Copyright (C) 2016 Chris Johns .. _developer: .. _development-version: .. _unstable: 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-host-tools-chain: .. _macos-host-tools-chain: POSIX and OS X Host Tools Chain ------------------------------- This procedure will build a SPARC tool chain.
