Re: [MirageOS-devel] Problem compiling Jitsu

Jitsu doesn't use ezjsonm directly. It looks like the constraint is correct for Irmin 0.9.9 though [1] -- shouldn't ezjsonm 0.4.1 have been installed automatically when Irmin was pinned?
(Could also be related to [2])

Thanks -- is there a bug open for the ezjsonm constraint as well?  The older versions of Jitsu should all have upper bounds to prevent the conflicting libraries from being selected.

Thank you for the quick reply! I got it working now. I had to also pin the ezjsonm to 0.4.1.
> opam pin add ezjsonm 0.4.1
Thanks guys!

Hi guys,
Can anybody help with this? I have problem compiling mirage/jitsu on Ubuntu.
# File "irmin_backend.ml", line 39, characters 65-88:
# Error: Unbound type constructor Irmin.t
# make: *** [/home/user/.opam/4.01.0/build/jitsu.0.2/bin/jitsu] Error 2
This error is caused by a recent API change in Irmin 0.9.10 and will be fixed in the next version of Jitsu.
As a temporary solution you can pin Irmin to version 0.9.9 with 'opam pin add irmin 0.9.9'. You should then be able to install Jitsu with 'opam install jitsu'.
I have submitted a PR to add a version constraint in opam [1], but it may take some time before it is merged and propagated.
