Zaurus custom Linux
The purpose of the ZAULUX project is to build a custom Linux distribution
for the Sharp Zaurus SL-6000.
Description
ZAULUX is derived from the OpenZaurus Linux, both created by the
OpenEmbedded meta distribution.
The purpose of the OpenEmbedded Project is to provide an universal framework to synthesize
Linux distributions for different PDA like devices. It consist of an collection of "blueprints"
containing the necessary information to cross-compile the software for the target platform. It
will also create and set up the tools needed for this task.
These "blueprints" are called "bitbake (.bb)" files named after the bitbake tool. This tool is
comparable to "emerge" of the gentoo distribution or more loosely to the GNU utility "make".
A bitbake file is made up at least of a short description and an URL pointing to the source of
the software to be compiled. Additional it is possible to add a list of dependencies for
the particular software package so bitbake can satisfy those dependencies by
building the needed packages first.
The bitbake tool provides default functions to unpack, compile and install the software. If these
default actions are unsuitable for the software (i.e. the software does not follow the
"configure && make && make install" concept) it is possible to overwrite them, utilizing any standard
shell functions.
To create a Linux distribution the OpenEmbedded Enviroment utilizes the bitbake files together with
a profile for the target platform. The result is an image file and a kernel, ready to be copied to
the system.
