I think this series is going the right way but there seems to be quite a lot of breakage introduced to the cross compiles: https://app.shippable.com/github/stsquad/qemu/runs/939/summary/console I guess there is more subtlety involved when host !=3D target. I'd recommend setting up a shippable account: https://wiki.qemu.org/Testing/CI/Shippable You can of course just run: make docker-test-build J=3Dn And watch your machine slowly grind through all the options. -- Alex Benn=C3=A9e
