Up until a few days ago everything worked with OCaml 4.02.3, which is the OCaml version supported by rmem.
When I try to build linksem (make LEM=<path_to_lem>) with OCaml 4.02.3 I get this:
[..]
File "byte_sequence_wrapper.ml", line 77, characters 2-11:
Error: Unbound value List.init
[..]
(List.init was introduced in 4.06.0)
Best,
