Sure, but once you've done the build you've got everything you need. Some classes are generated differently, depending on the word size of the target machine. > 2) - Isolate a subset of the sources to get gcj-openjdk port > started. possibly: java.lang.* (and all dependancies) at first, then the > other fundamental things; java.io.*, java.util.* etc. Although open for > suggestions here of course. The core classes and class loaders are all gcj custom and highly intertwined, so you'd better avoid those. > 3) - Compile the pieces from 2) with GCJ, add in more packages as > things build. > > 4) - Somehow, maintain releases for it all as things progress, so > people can grab current work and collaborate.

Alternatively, we could use classpath.org, but that machine is rather heavily loaded already. Andrew.
