Building irmin FS store on Mirage Os unikernel

I am trying to build a irmin FS store on mirage OS.

module Store = Irmin_unix.Git.FS.KV(Irmin.Contents.String)
      (* Database configuration *)
      let config = Irmin_git.config ~bare:true "/tmp/irmin/test" 

      (* Commit author *)
      let author = "xyz <>" 

      (* Commit information *)
      let info fmt = ~author fmt 

But I am getting the below error.

Error: No implementations provided for the following modules:
Checkseum referenced from /home/sahana/.opam/4.06.0/lib/decompress/impl/impl.cmxa(Impl__Decompress_safe),
Digestif referenced from /home/sahana/.opam/4.06.0/lib/git/git.cmxa(Git__Mem),
Command exited with code 2.

Should I pass the file as a device or something. Not sure what the error means.

I posted a solution at the GitHub Irmin’s issue: :slight_smile:
