Compiling the Application
-------------------------
-To compile the application export the path to the DPDK source tree and go to
-the example directory:
-
-.. code-block:: console
-
- export RTE_SDK=/path/to/rte_sdk
-
- cd ${RTE_SDK}/examples/flow_filtering
-
-Set the target, for example:
-
-.. code-block:: console
-
- export RTE_TARGET=x86_64-native-linuxapp-gcc
-
-See the *DPDK Getting Started* Guide for possible ``RTE_TARGET`` values.
-
-Build the application as follows:
-
-.. code-block:: console
-
- make
+To compile the sample application see :doc:`compiling`.
Running the Application
-----------------------
-To run the example in a ``linuxapp`` environment:
+To run the example in a ``linux`` environment:
.. code-block:: console
- ./build/flow -l 1 -n 1
+ ./<build_dir>/examples/dpdk-flow_filtering -l 1 -n 1
Refer to *DPDK Getting Started Guide* for general information on running
applications and the Environment Abstraction Layer (EAL) options.
