   2  Build Ceph
   3 ============
   4
   5 You can get Ceph software by retrieving Ceph source code and building it yourself.
   6 To build Ceph, you need to set up a development environment, compile Ceph,
   7 and then either install in user space or build packages and install the packages.
   8
   9 Build Prerequisites
  10 ===================
  11
  12
  13 .. tip:: Check this section to see if there are specific prerequisites for your
  14    Linux/Unix distribution.
  15
  16 Before you can build Ceph source code, you need to install several libraries
  17 and tools::
  18
  19         ./install-deps.sh
  20
  21 .. note:: Some distributions that support Google's memory profiler tool may use
  22    a different package name (e.g., ``libgoogle-perftools4``).
  23
  24 Build Ceph
  25 ==========
  26
  27 Ceph is built using cmake. To build Ceph, navigate to your cloned Ceph
  28 repository and execute the following::
  29
  30     cd ceph
  31     ./do_cmake.sh
  32     cd build
  33     make
  34
  35 .. topic:: Hyperthreading
  36
  37         You can use ``make -j`` to execute multiple jobs depending upon your system. For
  38         example, ``make -j4`` for a dual core processor may build faster.
  39
  40 See `Installing a Build`_ to install a build in user space.
  41
  42 Build Ceph Packages
  43 ===================
  44
  45 To build packages, you must clone the `Ceph`_ repository. You can create
  46 installation packages from the latest code using ``dpkg-buildpackage`` for
  47 Debian/Ubuntu or ``rpmbuild`` for the RPM Package Manager.
  48
  49 .. tip:: When building on a multi-core CPU, use the ``-j`` and the number of
  50    cores * 2. For example, use ``-j4`` for a dual-core processor to accelerate
  51    the build.
  52
  53
  54 Advanced Package Tool (APT)
  55 ---------------------------
  56
  57 To create ``.deb`` packages for Debian/Ubuntu, ensure that you have cloned the
  58 `Ceph`_ repository, installed the `Build Prerequisites`_ and installed
  59 ``debhelper``::
  60
  61         sudo apt-get install debhelper
  62
  63 Once you have installed debhelper, you can build the packages::
  64
  65         sudo dpkg-buildpackage
  66
  67 For multi-processor CPUs use the ``-j`` option to accelerate the build.
  68
  69
  70 RPM Package Manager
  71 -------------------
  72
  73 To create ``.rpm`` packages, ensure that you have cloned the `Ceph`_ repository,
  74 installed the `Build Prerequisites`_ and installed ``rpm-build`` and
  75 ``rpmdevtools``::
  76
  77         yum install rpm-build rpmdevtools
  78
  79 Once you have installed the tools, setup an RPM compilation environment::
  80
  81         rpmdev-setuptree
  82
  83 Fetch the source tarball for the RPM compilation environment::
  84
  85         wget -P ~/rpmbuild/SOURCES/ http://ceph.com/download/ceph-<version>.tar.bz2
  86
  87 Or from the EU mirror::
  88
  89         wget -P ~/rpmbuild/SOURCES/ http://eu.ceph.com/download/ceph-<version>.tar.bz2
  90
  91 Extract the specfile::
  92
  93     tar --strip-components=1 -C ~/rpmbuild/SPECS/ --no-anchored -xvjf ~/rpmbuild/SOURCES/ceph-<version>.tar.bz2 "ceph.spec"
  94
  95 Build the RPM packages::
  96
  97         rpmbuild -ba ~/rpmbuild/SPECS/ceph.spec
  98
  99 For multi-processor CPUs use the ``-j`` option to accelerate the build.
