Building VPP
============

To get started developing with VPP you need to get the sources and build the packages.
For more information on the build system please refer to :ref:`buildsystem`.

.. _setupproxies:

Set up Proxies
--------------------------

Depending on the environment, proxies may need to be set. 
You may run these commands:

.. code-block:: console

    $ export http_proxy=http://<proxy-server-name>.com:<port-number>
    $ export https_proxy=https://<proxy-server-name>.com:<port-number>


Get the VPP Sources
-----------------------------------

To get the VPP sources that are used to create the build, run the following commands:

.. code-block:: console

    $ git clone https://gerrit.fd.io/r/vpp
    $ cd vpp

Build VPP Dependencies
--------------------------------------

Before building, make sure there are no FD.io VPP or DPDK packages installed by entering the following
commands:

.. code-block:: console

    $ dpkg -l | grep vpp 
    $ dpkg -l | grep DPDK

There should be no output, or packages showing after each of the above commands.

Run the following **make** command to install the dependencies for FD.io VPP. 
If it hangs at any point during the download, then you may need to set up
:ref:`proxies for this to work <setupproxies>`.

.. code-block:: console

Build VPP (Debug)
----------------------------

This build version contains debug symbols which are useful for modifying VPP. The
**make** command below builds a debug version of VPP. The binaries, when building the
debug images, can be found in /build-root/vpp_debug-native.

.. code-block:: console

    $ make build
    make[1]: Entering directory '/home/vagrant/vpp-master/build-root'

Build VPP (Release Version)
-----------------------------------------

To build the release version of FD.io VPP. This build is optimized and will not create debug symbols.
The binaries when building the release images can be found in /build-root/vpp-native.

Use the following **make** command below to build the release version of FD.io VPP. This build is
optimized and will not create debug symbols. When building the release images, the binaries can
be found in /build-root/vpp-native.

.. code-block:: console

    $ make build-release


Building Necessary Packages
--------------------------------------------

Building Debian Packages
^^^^^^^^^^^^^^^^^^^^^^^^^

To build the debian packages, use one of the following commands below, depending on the system:

.. code-block:: console

    $ make pkg-deb 

Building RPM Packages
^^^^^^^^^^^^^^^^^^^^^^^

To build the rpm packages, use one of the following commands below, depending on the system:

.. code-block:: console

    $ make pkg-rpm

Once the packages are builty they can be found in the build-root directory.

.. code-block:: console
    
    $ ls *.deb

    If packages built correctly, this should be the Output

    vpp_18.07-rc0~456-gb361076_amd64.deb             vpp-dbg_18.07-rc0~456-gb361076_amd64.deb
    vpp-api-java_18.07-rc0~456-gb361076_amd64.deb    vpp-dev_18.07-rc0~456-gb361076_amd64.deb
    vpp-api-lua_18.07-rc0~456-gb361076_amd64.deb     vpp-lib_18.07-rc0~456-gb361076_amd64.deb
    vpp-api-python_18.07-rc0~456-gb361076_amd64.deb  vpp-plugins_18.07-rc0~456-gb361076_amd64.deb

Finally, the packages can be installed with the following:

For Ubuntu:

.. code-block:: console

   $ sudo bash
   # dpkg -i *.deb

For Centos or Redhat:

.. code-block:: console

   $ sudo bash
   # rpm -ivh *.rpm
