Compiling the Sample Applications
|
|
=================================
|
|
|
|
This section explains how to compile the DPDK sample applications.
|
|
|
|
To compile all the sample applications
|
|
--------------------------------------
|
|
|
|
|
|
Set the path to DPDK source code if its not set:
|
|
|
|
.. code-block:: console
|
|
|
|
export RTE_SDK=/path/to/rte_sdk
|
|
|
|
Go to DPDK source:
|
|
|
|
.. code-block:: console
|
|
|
|
cd $RTE_SDK
|
|
|
|
Build DPDK:
|
|
|
|
.. code-block:: console
|
|
|
|
make defconfig
|
|
make
|
|
|
|
Build the sample applications:
|
|
|
|
.. code-block:: console
|
|
|
|
export RTE_TARGET=build
|
|
make -C examples
|
|
|
|
For other possible ``RTE_TARGET`` values and additional information on
|
|
compiling see
|
|
:ref:`Compiling DPDK on Linux <linux_gsg_compiling_dpdk>` or
|
|
:ref:`Compiling DPDK on FreeBSD <building_from_source>`.
|
|
Applications are output to: ``$RTE_SDK/examples/app-dir/build`` or
|
|
``$RTE_SDK/examples/app-dir/$RTE_TARGET``.
|
|
|
|
|
|
In the example above the compiled application is written to the ``build`` subdirectory.
|
|
To have the applications written to a different location,
|
|
the ``O=/path/to/build/directory`` option may be specified in the make command.
|
|
|
|
.. code-block:: console
|
|
|
|
make O=/tmp
|
|
|
|
To build the applications for debugging use the ``DEBUG`` option.
|
|
This option adds some extra flags, disables compiler optimizations and
|
|
sets verbose output.
|
|
|
|
.. code-block:: console
|
|
|
|
make DEBUG=1
|
|
|
|
|
|
To compile a single application
|
|
-------------------------------
|
|
|
|
Set the path to DPDK source code:
|
|
|
|
.. code-block:: console
|
|
|
|
export RTE_SDK=/path/to/rte_sdk
|
|
|
|
Go to DPDK source:
|
|
|
|
.. code-block:: console
|
|
|
|
cd $RTE_SDK
|
|
|
|
Build DPDK:
|
|
|
|
.. code-block:: console
|
|
|
|
make defconfig
|
|
make
|
|
|
|
Go to the sample application directory. Unless otherwise specified the sample
|
|
applications are located in ``$RTE_SDK/examples/``.
|
|
|
|
|
|
Build the application:
|
|
|
|
.. code-block:: console
|
|
|
|
export RTE_TARGET=build
|
|
make
|
