Development Version
|
|
===================
|
|
.. index:: Git
|
|
|
|
RTEMS provides open access to it's development processes. 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.
|
|
|
|
Please read :ref:`development-hosts` before continuing.
|
|
|
|
.. warning::
|
|
|
|
The development version is not for use in production and it can break from
|
|
time to time.
|
|
|
|
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.

$ mkdir -p development/rtems
|
|
$ cd development/rtems

|
|
.. 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`.
|
|
|
|
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:: shell
|
|
|
|
$ cd rsb
|
|
$ ./source-builder/sb-check

Environment is ok

Build a tool chain for the SPARC architecure. 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 `4.12` and is on master:

RTEMS Kernel
|
|
------------
|
|
|
|
We need to set our path to include the RTEMS tools we built in the previous
|
|
section. The RTEMS tools needs to be first in your path because RTEMS provides
|
|
specific versions of the ``autoconf`` and ``automake`` tools. We want to use
|
|
the RTEMS version and not your host's versions:
|
|
|
|
|
|
.. code-block:: shell
|
|
|
|
$ export PATH=$HOME/development/rtems/4.12/bin:$PATH
|
|
|
|
Create a new location to build the RTEMS kernel:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ cd
|
|
$ cd development/rtems
|
|
$ mkdir kernel
|
|
$ cd kernel
|
|
|
|
Clone the RTEMS respository:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ git clone git://git.rtems.org/rtems.git rtems
|

|
|
|
The developers version of the code from git requires we ``bootstrap`` the
|
|
source code. This is an ``autoconf`` and ``automake`` bootstrap to create the
|
|
various files generated by ``autoconf`` and ``automake``. RTEMS does not keep
|
|
these generated files under version control. The bootstrap process is slow so
|
|
to speed it up the RSB provides a command that can perform the bootstrap in
|
|
parallel using your available cores. We need to enter the cloned source
|
|
directory then run the bootsrap commands:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ cd rtems
|
|
$ ./bootstrap -c && ./bootstrap -p && \
|
|

Bootstrap time: 0:02:47.398824
|
|
|
|
We build RTEMS in a directory outside of the source tree we have just cloned
|
|
and ``bootstrapped``. You cannot build RTEMS while in the source tree. Lets
|
|
create a suitable directory using the name of the BSP we are going to build:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ cd ..
|
|
$ mkdir erc32
|
|
$ cd erc32
|
|
|
|
Configure RTEMS using the ``configure`` command. We use a full path to
|
|
``configure`` so the object files built contain the absolute path of the source
|
|
files. If you are source level debugging you will be able to access the source
|
|
code to RTEMS from the debugger. We will build for the ``erc32`` BSP with POSIX
|
|
enabled and the networking stack disabled:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ $HOME/development/rtems/kernel/rtems/configure --prefix=$HOME/development/rtems/4.12 \
|
|
--target=sparc-rtems4.12 --enable-rtemsbsp=erc32 --enable-posix \
|

All that remains to be done is to install the kernel. Installing RTEMS copies
|
|
the API headers and architecture specific libraries to a locaiton under the
|
|
`prefix` you provide. You can install any number of BSPs under the same
|
|
`prefix`. We recommend you have a separate `prefix` for different versions of
|
|
RTEMS. Do not mix versions of RTEMS under the same `prefix`. Make installs
|
|
RTEMS with the following command:

Contributing Patches
|
|
--------------------
|
|
|
|
RTEMS welcomes fixes to bugs and new features. 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. I commit the
|
|
change with the follow git command:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ git commit cpukit/libmisc/shell/main_halt.c
|
|
|
|
An editor is opened and I enter my commit message. The first line is a title
|
|
and the following lines form a body. My message is:
|
|
|
|
.. code-block:: shell
|
|
|
|
shell: Add more help detail to the halt command.
|
|
|
|
Closes #9876.
|
|
|
|
# Please enter the commit message for your changes. Lines starting
|
|
# with '#' will be ignored, and an empty message aborts the commit.
|
|
# Explicit paths specified without -i or -o; assuming --only paths...
|
|
#
|
|
# Committer: Chris Johns <chrisj@rtems.org>
|
|
#

# On branch master
|
|
# Your branch is up-to-date with 'origin/master'.
|
|
#
|
|
# Changes to be committed:
|
|
# modified: cpukit/libmisc/shell/main_halt.c
|
|
|
|
When you save and exit the editor git will report the commit's status:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ git commit cpukit/libmisc/shell/main_halt.c
|
|
[master 9f44dc9] shell: Add more help detail to the halt command.
|
|
1 file changed, 1 insertion(+), 1 deletion(-)
|
|
|
|
You can either email the patch to :r:list:`devel` with the following git
|
|
command:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ git send-email --to=devel@rtems.org -1
|
|
<add output here>
|
|
|
|
Or you can ask git to create a patch file using:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ git format-patch -1
|
|
0001-shell-Add-more-help-detail-to-the-halt-command.patch
|
|
|
|
This patch can be attached to a ticket.
