default blfs-xml).
|
|
|
|
All required files will be placed in the installation directory and
|
|
BLFS XML sources will be checkout to the named sub-directory.
|
|
|
|
Installed files:
|
|
|
|
lib/* functions, xsl, and auto-generates dependencies tree files
|
|
README.BLFS this file
|
|
TODO developers notes
|
|
packages auto-generated file with packages info
|
|
alternatives.conf configuration files for alternative packages
|
|
makefile.conf envars needed when running the generated Makefile
|
|
update_book.sh update the XML book sources and regenerate packages file
|
|
and GNOME and KDE dependencies tree
|
|
blfs-parser.sh generates linear BLFS books and build scripts
|
|
gen-makefile.sh generates Makefile
|
|
progress_bar.sh the Makefile progress bar
|
|
|
|
From now on, all the work must be done from inside the installation
|
|
root directory.
|
|
|
|
2.2 UPDATING BOOK SOURCES::
|
|
If using the SVN book version, from time to time you may want to update
|
|
the XML sources. To do that run "./update_book.sh"
|
|
|
|
2.3 PARSING THE BOOK::
|
|
Next step is to create a book and build scripts in dependencies build order
|
|
for a target package. A target package can be any of the ones listed in the
|
|
packages file. That is done using the blfs-parser.sh script, but we are trying
|
|
to make a menuconfig based system.
|
|
|
|
The script need three arguments:
|
|
|
|
package name as listed in packages file
|
|
dependencies level 1 for required,
|
|
2 for required an recommendedand,
|
|
3 for required, recommended, and optional
|
|
sudo usage y if sudo will be used (you will build as normal user)
|
|
n if sudo isn't needed (you will build as root)
|
|
|
|
For example:
|
|
|
|
./blfs-parser galeon 3 y
|
|
|
|
will create a directory named "galeon". Inside that directory you find a
|
|
directory named "HTML" that contains a galeon-based HTML book with all
|
|
dependencies in build order and a "scripts" directory with build scripts
|
|
that uses sudo for commands that need root priviledges.
|
|
|
|
There is also two other directories that contains files generated while
|
|
resolving dependencies trees.
|
|
|
|
Now is the time to review the generated book and scripts, making in the
|
|
scripts any changes you want to fit your needs. Scripts for aditional
|
|
packages (i.e., for non-BLFS packages) can be inserted in an easy way.
|
|
|
|
2.4 CREATING THE MAKEFILE
|
|
When the build scripts are ready to be run, the Makefile can be
|
|
created. Be sure that you cd into the "package" directory and run
|
|
|
|
../gen_makefile.sh
|
|
|
|
Review the Makefile and if all look sane, start the build.
