Developer (Unstable)
====================
.. index:: Git

RTEMS provides open access to it's development processes. We call this the
developer set up.  The project encourages all users to inspect, review, comment
and contribute to the code base. The processes described here are the same
processes the core development team use when developing and maintaining RTEMS.

.. warning::

   The development version is not for use in production and it can break from
   time to time.

Please read :ref:`development-host` before continuing. The following procedure
assumes you have installed and configured your host operating system. It also
assumes you have installed any dependent packages needed when building the
tools and the kernel.

You need to select a location to build and install the RTEMS Tool chain and
RTEMS. Make sure there is plenty of disk space and a fast disk is
recommended. Our procedure will document building and installing the tools in a
home directory called :file:`development/rtems`. Using a home directory means
you can do this without needing to be root. You can also use
:file:`/opt/rtems/build` if you have access to that path.

The location used to install the tools and kernel is called the `prefix`. It is
best to have a `prefix` for each different version of RTEMS you are using. If
you are using RTEMS 4.11 in production it is not a good idea to install a
development version of 5 over the top. A separate `prefix` for each version
avoids this.

The RTEMS tool chain changes less often than the RTEMS kernel. One method of
working with development releases is to have a separate `prefix` for the RTEMS
tools and a different one for the RTEMS kernel. You can then update each
without interacting with the other. You can also have a number of RTEMS
versions available to test with.

.. sidebar:: *Downloading the source*

  You need an internet connection to download the source. The downloaded source
  is cached locally and the RSB checksums it. If you run a build again the
  download output will be missing. Using the RSB from git will download the
  source from the upstream project's home site and this could be `http`, `ftp`,
  or `git`.

POSIX and OS X Host Tools Chain
-------------------------------

This procedure will build a SPARC tool chain.

Clone the RTEMS Source Builder (RSB) repository:

.. code-block:: none

  $ cd
  $ mkdir -p development/rtems
  $ cd development/rtems
  $ git clone git://git.rtems.org/rtems-source-builder.git rsb

Check all the host packages you need are present. Current libraries are not
checked and this includes checking for the python development libraries GDB
requires:

.. code-block:: none

  $ cd rsb
  $ ./source-builder/sb-check
  RTEMS Source Builder - Check, 5 (089327b5dcf9)
  Environment is ok

If you are unsure how to specify the build set for the architecture you wish to
build, just ask the tool:

  5. Support build set file with common functionality included by other build
     set files.

Build a tool chain for the SPARC architecture. We are using the SPARC
architecture because GDB has a good simulator that lets us run and test the
samples RTEMS builds by default. The current development version
is `5` and is on master:

Windows Host Tool Chain
-----------------------
.. index:: Microsoft Windows Installation

This section details how you create an RTEMS development environment on
Windows. The installation documented here is on `Windows 7 64bit
Professional`. Building on `Windows 10` has been reported as working.

Please see :ref:`microsoft-windows` before continuing.

.. note::

   If the RSB reports ``error: no hosts defaults found; please add`` you have
   probably opened an MSYS2 32bit Shell. Close all 32bit Shell windows and open
   the MSYS2 64bit Shell.

RTEMS Windows Tools
^^^^^^^^^^^^^^^^^^^

Create a workspace for RTEMS using the following shell command:

.. sidebar:: *Creating Tool Archives*

  Add ``--bset-tar-file`` to the ``sb-set-builder`` command line to create
  tar files of the built package set.

.. code-block:: none

   ~
  $ mkdir -p /c/opt/rtems

The ``/c`` path is an internal MSYS2 mount point of the ``C:`` drive. The
command creates the RTEMS work space on the ``C:`` drive. If you wish to use
another drive please subsitute ``/c`` with your drive letter.

We build and install all RTEMS packages under the `prefix` we just
created. Change to that directory and get a copy of the RSB:

.. code-block:: none

   ~
  $ cd /c/opt/rtems
   /c/opt/rtems
  $ git clone git://git.rtems.org/rtems-source-builder.git rsb

   /c/opt/rtems
  $ cd rsb

We are building RTEMS 4.11 tools so select the *4.11* branch:

.. code-block:: none

   /c/opt/rtems/rsb
  $ git checkout 4.11
  Branch 4.11 set up to track remote branch 4.11 from origin.
  Switched to a new branch '4.11'
   /c/opt/rtems/rsb
  $

Check the RSB has a valid environment:

.. code-block:: none

   /c/opt/rtems/rsb
  $ cd rtems
   /c/opt/rtems/rsb/rtems
  $ ../source-builder/sb-check
  RTEMS Source Builder - Check, 4.11 (01ac76f2f90f)
  Environment is ok
   /c/opt/rtems/rsb/rtems
  $

To build a set of RTEMS tools for the Intel ``i386`` architecture. The build
runs a single job rather than a job per CPU in your machine and will take a
long time so please be patient. The RSB creates a log file containing all the
build output and it will be changing size. The RSB command to build ``i386``
tools is:

Building the Kernel
^^^^^^^^^^^^^^^^^^^

We can now build the RTEMS kernel using the RTEMS tools we have just
built. First we need to set the path to the tools:

.. code-block:: none

   /c
  $ cd /c/opt/rtems
   /c/opt/rtems
  $ export PATH=/c/opt/rtems/4.11/bin:$PATH
   /c/opt/rtems
  $

We currently build RTEMS from the git release branch for 4.11:

.. code-block:: none

   /c/opt/rtems
  $ mkdir kernel
   /c/opt/rtems
  $ cd kernel
   /c/opt/rtems/kernel
  $ git clone git://git.rtems.org/rtems.git rtems

   /c/opt/rtems/kernel
  $

The kernel code cloned from git needs to be `bootstrapped`. Bootstrapping
creates ``autoconf`` and ``automake`` generated files. To bootstrap we first
clean away any files, then generate the pre-install header file lists and
finally we generate the ``autoconf`` and ``automake`` files using the RSB's
bootstrap tool. First we clean any generated files that exist:

.. code-block:: none

   /c/opt/rtems/kernel/rtems
  $ ./bootstrap -c
  removing automake generated Makefile.in files
  removing configure files
  removing aclocal.m4 files

Then we generate the pre-install header file automake make files:

.. code-block:: none

   /c/opt/rtems/kernel/rtems
  $ ./bootstrap -p
  Generating ./c/src/ada/preinstall.am
  Generating ./c/src/lib/libbsp/arm/altera-cyclone-v/preinstall.am

  Generating ./cpukit/wrapup/preinstall.am

   /c/opt/rtems/kernel/rtems

Finally we run the RSB's parallel ``bootstrap`` command:

We will build the RTEMS kernel for the ``i386`` target and the ``pc686``
BSP. You can check the available BSPs by running the ``rtems-bsps`` command
found in the top directory of the RTEMS kernel source. We build the Board
Support Package (BSP) outside the kernel source tree:

.. code-block:: none

   /c/opt/rtems/kernel/rtems
  $ cd ..
   /c/opt/rtems/kernel
  $ mkdir pc686
   /c/opt/rtems/kernel
  $ cd pc686
   /c/opt/rtems/kernel/pc686
  $

Configure the RTEMS kernel to build ``pc686`` BSP for the ``i386`` target with
networking disabled, We will build the external libBSD stack later:
