It is a statically linked Linux binary which (if successful) will print "hello, world" and exit cleanly. On qemu-arm64 userspace emulator it doesn't print anything and loops forever using 100% CPU. ---- ---- The following section is only if you wish to compile this binary from source, otherwise you can ignore it. First compile OCaml from: https://github.com/ocaml/ocaml (note you have to compile it on aarch64 or in qemu, it's not possible to cross-compile). You will have to apply the one-line patch from: https://sympa.inria.fr/sympa/arc/caml-list/2013-12/msg00179.html ./configure make -j1 world.opt Then do: echo 'print_endline "hello, world"' > test.ml ./boot/ocamlrun ./ocamlopt -I stdlib stdlib.cmxa test.ml -o test ./test To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1263747/+subscriptions
