I am looking to use Java on an Xscale processor on Linux and I am looking at JamVM and Kaffe. You mentioned that Kaffe on an Xscale 'still has problems'. Can you describe the problems? Perhaps a couple of us can hammer out some of these issues and make Kaffe really solid for the Xscale processor.

I've had same success with this configuration: ./configure CFLAGS=-I/opt/cross/armv5b-linux/include --prefix=/wrk/moxa --build=i686-linux --host=armv5b-softfloat-linux --enable-xscale --without-x --disable-alsatest --disable-esdtest --disable-sound --enable-pure-java-math --with-jikes=/opt/local/bin/jikes --without-classpath-gtk-awt --without-kaffe-qt-awt --without-kaffe-x-awt --with-threads=unix-pthreads --with-engine=intrp --with-libffi --with-staticbin --enable-debug --enable-xdebugging (You may not need all of these parameters, for example I use --with-staticbin because my armv5b has an ancient version of glibc). You can find my earlier experiences of using kaffe on big endian arm from this thread: (including responses, which I got from from this excellent community ;) http://pogo.kaffe.org/pipermail/kaffe/2004-August/099397.html Besides Kaffe, another Java environment that works on armv5b is gcj. Both have several problems though :( Cheers, Jari On Wed, 6 Oct 2004, Thomas Winkler wrote: > Hello, > > I'm currently trying to compile kaffe for the the intel XScale (ARM, > Big Endian). > I tried kaffe 1.1.4 as well as kaffe CVS HEAD (20041006).
