This version of Kaffe is not supplied with a copy of Sun's class library.
|
|
|
|
|
This can be obtained from Sun's JDK package (from http://www.javasoft.com) or
|
|
|
|
|
pre-prepaired in kaffe-0.5.5-sun.tgz (from the usual Kaffe ftp sites).
|
|
|
|
|
This version of Kaffe uses the class library from JDK 1.0.2.
|
|
|
|
|
|
|
|
|
|
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:

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 source comes with a test program "HelloWorldApp" which can be found
|
|
|
|
|
in the test directory in the distribution. After installation, run this
|
|
|
|
|
program from the test directory by typing the following:
|
|
|
|
|
|
|
|
|
|
cd <java source directory>/test
|
|
|
|
|
kaffe HelloWorldApp
|
|
|
|
|
|
|
|
|
|
This should load and execute the HelloWorld application. If all is well
|
|
|
|
|
it will print "Hello World!". As a further test you might like to try
|
|
|
|
|
compiling the HelloWorldApp source. To do this type the following:
|
|
|
|
|
|
|
|
|
|
javac HelloWorldApp.java
|
|
|
|
|
|
|
|
|
|
"javac" is a shell script which has been provided to invoke Kaffe on
|
|
|
|
|
the standard Java compiler. If all is well, the application should compile
|
|
|
|
|
without incident.
