.. _QuickStartBootstrap:
Bootstrap the RTEMS Sources
===========================
You installed the tool suite in your installation prefix and made ready the
source for two RTEMS source packages in the previous sections. We installed
the tool suite in :file:`$HOME/quick-start/rtems/5` and unpacked the RSB source
in :file:`$HOME/quick-start/src`.
You only need to *bootstrap* the RTEMS sources if you have used
:ref:`QuickStartSources_Git` to get the sources. If you use source archives of
a released RTEMS version you can skip this section and move to
:ref:`QuickStartBSPBuild`.
Before you can build a :ref:`Board Support Package (BSP) <BSPs>` for your
target hardware from Git cloned RTEMS sources, you have to bootstrap the build
system in the RTEMS sources. This is only necessary if you use a Git
repository clone of the RTEMS sources. You have to do this after a fresh
repository clone and sometimes after build system file updates (e.g. after a
``git pull``). If you are not a build system expert, then do the bootstrap
after each update of build system files. This is a bit annoying, but improving
the build system is a complex and time consuming undertaking. Feel free to
help the RTEMS Project to improve it. For the bootstrap it is important that
the right version of Autotools (:file:`autoconf` and :file:`automake`) are in
your ``$PATH``. The right version of Autotools is shipped with the RTEMS tool
suite you already installed. Set the path to the tool suite installed under
your selected *prefix*:
.. code-block:: none
export PATH=$HOME/quick-start/rtems/5/bin:"$PATH"
Change into the RTEMS source tree to *bootstrap* the build system:
.. code-block:: none
cd $HOME/quick-start/src/rtems
./rtems-bootstrap
This command should output something like this (omitted lines are denoted by
``...``):
.. code-block:: none
