If you try to build an old QEMU on a new distro like this you're likely to run a bunch of minor build bugs that have been fixed in mainline. You will probably need to trawl through the git history or the mailing list archives to find the relevant commits which fix them (searching for error messages is often a good tactic). You should also choose configure options to minimise the amount of source you build that you don't need. If you only need qemu-system-ppc64, then pass configure the "--target-list=ppc64-softmmu" argument and it will build only that and won't try to build the linux-user code at all. If configure of that vintage supports --disable-tools that is also going to be useful (and if some bit of source that looks uninteresting fails check to see if there's a relevant --disable-something to just stop building it.) thanks -- PMM
