5.2. Developer (Unstable)

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 Host Computer 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 development/rtems. Using a home directory means you can do this without needing to be root. You can also use /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 5 in production it is not a good idea to install a development version of 6 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.

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.

5.2.1. POSIX and OS X Host Tools Chain

This procedure will build a SPARC tool chain.

Clone the RTEMS Source Builder (RSB) repository:

$ 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:

$ cd rsb
$ ./source-builder/sb-check
RTEMS Source Builder - Check, 6 (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:

1. Only option required is --list-bsets

2. The paths inspected. See Configuration.

3. A build set to build all RTEMS 6 supported architectures.

4. The build set for the ARM architecture on RTEMS 6.

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 development version is one more than 6` and is on the ``master branch:

5.2.2. Windows Host Tool Chain

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 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.

5.2.2.1. RTEMS Windows Tools

Create a workspace for RTEMS using the following shell command:

Creating Tool Archives

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

 ~
$ 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:

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

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

 /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:

 /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:

 /c/opt/rtems/rsb/rtems

5.2.2.2. 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:

 /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:

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

Branch 4.11 set up to track remote branch 4.11 from origin.
Switched to a new branch '4.11'
 /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:

 /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:

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

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:

 /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:

 /c/opt/rtems/kernel/pc686
$ /c/opt/rtems/kernel/rtems/configure --prefix=/c/opt/rtems/4.11 \

target architecture: i386.
available BSPs: pc686.
'make all' will build the following BSPs: pc686.
other BSPs can be built with 'make RTEMS_BSP="bsp1 bsp2 ..."'
