Build Prerequisites


The list of debian packages dependencies can be installed with:


Note: libsnappy-dev and libleveldb-dev are not available upstream for Debian Squeeze. Backports for Ceph can be found at


The list of RPM packages dependencies can be installed with:


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:


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


The configure script will complain about any missing dependencies as it goes. You can also refer to debian/control or 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

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


Building the Documentation


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:
