xen generates multiple definitions of the same function in shared-memory-ring and mirage-xen These functions are caml_cstruct_unsafe_load_uint32, caml_cstruct_unsafe_save_uint32 and caml_memory_barrier.

Looks promising! I'm still hoping that someone will figure out the build as part of functoria, with a clean separates between the "generic" part and the "mirage" part. It's not necessary at all, but since you are actively working on the topic, the idea can sit in the corner of your mind. ;) |
Use files setup by ocaml-freestanding instead.

I'm creating this PR in order to track the modifications of the mirage CLI I've made for #969.
mirage config -t <target>creates adunefile with all the rules needed to build the end user unikernel. This allowsmirage buildto be very simple (equal todune build @target) and take full advantage of dune incremental builds.Using variants, less packages will need (unix-freestanding-xen) specialization but this requires an update of packages that have C stubs.
One good indicator of this working fine is the
mirage/mirage-dev#duneCI on mirage-skeleton. It doesn't pass yet but it should improve as we dufiny packages.
