Installation ============ .. index:: Installation -XXX: Some notes about waf etc. +RTEMS is built from source on your host machine. Releases are available from +our :r:url:`ftp` and each release contains a Quick Start build guide. If you +are wanting to track changes to RTEMS as they happen or you want to make +changes to RTEMS to send back to the project on our :r:list:`devel` then you +can use the developer's version available in our :r:url:`git`. +RTEMS supports development on a wide vararity of hosts. There is no preferred +host operating system the project requires you use. This means you are able to +decide on a host operating system that is your passion, suites your needs, or +in some cases is decided for you by your employer. Our aim is to provide a +consistent user experience and on matching hardware the experience should feel +similar. + +The RTEMS core development team uses POSIX type operating systems, that is +Unix. The `Released Version`_ and `Development Version`_ sections assume +Unix. Microsoft Windows is documented in a separate section +:ref:`microsoft-windows-installation`.

The project encouages +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. + +.. sidebar:: *GDB and Python* + + RTEMS uses Python in GDB to aid debugging which means GDB needs to be built + with Python development libraries. Please check the RSB documentation and + install the packages specified for your host. Make sure a python development + package is included. + +The following procedure assumes you have installed and configured your host +operating. 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 to install a +development version of 4.12 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. + +This procedure will build a SPARC tool chain. + +RTEMS Tools Chain +~~~~~~~~~~~~~~~~~ + +Clone the RTEMS Source Builder (RSB) repository: + +.. code-block:: shell + + $ cd + $ mkdir -p development/rtems + $ cd development/rtems + $ git clone git://git.rtems.org/rtems-source-builder.git rsb + Cloning into 'rsb'... + remote: Counting objects: 5837, done. + remote: Compressing objects: 100% (2304/2304), done. + remote: Total 5837 (delta 4014), reused 5056 (delta 3494) + Receiving objects: 100% (5837/5837), 2.48 MiB | 292.00 KiB/s, done. + Resolving deltas: 100% (4014/4014), done. + Checking connectivity... done. + +.. sidebar:: *Downloading the source* + + You need an internet connection to download the source.

The RTEMS Project likes to have +bugs fixed against a ticket created on our :r:url:`devel`. Please raise a +ticket if you have a bug. Any changes that are made can be tracked against the +ticket. If you want to add a new a feature please post a message to +:r:list:`devel` describing what you would like to implement. The RTEMS +maintainer will help decide if the feature is in the best interest of the +project. Not everything is and the maintainers need to evalulate how much +effort it is to maintain the feature. Once accepted into the source tree it +becomes the responsibility of the maintainers to keep the feature updated and +working. + +Changes to the source tree are tracked using git. If you have not made changes +and enter the source tree and enter a git status command you will see nothing +has changed: + +.. code-block:: shell + + $ cd ../rtems + $ git status + On branch master + Your branch is up-to-date with 'origin/master'. + nothing to commit, working directory clean + +We will make a change to the source code. In this example I change the help +message to the RTEMS shell's ``halt`` command. Running the same git status +command reports: + +.. code-block:: shell + + $ git status + On branch master + Your branch is up-to-date with 'origin/master'. + Changes not staged for commit: + (use "git add <file>..." to update what will be committed) + (use "git checkout -- <file>..." to discard changes in working directory) + + modified: cpukit/libmisc/shell/main_halt.c + + no changes added to commit (use "git add" and/or "git commit -a") + +As an example I have a ticket open and the ticket number is 9876.
