Building Your Own Application
=============================
Compiling a Sample Application in the Development Kit Directory
---------------------------------------------------------------
To compile a sample application with make (for example, hello world):
.. code-block:: console
~/DPDK$ cd examples/helloworld/
~/DPDK/examples/helloworld$ make
The binary is generated in the build directory by default:
.. code-block:: console
~/DPDK/examples/helloworld$ ls build/app
helloworld helloworld.map
Please refer to :doc:`../linux_gsg/build_dpdk` for details on compiling with meson.
Build Your Own Application Outside the Development Kit
------------------------------------------------------
The sample application (Hello World) can be duplicated in a new directory as a starting point for your development:
.. code-block:: console
~$ cp -r DPDK/examples/helloworld my_rte_app
~$ cd my_rte_app/
~/my_rte_app$ make
Customizing Makefiles
---------------------
Application Makefile
~~~~~~~~~~~~~~~~~~~~
The default makefile provided with the Hello World sample application is a good starting point.
The user must define several variables:
* APP: Contains the name of the application.
* SRCS-y: List of source files (\*.c, \*.S).
