I've written up how to get minimal rt.jars using the old (which changed since the big GNU Classpath merge in CVS after 1.1.6) build system here: http://article.gmane.org/gmane.comp.java.vm.kaffe.general/6240/match=kaffe+rt+jar+size > Any hints on how to easily reduce rt.jar would be appreciated. > It would > help if "--with-awt=no" would actually not include any awt and swing > packages in rt.jar. That's a rather hard problem, since there are both native and Java dependencies for something like AWT. So to cleanly separate things, one would need to keep both the native code and the java code makefiles up to date. I've tried maintaining class library profiles by hand in the past, and that sort of work is not much fun, since the class library is evolving so quickly. I am not aware of any tool that can generate adequate makefiles with correct dependency information for both C and Java code automatically. I've played with early releases of http://www-out.bell-labs.com/project/nmake/release/jdeps.html a few years ago without much success, see http://kaffe.org/pipermail/kaffe/2003-October/044289.html for details. The tools probably have improved since, so if you feel like giving it a shot, please tell us how it went. > I don't need (and I'm guess most embedded > platforms) graphics, sound, xml, rmi, applet, corba (and security for > now). A single switch for a minimal rt.jar would be nice. Yeah. While classpath's build system also has support for excluding class from the build, I think the simplest way to create minimal rt.jars for applicatons should to use one of the various bytecode munging tools made for that. An Ant task, for example, that 'packs' a jar is available at http://sadun-util.sourceforge.net/pack.html If you try it out, please report back how it worked. cheers, dalibor topic _______________________________________________ kaffe mailing list kaffe@kaffe.org http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
