See the X/Qt jumbo section for more details. You will need X/Qt if you want to run awt or swing.
Note: You should install automounter [automounter-c3000_0.5.0_arm.ipk] which automates the
creation of additional loop devices and mounting of the cramfs images.
The java cramfs also has HdPad and HdCrawler pre-installed as well as kopi and jikes compiler, and
tools from the GNU classpath project.
Java Alternatives
There is a way to run Java 1.4.x applications on the Zaurus through a Java compatible runtime such
as JamVM. JamVM is not officially endorsed nor certified to be Java compliant, but it is able to run
most Java 1.4.x and even 1.5 applications. JamVM uses libraries from the GNU classpath project to
run Java applications.
jEdit can be run using JamVM:
JamVM GUI applications (AWT and Swing) require a X/Qt environment for display.
gcc
If you want to develop and compile your own C/C++ applications then you will need gcc. There are
basically two flavours of development for the Zaurus. You can develop on the Zaurus itself using the
on-board or native gcc compiler to build your application binaries or use a cross compiler to build
your applications from a PC. The on-board development is particular useful for small applications.
However, for larger applications, the Zaurus might not be powerful enough unless you want it
sitting on a desk compiling your applications continuously for days. In order to use a
cross-compiler, you would need a x86 based PC or something that is powerful enough to emulate it.
There are several cross compile toolchains which allow you to compile applications for the Zaurus.
One of the easiest to setup and getting started with is the kopsis toolchain
(http://kopsisengineering.com/kopsis/SharpZaurusSdkDsl) which uses the DSL (Damn Small Linux)
Live CD technology allowing you to boot the CD and have a ready development environment or use
the CD image from a x86 emulator such as qemu, bochs or vmware. There is a great vmware image
