===================
Build Ceph Packages
===================

To build packages, you must clone the `Ceph`_ repository.
You can create installation packages from the latest code using ``dpkg-buildpackage`` for Debian/Ubuntu
or ``rpmbuild`` for the RPM Package Manager.

.. tip:: When building on a multi-core CPU, use the ``-j`` and the number of cores * 2.
   For example, use ``-j4`` for a dual-core processor to accelerate the build.


Advanced Package Tool (APT)
---------------------------

To create ``.deb`` packages for Debian/Ubuntu, ensure that you have cloned the `Ceph`_ repository,
installed the `build prerequisites`_ and installed ``debhelper``::

	$ sudo apt-get install debhelper

Once you have installed debhelper, you can build the packages:

	$ sudo dpkg-buildpackage

For multi-processor CPUs use the ``-j`` option to accelerate the build.

RPM Package Manager
-------------------

To create ``.prm`` packages, ensure that you have cloned the `Ceph`_ repository,
installed the `build prerequisites`_ and installed ``rpm-build`` and ``rpmdevtools``::

	$ yum install rpm-build rpmdevtools

Once you have installed the tools, setup an RPM compilation environment::

	$ rpmdev-setuptree

Fetch the source tarball for the RPM compilation environment::

	$ wget -P ~/rpmbuild/SOURCES/ http://ceph.newdream.net/download/ceph-<version>.tar.gz

Build the RPM packages::

	$ rpmbuild -tb ~/rpmbuild/SOURCES/ceph-<version>.tar.gz

For multi-processor CPUs use the ``-j`` option to accelerate the build.
