.. note::

These 4 steps may be needed every time the Linux kernel is updated.
Before re-doing the 4 steps, you can try the following lighter steps:

Go in the folder where the ethercat project was cloned, from step 2 (Setup sources) do:

.. code-block:: console

cd ethercat
sudo rm /usr/bin/ethercat /etc/init.d/ethercat
./bootstrap

From Step 4 (Configure system)

.. code-block:: console

sudo ln -s /usr/local/etherlab/bin/ethercat /usr/bin/
sudo ln -s /usr/local/etherlab/etc/init.d/ethercat /etc/init.d/ethercat
