Irmin on xen - current state

[hannesm]

it doesn't compile anymore... bin_prot (used by mirage-tc) needs to be patched (as you did here for a 112.35 version https://github.com/samoht/bin_prot/tree/112.35.00+xen), mirage-tc has an upper bound on bin_prot < 113.01.00, but pa_sexp_conv requires (via type_conv) a bin_prot >= 113.00.00.

any plan to remove or upgrade the bin_prot dependency from mirage-tc (or remove the mirage-tc dependency from irmin)?

[hannesm]

the above relationship between bin_prot and type_conv is wrong. an old type_conv requires an old bin_prot, and pa_sexp_conv is not happy with that type_conv

[hannesm]

(mirage-tc should be fine with newer bin_prot ocaml/opam-repository#6205)

[hannesm]

and for bin_prot I started to add a xen sublibrary at https://github.com/hannesm/bin_prot/tree/113.33.00+xen but somehow I do not manage to convince the build system thereof to compile and install it...

[hannesm]

solved: https://github.com/hannesm/bin_prot/tree/113.33.00+xen now works (compiles, installs the xen sublibrary as wel); and using the result I can link a Canopy unikernel! :)

[hannesm]

would nevertheless be nice to get an opinion from @samoht about bin_prot...

[samoht]

I'm in favour of making that dependency optional.
