Interesting -- these are both new symbols introduced in cstruct.1.6.0. I had thought that the Cstruct stubs in mirage-platform were now using the version from Cstruct, but that transition hasn't happened yet. It's easily fixed; you can either: - test the fix via "opam pin add mirage-xen git://github.com/avsm/mirage-platform#fix-cstruct-1.6.0" (you need OPAM 1.2.1+ for this, as it uses the virtual package detection feature) - drop back to Cstruct.1.5.0 via "opam install cstruct.1.5.0" - the upper bounds are added in this opam-repository pull request: https://github.com/ocaml/opam-repository/pull/3978 thank for the report! -anil _______________________________________________ MirageOS-devel mailing list [email protected] http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel
