===========================================================================

This is Kaffe, a virtual machine design to execute Java bytecode.
|
|
This machine can be configured in two modes. In one mode it operates as
|
|
a pure bytecode interpreter (not unlike Javasoft's machine); in the second
|
|
mode if performs "just-in-time" code conversion from the abstract code to
|
|
the host machine's native code. This will ultimately allow execution of
|
|
Java code at the same speed as standard compiled code but while maintaining
|
|
the advantages and flexibility of code independence.
|
|
|
|
Running Kaffe
|
|
=============
|
|
Before running Kaffe it is necessary to configure the environment.
|
|
This requires the setting of CLASSPATH, KAFFEHOME and LD_LIBRARY_PATH.
|
|
For the standard installation these would be defined as follows:
|
|
|
|
CLASSPATH=.:/usr/local/share/kaffe/classes.zip
|
|
KAFFEHOME=/usr/local/share/kaffe
|
|
LD_LIBRARY_PATH=/usr/lib:/usr/local/lib
|
|
|
|
A file "ENVIRONMENT" is generated by the configure program which contains
|
|
a /bin/sh environment setup. This may help you to figure out what to
|
|
set to what if you alter the standard installation point.
|
|
|
|
The state of play
|
|
=================
|
|
Kaffe should run all non-graphical code which will run on a Java
|
|
machine. However there are still bugs and plenty of untested native
|
|
library functions. Some functions which are not currently implemented
|
|
(most often because I don't understand exactly what they are suppose to
|
|
do) will simply abort if called. If you can help out on any of these
|
|
then please do *BUT* remember, this is a clean-room implementation (I
|
|
have never seen any of Sun's Java source code) and I cannot simply
|
|
encorporate Javasoft's* code.
|
|
|
|
For further info see the file README that comes with the distribution.
