I'm not sure what point you're trying to make in 2-4 in regards to building a freebsd-ppc version of OpenJDK. Could you expand on that? FWIW, the current version of openjdk7 does build on MacOS X/PPC using the Zero VM. You can download binaries here: http://www.intricatesoftware.com/OpenJDK/macppc/openjdk7u2-macppc-fcs-2012-03-14.tar.bz2 Given that Zero works on FreeBSD (or did last time I tried) and the PowerPC build for Zero works on other supported OSes, it doesn't seem like there would be a lot of code changes required to get it to to work on FreeBSD/PPC. The biggest hurdle is likely the first time bootstrap. I believe I've previously sent out links on how to go about the first time bootstrapping. It's not trivial but it's doable. You are, of course, free to work on whatever you want. I'm just trying to suggest what I think has the highest chance of getting you a working JDK on FreeBSD/ppc in a reasonable time. > I have to build on both Debian and FreeBSD to see where errors occur.

I trimmed freebsd-current since my reply doesn't seem relevant for it. -- Greg Lewis Email : glewis@eyesbeyond.com Eyes Beyond Web : http://www.eyesbeyond.com Information Technology FreeBSD : glewis@FreeBSD.org
