.. _l2_fwd_app_real_and_virtual:
Compiling the Application
-------------------------
-#. Go to the example directory:
+To compile the sample application see :doc:`compiling`.
- .. code-block:: console
-
- export RTE_SDK=/path/to/rte_sdk
- cd ${RTE_SDK}/examples/l2fwd
-
-#. Set the target (a default target is used if not specified). 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:
-
- .. code-block:: console
-
- make
+The application is located in the ``l2fwd`` sub-directory.
Running the Application
