.. _QuickStartBootstrap:
|
|
|
|
Bootstrap the RTEMS Sources
|
|
===========================
|
|
|
|
You installed the tool suite in your installation prefix and cloned two RTEMS
|
|
repositories in the previous sections. We installed the tool suite in
|
|
:file:`$HOME/quick-start/rtems/5` and cloned the repositories in
|
|
:file:`$HOME/quick-start/src`.
|
|
|
|
If you use source archives of a released RTEMS version, then you can skip this
|
|
section.
|
|
|
|
Before you can build a :ref:`Board Support Package (BSP) <BSPs>` for your
|
|
target hardware, 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.

./bootstrap -c

These commands should output something like this (omitted lines are denoted by
