compiling a SWT-gui with gcj on windows

[Jörg Maisenbacher <joerg at maisenbachers dot de>]

Hy,

 We are working on a new gui for mldonkey (you know, the p2p-app for 
linux). We do this in Java and SWT, to avoid the peoples fear of slow 
Java-software, we want to complile it with gcj.

 Here is, where my problem starts. I only get errors when compiling the 
libraries we use. (boot.jar jface.jar runtime.jar swt.jar trove.jar)

 As i'm not very experienced with gcc and its command-line switches, i 
don't know wether it is my fault, or a bug in the windows-port. Perhaps 
you can help me (or at least give me a hint) how to compile a more 
complex piece (which means quite a lot of classes and external .jar as 
libs) of software using gcj.

I hope you can help me and our project.

greets
Joerg Maisenbacher


PS, i put an example here: (using the gcc 3.4 package from 
http://www.thisiscool.com/gcc33_mingw.htm )
for example:
> gcj -fjni --CLASSPATH=%CP% -c jface.jar

(where %CP% =
xmlParserAPIs.jar;
xercesImpl.jar; boot.jar;
runtime.jar; swt.jar; jface.jar)

results in:
