This information is provided primarily for Shorewall developers.
Users are expected to install from pre-built tarballs or packages.
Git Taxonomy
The Shorewall Git tree at Sourceforge serves as the master
repository for Shorewall 4.4 and later versions. It is not possible to
simply export a directory from Git and run the
install.sh script in that directory. A build step is
required to produce a directory that is suitable for the
install.sh script to run in.
My local git repositories are:
trunk (clone of Code)
The development branch of each product is kept here.
Shorewall-core.
Shorewall
Shorewall6
Shorewall-lite
Shorewall6-lite
Shorewall-init
There are also several other directories which are described in
the following sub-sections.
trunk/docs
The stable release XML documents. Depending on the point in the
release cycle, these documents may also apply to the current development
version.
tools (Clone of Tools)
This is where the release and build tools are kept. There are two
subordinate directories:
tools/build
Tools for building and uploading new releases.
tools/web
Tools for publishing web content
web (Clone of Web)
The files from the web site that are maintained in HTML format.
are kept in this directory.
release (Clone of Release)
Added in Shorewall 4.4.22, this directory contains the files that
contain release-dependent information (change.txt, releasenotes.txt,
.spec files, etc). This is actually a symbolic link to ../release which
has its own Git repository.
Build Tools
As described above, the build tools are kept in tools/build. They are described in the
following sections.
setversion
The setversion script updates the version
number in a directory. The script is run with the current working
directory being release.
setversion
version
The version may either be a minor
version or a patch version.
build45, build46 and build50
These are the scripts that respectively build Shorewall 4.5,
Shorewall 4.6 and Shorewall 5.0 packages from Git.
The scripts copy content from Git using the git
archive command. They then use that content to build the
packages. In addition to the usual Gnu utilities, the following software
is required:
rpmbuild
Required to build the RPM packages.
xsltproc (libxslt)
Required to convert the XML documents to other
formats.
Docbook XSL Stylesheets
Required to convert the XML documents to other
formats.
Perl
Required to massage some of the config files.
xmlto
Required to convert the XML manpages to manpages. Be sure
that you have a recent version; I use 0.0.25.
You should ensure that you have the latest scripts. The scripts
change periodically as we move through the release cycles.
The scripts may need to be modified to fit your particular
environment. There are a number of variables that are set near the top
of the file:
STYLESHEET
Must point to the XHTML docbook.xsl stylesheet from your
Docbook XSL Stylesheets installation.
LOGDIR
Directory where you want the build log placed. Defaults to
the current working directory.
RPMDIR
Points to your RPM directory .
DIR
Directory where you want the release to be built. Defaults
to the current working directory.
GIT
Shorewall GIT repository.
The scripts assume that there will be a separate build
directory per major release. Each build directory should
contain the empty file shorewall-pkg.config; that
file is no longer used but has been retained just as a guard against
initiating a build in an unintended directory. To build a release, you
cd to the appropriate directory and run the build script.
The general form of the build command is:
buildxx [ -options
] release [ prior
release ]
where
options
are one or more of the following. If no options are given
then all options are assumed
t
build tar files
r
build RPMs
c
Build the shorewall-core package.
i
Build the shorewall-init package.
l
Build the shorewall-lite package.
6
Build the shorewall6 package.
L
Build the shorewall6-lite package.
h
Build the html document package.
s
Build the shorewall package.
x
Build the xml document package.
release
The release version to build. Must match the version in the
associated Git path.
prior release
The release to be used to generate patch files.
Example 1 - Build Shorewall 4.5.7 and generate patches against
4.5.6:
build45 4.5.7 4.5.6
Example 2 - Build Shorewall 4.5.7.1 Shorewall-core and generate
patches against 4.5.7:
build45 -trc 4.5.7.1 4.5.7
upload
This script is used to upload a release to www.shorewall.org. The
command is run in the build directory for the minor release of the
product.
upload [ -products
] release
where
products
specifes the products to upload. If not given, all products
are uploaded. This option is generally given only when uploading a
patch release.
c
Upload the shorewall-core package.
l
Upload the shorewall-lite package.
i
Upload the shorewall-init package.
s
Upload the shorewall package.
6
Upload the shorewall6 package.
L
Upload the shorewall6-lite package.
release
The version number of the release to upload.
Example 1 - Upload release 4.3.7:
upload 4.3.7
Example 2 - Upload shorewall-core-4.3.7.3:
upload -c 4.3.7.3
install.sh files
Each product includes an install script
(install.sh) that may be used to install the
product on a machine or into a directory.
By default, the scripts install the corresponding product into
"/'; you can direct them to install into an empty existing directory by
setting an environmental variable:
DESTDIR (release 4.4.10 and later)
PREFIX (all releases)
There are a number of other environmental variables that you can
set to cause the directory to be populated for a particular target
environment:
DEBIAN - Debian-based systems (Debian, Ubuntu, etc.)
SUSE - SEL and OpenSuSE
REDHAT - RHEL, CentOS, Foobar, etc.
MAC - Apple MacIntosh (Shorewall-core, Shorewall and
Shorewall6 packages only)
CYGWIN - Cygwin under Windows (Shorewall-core, Shorewall and
Shorewall6 packages only)
OPENWRT - OpenWRT (Shorewall-core, Shorewall6-lite ad
Shorewall6-lite only)
