Bug 601906 – dev-ml/opam: dependency cycle with jsonm, topkg, uchar, uutf

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Sergey 'L29Ah' Alirzaev 2016-12-07 15:24:09 UTC]

I cannot provide a legal ordering for the following:

n   dev-ml/jsonm:0::gentoo 1.0.0 to ::installed [cycle 1]
    "Non-blocking streaming JSON codec for OCaml"
    build_options: symbols=compress -dwarf_compress -optional_tests -trace work=tidyup
    Reasons: dev-ml/opam-1.2.2-r1:0::gentoo
    In unsolvable cycle with dev-ml/jsonm:0, dev-ml/opam:0, dev-ml/topkg:0, dev-ml/uchar:0, dev-ml/uutf:0

I solved it by installing first jsonm-0.9.1 and uutf-0.9.4. Those two do not depend upon opam so there is no dependency cycle.

Anyway it should be fixed.

I just did the same and it worked for me as well.  To note, I needed to install uutf-0.9.4 first and then jsonm-0.9.1 in that order to avoid the circular dependency.  That said, until this is fixed, it really breaks ocaml installations since we can't pull from opam without going through some odd hoops.

This should do it I think. Please reopen if there is anything I've missed.
