Build Prerequisites

debian-based

The list of debian packages dependencies can be installed with:

./install-deps.sh

Note: libsnappy-dev and libleveldb-dev are not available upstream for natty, oneiric, and squeeze. Backports for Ceph can be found at ceph.com/debian-leveldb.

rpm-based

The list of RPM packages dependencies can be installed with:

./install-deps.sh

Building Ceph

Developers, please refer to the Developer Guide for more information, otherwise, you can build the server daemons, and FUSE client, by executing the following:

./autogen.sh
./configure
make

(Note that the FUSE client will only be built if libfuse is present.)

Dependencies

The configure script will complain about any missing dependencies as it goes. You can also refer to debian/control or ceph.spec.in for the package build dependencies on those platforms. In many cases, dependencies can be avoided with --with-foo or --without-bar switches. For example,

./configure --with-nss         # use libnss instead of libcrypto++
./configure --without-radosgw  # do not build radosgw
./configure --without-tcmalloc # avoid google-perftools dependency

Building packages

You can build packages for Debian or Debian-derived (e.g., Ubuntu) systems with

sudo apt-get install dpkg-dev
dpkg-checkbuilddeps        # make sure we have all dependencies
dpkg-buildpackage

For RPM-based systems (Red Hat, SUSE, etc.),

rpmbuild

Building the Documentation

Prerequisites

The list of package dependencies for building the documentation can be found in doc_deps.deb.txt:

sudo apt-get install `cat doc_deps.deb.txt`

Building the Documentation

To build the documentation, ensure that you are in the top-level `/ceph directory, and execute the build script. For example:

admin/build-doc
