3. Quick Start

The following is a quick start guide that provides a basic set of commands to build the RTEMS Tools and Kernel. The quick start guide provides links to the detailed sections if any problems are encoutnered.

The detailed procedure for installing RTEMS can be found in Chapter 5 - Installation.

The development host computer needs to be set up for this quick start procedure to complete successfully. Chapter 4 - Host Computer details what is needed for the supported host operating systems. If Windows is being used it is recommended following the procedure in Chapter 4 Section 4 - Microsoft Windows first.

Their are many ways and locations a suitable environment can be set up. A common factor that defines the final location of tools and projects is the place you have suitable storage. Chapter 5 Section 1 - Prefixes and Chapter 5 Section 1.1 - Project Sandboxing provide detailed examples of possible locations and set ups .

This procedure installs a developer set up using the RTEMS Git repositories on a Unix (POSIX) or MacOS host. The output from the commands has been removed and replaced with ....

Create a workspace, download the RTEMS Source Builder (RSB) and build a tool chain (Chapter 5 Section 3.1 - POSIX and OS X Host Tools Chain):

$ cd
$ mkdir -p development/rtems
$ cd development/rtems
$ git clone git://git.rtems.org/rtems-source-builder.git rsb
  ...
$ cd rsb
$ ./source-builder/sb-check
  ...
$ cd rtems
$ ../source-builder/sb-set-builder \
    --prefix=/usr/home/chris/development/rtems/4.12 4.12/rtems-sparc
  ...

Build the RTEMS Kernel (Chapter 5 Section 3.2.2 - Building the Kernel) by cloning the repository, running the bootstrap procecure, building and finally installing the kernel:

$ export PATH=$HOME/development/rtems/4.12/bin:$PATH
$ cd
$ cd development/rtems
$ mkdir kernel
$ cd kernel
$ git clone git://git.rtems.org/rtems.git rtems
  ...
$ cd rtems
$ ./bootstrap -c && ./bootstrap -p && \
            $HOME/development/rtems/rsb/source-builder/sb-bootstrap
  ...
$ cd ..
$ mkdir erc32
$ cd erc32
$ $HOME/development/rtems/kernel/rtems/configure --prefix=$HOME/development/rtems/4.12 \
                   --target=sparc-rtems4.12 --enable-rtemsbsp=erc32 --enable-posix
  ...
$ make -j 8
  ...
$ make install

You can now build a 3rd party library or an application.
