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.
