63. Building Your Own Application
63.1. Compiling a Sample Application in the Development Kit Directory
To compile a sample application with make (for example, hello world):
~/DPDK$ cd examples/helloworld/ ~/DPDK/examples/helloworld$ make
The binary is generated in the build directory by default:
~/DPDK/examples/helloworld$ ls build/app helloworld helloworld.map
Please refer to Compiling the DPDK Target from Source for details on compiling with meson.
63.2. 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:
~$ cp -r DPDK/examples/helloworld my_rte_app ~$ cd my_rte_app/ ~/my_rte_app$ make
63.3. Customizing Makefiles
63.3.1. 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).
