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

To get started developing with VPP you need to get the sources and build the packages.

.. _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 and get ready to build execute the following:

.. 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 these commands to install the dependencies for FD.io VPP. 
If it hangs during downloading at any point, you may need to set up :ref:`proxies for this to work <setupproxies>`.

.. code-block:: console

    $ make install-dep

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

This build version contains debug symbols which is useful to modify VPP. The command
below will build 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'

    @@@@ Installing vpp: nothing to do @@@@
    make[1]: Leaving 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.

.. code-block:: console

    $ make build-release


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

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

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

.. code-block:: console

    $ make pkg-deb 


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

.. 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
