DistroKit
---------
This is the main repository for DistroKit, an Embedded Linux Board
Support Package (BSP) for the PTXdist [1] Build System.
The main task for PTXdist is to build a root filesystem and a flash
image for the embedded system. PTXdist has a concept of separating the
software configuration from the hardware platforms, so the first
decision to be made is to select for which hardware DistroKit shall be
built.
Installing PTXdist
------------------
DistroKit is built with ptxdist. In order to install ptxdist, download
the tarball from [2]:
$ wget \
http://www.pengutronix.de/software/ptxdist/download/ptxdist-2013.05.0.tar.bz2
Extract the tarball:
$ tar xf ptxdist-2013.05.0 && cd ptxdist-2013.05.0
Go to the extracted directory and run
$ ./configure && make && sudo make install
Selecting the Platform
----------------------
For the different hardware platforms, see the instructions about
- how to install the toolchain
- how to select the right platform
- how to build the rootfs
in README.<platform>.
In order to build a BSP, you need a toolchain. The easiest way to get a
toolchain is to install the debian packages for OSELAS.Toolchain:
http://www.pengutronix.de/oselas/toolchain/
If you want to build the toolchain yourself, you can download the
toolchain sources from
http://www.pengutronix.de/oselas/toolchain/download/
and build them manually.
Building DistroKit
------------------
Now everything is prepared to build the BSP:
$ ptxdist go
PTXdist determines the number of CPUs on your computer and runs the
compiler with <twice the number of CPUs> instances in parallel.
Nevertheless, building a root filesystem from the sources needs some
time.
