Compiling the Hello World Pipeline

The name of the Hello World reference pipeline in the SSDK deliverable is hello_world. This is used as a CLI command.

To compile the pipeline, execute the following command:

# ARCH=x86_64 ./tools/build.sh --p4_program hello_world

Note: Compiling takes a few minutes to complete. To ensure that you compile the pipeline from a clean environment, run the following command:

# ARCH=x86_64 ./tools/build.sh --p4_program hello_world --clean

To start and run the hello world pipeline in the simulator, execute the following command:

# ./tools/dsc-sim-start.sh --p4_program hello_world

The following is an example of a successful start of the simulator.
