   1             How to Build Debian Packages for Open vSwitch
   2             =============================================
   3
   4 This document describes how to build Debian packages for Open vSwitch.
   5 To install Open vSwitch on Debian without building Debian packages,
   6 see INSTALL instead.
   7
   8 These instructions should also work on Ubuntu and other Debian
   9 derivative distributions.
  10
  11
  12 Before You Begin
  13 ----------------
  14
  15 Before you begin, consider whether you really need to build packages
  16 yourself.  Debian "wheezy" and "sid", as well as recent versions of
  17 Ubuntu, contain pre-built Debian packages for Open vSwitch.  It is
  18 easier to install these than to build your own.  To use packages from
  19 your distribution, skip ahead to "Installing .deb Packages", below.

  21
  22 Building Open vSwitch Debian packages
  23 -------------------------------------
  24
  25 You may build from an Open vSwitch distribution tarball or from an
  26 Open vSwitch Git tree with these instructions.
  27
  28 You do not need to be the superuser to build the Debian packages.
  29
  30 1. Install the "build-essential" and "fakeroot" packages, e.g. with
  31    "apt-get install build-essential fakeroot".
  32
  33 2. Obtain and unpack an Open vSwitch source distribution and "cd" into
  34    its top level directory.
  35
  36 3. Install the build dependencies listed under "Build-Depends:" near
  37    the top of debian/rules.  You can install these any way you like,
  38    e.g. with "apt-get install".
  39
  40    Check your work by running "dpkg-checkbuilddeps".  If you've
  41    installed all the dependencies properly, dpkg-checkbuilddeps will
  42    exit without printing anything.  If you forgot to install some
  43    dependencies, it will tell you which ones.
  44
  45 4. Run:
  46
  47        fakeroot debian/rules binary
  48
  49    This will do a serial build that runs the unit tests.  If you
  50    prefer, you can run a faster parallel build, e.g.:
  51
  52        DEB_BUILD_OPTIONS='parallel=8' fakeroot debian/rules binary
  53
  54    If you are in a big hurry, you can even skip the unit tests:
  55
  56        DEB_BUILD_OPTIONS='parallel=8 nocheck' fakeroot debian/rules binary
  57
  58 5. The generated .deb files will be in the parent directory of the
  59    Open vSwitch source distribution.
  60
  61
  62 Installing .deb Packages
  63 ------------------------
  64
  65 These instructions apply to installing from Debian packages that you
  66 built yourself, as described in the previous section, or from packages
  67 provided by Debian or a Debian derivative distribution such as Ubuntu.
  68 In the former case, use a command such as "dpkg -i" to install the
  69 .deb files that you build, and in the latter case use a program such
  70 as "apt-get" or "aptitude" to download and install the provided
  71 packages.
  72
  73 You must be superuser to install Debian packages.
  74
  75 1. Start by installing the "openvswitch-switch" and
  76    "openvswitch-common" packages.  These packages include the core
  77    userspace components of the switch.
  78
  79 2. Install an Open vSwitch kernel module.  There are multiple ways to
  80    do this.  In order of increasing manual effort, these are:
  81
  82        * Use a Linux kernel 3.3 or later, which has an integrated Open
  83          vSwitch kernel module.
  84
  85          The upstream Linux kernel module lacks a few features that
  86          are in the third-party module.  For details, please see the
  87          FAQ, "What features are not available in the Open vSwitch
  88          kernel datapath that ships as part of the upstream Linux
  89          kernel?".
  90
  91        * Install the "openvswitch-datapath-dkms" Debian package that
  92          you built earlier.  This should automatically build and
  93          install the Open vSwitch kernel module for your running
  94          kernel.
  95
  96          This option requires that you have a compiler and toolchain
  97          installed on the machine where you run Open vSwitch, which
  98          may be unacceptable in some production server environments.
  99
 100        * Install the "openvswitch-datapath-source" Debian package, use
 101          "module-assistant" to build a Debian package of the Open
 102          vSwitch kernel module for your kernel, and then install that
 103          Debian package.
 104
 105          You can install the kernel module Debian packages that you
 106          build this way on the same machine where you built it or on
 107          another machine or machines, which means that you don't
 108          necessarily have to have any build infrastructure on the
 109          machines where you use the kernel module.
 110
 111          /usr/share/doc/openvswitch-datapath-source/README.Debian has
 112          details on the build process.
 113
 114        * Build and install the kernel module by hand.
 115
 116 Open vSwitch .deb packages not mentioned above are rarely useful.
 117 Please refer to their individual package descriptions to find out
 118 whether any of them are useful to you.
