Debian at least have put a lot of work into getting cross-compilers installed as part of the native distro with good multi-arch support. We now use plain Debian 9 for most of the QEMU cross compiles - a few older architectures still need Debian 8 with the emdebian overlay. > I haven't looked at the docker tests, is this running tests/tcg test > somehow? No but as tests/tcg are all pretty simple and have less cross-compile dependencies than QEMU itself it is fairly trivial to invoke docker to do a cross-build for you in-place. e.g.: docker run --rm -t -u (id -u) -v (pwd):(pwd) -w (pwd) qemu:debian-armhf-cross arm-linux-gnueabihf-gcc tests/tcg/hello-arm.c This is perhaps a bad example as there is a bit-rot that needs fixing. The alternative is to mine the users PATH for fairly standard cross-compile prefixes which work at least on Debian systems. I recently submitted a patch to RISU that allowed you to use either in its build-all-arches script: https://git.linaro.org/people/peter.maydell/risu.git/tree/build-all-archs -- Alex Bennée
