# 4.2. 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 Chapter 3 - 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 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.

## 4.2.1. 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, 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:

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 Chapter 3 Section 4 - 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. ### 4.2.2.1. RTEMS Windows Tools¶ Create a workspace for RTEMS using the following shell command:  ~$ 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:

### 4.2.2.2. 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
$git clone git://git.rtems.org/rtems.git rtems Cloning into 'rtems'... remote: Counting objects: 482766, done. remote: Compressing objects: 100% (88781/88781), done. remote: Total 482766 (delta 389610), reused 475155 (delta 383437) Receiving objects: 100% (482766/482766), 69.77 MiB | 697.00 KiB/s, done. Resolving deltas: 100% (389610/389610), done. Checking connectivity... done. Checking out files: 100% (10626/10626), done. /c/opt/rtems/kernel$ cd rtems
/c/opt/rtems/kernel/rtems
$git checkout 4.11 Checking out files: 100% (2553/2553), done. Branch 4.11 set up to track remote branch 4.11 from origin. Switched to a new branch '4.11' /c/opt/rtems/kernel$


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

/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:

 /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
