=============================
Building packages from source
=============================
Building RPMs
=============
Building from a tarball
-----------------------
* Create a directory structure for rpmbuild::
rpmdev-setuptree
* Copy the tarball to ``~/rpmbuild/SOURCES/``
* Extract another copy of it somewhere else (eg: ``/tmp``) and retrieve
the ``misc/bcfg2.spec`` file
* Run the following::
rpmbuild -ba bcfg2.spec
* The resulting RPMs will be in ``~/rpmbuild/RPMS/`` and SRPMs
in ``~/rpmbuild/SRPMS/``.
Building Debian packages
========================
The Bcfg2 project provides a ``debian`` subdirectory with the project's
source that enables users to create their own Debian/Ubuntu compatible
packages (`.deb` files).
Build deps
----------
If the distribution you are building on already has packaged bcfg2
(even an older version), the following command will likely install the
necessary build dependencies::
apt-get build-dep bcfg2 bcfg2-server
Install source code
-------------------
Depending on which version of bcfg2 you want build, you can obtain the
source code from the Download_ page or from the project's git repository.
To create a local anonymous working copy of the latest version of the
bcfg2 source code, use a command like the following::
git clone git://git.mcs.anl.gov/bcfg2.git
Update the changelog
--------------------
The next step is to update the ``debian/changelog`` file with an
appropriate package version string. Debian packages contain a version
that is extracted from the latest entry in this file. An appropriate
version will help you distinguish your locally built package from one
provided by your distribution. It also helps the packaging system know
when a newer version of the package is available to install.
It is possible to skip this step, but the packages you build will have
the same version as the source distribution and will be easy to confuse
with other similarly named (but maybe not equivalent) packages.
The basic format of the package version string to use is this::
<UPSTREAM VER>~<UPSTREAM PRE-VER>+<GIT-ID>-0.1+<LOCAL VER>
.. note::
The '+', and '-' characters have significance in determining when
one package is newer than another. The following format is believed
to do the right thing in all common situations.
The components of the package version string are explained below:
.. glossary::
<UPSTREAM VER>
This is the version of the Bcfg source code you are working
from. It will likely be something like `0.9.6` or `1.0`.
<UPSTREAM PRE-VER>
If you are using a published pre-release of Bcfg2, it will have
a name like `pre1` or `rc1`. Use that string here, otherwise
drop this component from the package version string.
+<GIT-ID>
If you are building from a local working copy of the git
repository, it is useful to include the revision in the package
version. If you are building from a downloaded copy of the source,
drop this component (including the preceding plus-sign (`+`)
from the package version string.
+<LOCAL VER>
This is a locally relevant name like your last name or your
domain name, plus the digit `1`. For example, if your family
name is ''Smith'', you could use `smith1`. If you work for
''Example Inc'', you could use `example1`.
Here are some examples:
* If you are building packages for revision 6c681bd from git, and the
latest published version is 1.2.0rc1, the version string should be
`1.2.0rc1+6c681bd-0.1+example1`.
* If you are building packages for the published 1.0 rc1 version, the
version string should be `1.0rc1-0.1+example1`.
* If you are building packages for the published 1.0 version, the version
string should be `1.0-0.1+example1`.
If you are working on a git working copy of 1.0 pre5 and have the
``devscripts`` package installed, the following command is a convenient
way to create a well formatted changelog entry::
REV=$(git log --oneline | head -n 1 | cut -d' ' -f1)
debchange --force-bad-version --preserve --newversion "1.0~pre5+${REV}-0.1+example1" git revision $REV
Building the package
--------------------
With the preliminaries out of the way, building the package is simple.::
cd .. # Change into the top level of the source directory
fakeroot dpkg-buildpackage -uc -us
The freshly built packages will be deposited in the parent of the
current directory (``..``). Examine the output of ``dpkg-buildpackage``
for details.
External build systems
----------------------
This section describes how to build bcfg2 and deps via external build
systems (Currently only a PPA). Some other possibilities are:
* #651 Look into project-builder to make more native-system bcfg2 packages available
* http://en.opensuse.org/Build_Service/Deb_builds
Launchpad PPA
^^^^^^^^^^^^^
https://launchpad.net/~bcfg2
To upload to the PPA you need to be on the active member list of `Bcfg2
in Launchpad`_.
Note that **after each successful upload**, you should wait until the PPA
is built, and then **install it locally** using ``sudo aptitude update;
sudo aptitude install (packagename)`` so the next build doesn't fail on
your local machine. If you don't want to wait for a PPA binary build to
complete, you can "apt-get source (packagename)" and do a local build
before the PPA build is done.
setup gpg-agent
"""""""""""""""
Setting up gpg-agent and pinentry prevents you from having to type your
passphrase repeatedly.::
sudo aptitude install gnupg-agent pinentry-gtk2 pinentry-curses
# replace 0xAA95C349 with your GPG Key ID
export GPGKEY=0xAA95C349
killall -q gpg-agent
eval $(gpg-agent --daemon)
setup debuild
"""""""""""""
Tell dpkg-buildpackage who you are, for example::
export DEBEMAIL="dclark@pobox.com"
export DEBFULLNAME="Daniel Joseph Barnhart Clark"
upload bcfg2 to ppa
"""""""""""""""""""
A ``dists`` file contains a space-separated list of all distributions
you want to build PPA packages for.
.. code-block:: sh
#!/bin/sh
. ./dists
# Replace 0xAA95C349 with your GnuPG Key ID
export GPGKEY=0xAA95C349
sudo apt-get build-dep bcfg2 bcfg2-server
sudo aptitude install git
