I didn't actually run any tests, since they require more dependencies. - bash has to be installed explicitly. configure/meson do not check for it, but the build will fail if they aren't present. - linux-user binaries can't be compiled because alpine's usage of musl; I didn't look much more closely. Takeaways: - You really don't need a lot to build a minimal QEMU. Even the alpine package list is pretty small. - meson seems to be handling "absolutely everything is missing" environments pretty well. - There are a scant handful of dependencies that could be added to configure, but you are very likely not to be missing them, so it's low priority. --js
