Standard GNU tools (such as
bash,
ls, etc) are available in the
MontaVista?
distribution at
ftp://ftp.mvista.com/pub/CDKit/1.2/latest/PowerPC
Even if you are compiling them yourself, you can use the recipe in the %build
portion of the SPEC files in the =SRPM=s to help.
Also known as
sash, this is a small standalone shell with minimal versions of
the most useful commands from
/bin built in. See
http://www.canb.auug.org.au/~dbell/programs/sash-3.4.tar.gz
Not to be confused with the
CONFIG_SASH configuration option in many kernels,
which starts a shell at bootup with the proper process group settings, so that
signals like interrupt on
CTRL-C work. Note that the two are often used
together.
http://busybox.lineo.com/
BusyBox combines tiny versions of many common UNIX utilities into a single
small executable. It provides minimalist replacements for most of the utilities
you usually find in
fileutils,
shellutils,
findutils,
textutils,
grep,
gzip =, =tar, etc.
BusyBox provides a fairly complete POSIX
environment for any small or embedded system. The utilities in
BusyBox?
generally have fewer options than their full-featured GNU cousins; however, the
options that are included provide the expected functionality and behave very
much like their GNU counterparts.
There are stacks to choose from. Here are just a few, which seem particularly
well-suited to embedded Linux work. Pick the one that has the features you
need.
http://www.boa.org/
Boa is a single-tasking HTTP server. That means that unlike traditional web
servers, it does not fork for each incoming connection, nor does it fork many
copies of itself to handle multiple connections. It internally multiplexes all
of the ongoing HTTP connections, and forks only for CGI programs (which must be
separate processes), automatic directory generation, and automatic file
gunzipping. Preliminary tests show Boa is capable of handling several thousand
hits per second on a 300 MHz Pentium and dozens of hits per second on a lowly
20 MHz 386/SX.
http://www.acme.com/
A collection of very small web servers, with varying degrees of functionality.
http://microwindows.censoft.com/
Microwindows is an Open Source project aimed at bringing the features of modern
graphical windowing environments to smaller devices and platforms. It allows
applications to be built and tested on the Linux desktop, as well as
cross-compiled for the target device.
http://pgui.sourceforge.net/
A small, portable, client/server GUI designed to work on many types of hardware
including handheld computers. Includes layout manager and widgets.
MontaVista have several JVM solutions for
HardHatLinux.
A list of Java virtual machines, some of which are suitable for embedded
PowerPC systems, is available at
