OK. After I've rebuilt libstdc++6, libffi, libgcc1, libpcre3, and linux-libc-dev (but not eglibc yet) we get to an installable state. So I followed the instructions on https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/arm64bootstrap to set up a raring chroot. (And note that the pinning in /etc/apt/preferences.d/bootstrap is still needed until I rebuild eglibc too, which needs a profile patch updating, so I've skipped it for now) (Stop at 'Use with sbuild' because you are not doing that, but building upstream source directly in the chroot). Then I entered the chroot with schroot -c raring-amd64-sbuild and inside did: sudo dpkg --add-architecture arm64 sudo apt-get update sudo apt-get install libglib2.0-dev:arm64 zlib1g-dev:arm64 libpixman-1-dev:arm64 sudo apt-get install crossbuild-essential-arm64 (27MB of stuff) sudo apt-get install python ./configure --target-list=arm-softmmu --cross-prefix=aarch64-linux-gnu- for that configure to work you need http://patchwork.ozlabs.org/patch/243412/ So that gives a cross-environment that satisfies the qemu configure. You need other patches from that series for it to actually build, but I'll leave it to you from here :-) Thanks to Peter Maydell for supplying qemu runes and patches. Complain if this doesn't get you going. Notes: Don't install sbuild inside the chroot - that can break things. A couple of wiki pages have been updated in this process, but a lot more updating is needed to make this properly easy. I notce that the start page: https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/CrossbuildingQuickStart doesn't really cover this case of building 'not-packaged stuff, using multiarch', and clearly it should. And the page on 'multiarch crossbuilding' is woefully out of date. If I was being snarky I might point out that this would already have been working and up-to-date when you wanted to use it if people hadn't insisted that this work was not wanted and I should stop. Still, it didn't take long to get going, and fortunately you don't need anything that we haven't built yet.
