'''Status:'''  
 [http://google-summer-of-code-2008-rtems.googlecode.com/files/RyanJames_Harrison.tar.gz Packaging] generated as a GSOC 2008 project.  Ralf Corsépius wrote an [http://git.rtems.org/rtems-buildsys/tree/rtems-sbuild sbuild] application for generating Debian hosted RTEMS tools. Need to verify with Ralf Corsépius before proceeding to use as a GSoC project.

Pre-compiled versions of the RTEMS tools are currently available for RPM-based GNU/Linux distributions such as Fedora, RedHat Enterprise
Linux, CentOS, and SUSE as well as MS-Windows via MinGW.  This project consists of the development of comparable .deb package specifications and build scripts.  The resulting packaging and infrastructure should be suitable for at least GNU/Debian and Ubuntu distributions.  As the RTEMS toolset updates frequently, there must be scripting infrastructure developed to build these tools easily when updates are required.

[wiki:RalfCorsepius RalfCorsepius] is the RPM builder and maintainer.  He uses [http://fedoraproject.org/wiki/Projects/Mock Mock] to use a single development machine to build binaries for a variety
of distributions.  He is a good resource or mentor for this project.

The Debian alternative to Mock is: [https://wiki.ubuntu.com/PbuilderHowto Pbuilder]. Pbuilder apparently has been packaged for [http://pkgs.org/fedora-16/rpm-sphere-i586/pbuilder-0.211-11.1.noarch.rpm.html Fedora] so may be a viable option, but would have to ask mentor.

Some initial research indicates some steps might include:
# Going through a getting started with Pbuilder (or other packaging tool)
# Building the RTEMS Toolset in the chrooted environment
# writing a script that uses templates to build the RTEMS Toolset and RTEMS in a chrooted environment:
## download the source and Debian patches from [http://ftp.de.debian.org/debian/pool/main/ Debian]. (apt-get source binutils gcc newlib gdb) 
## apply the Debian patches
## apply the RTEMS patches
## configure the packages
## satisfy the build dependencies (build-dep)
## build the package

The RTEMS Project currently does not have a computer running a Debian based GNU/Linux distribution and would have to have one before these could be supported long term.=  Additional References  =
