Free Java : is native code the way?
I'm pleased to announce that I was successful in compiling the XML (hence the
copy to debian-sgml) parser "xp" in native code with gcj.
This means that we can run any application built over this XML parser without
a Java virtual machine (we have two such machines in 'potato', the non-free
JDK and the free kaffe, which fails on this parser, bug #51263).
This withdraws a serious objection against Java ("Java is not really free
since we depend on Sun's virtual machine") and another one against XML ("All
the XML software is written in Java and therefore not really free").
Thanks a lot to the gcj team, I hope you will go on!
gcj fails on many Java constructs, and cannot compile "xp" directly. I had to
compile with jikes (which is a free program, also), and use gcj to convert
bytecode to native code. The entire sofwtare chain is free. Here is the nice
command line to build the executable :-)
ezili:~/infosystems/XML/Java> gcj --main=UnTag UnTag.java UnTagHandler.java
Next step: compiling the "xt" XSL processor, which is built over "xp". It
doesn't work at the first try, which means everything is not done yet.
