`opam publish` now works with OCaml 4.06

opam

#1

I am happy to announce that since https://github.com/ocaml/opam-repository/pull/11416 has been merged, opam publish will now work with 4.06.

Happy opam publishing!


#2

Hum actually there are still more problems (related to opam-lib 1.2.2), so this is not ready yet. Sorry for the noise.


#3

Any progress on this? We currently can’t install opam-publish on 4.06.0.


#4

The only missing steps is porting opam-lib 1.3 to 4.06 (contributions are welcome).

A workaround is to install opam-publish in a different switch using 4.05. As it is a plugin, it will automatically be exposed in other switches as well.


#5

Actually it seems like opam-lib 1.3 is working fine on 4.06. So you can install opam-publish by doing:

$ opam pin add opam-lib.1.3.1 https://github.com/ocaml/opam.git#1.3.1
$ opam install opam-publish

I have submitted a PR to remove the constraint, not sure why it was set in the first place.


#6

Indeed, works great for me. Thanks a lot Thomas!

I’m getting a build error:

That trace is too small; could you try to enable verbose mode (or to look at the stdout/stderr files) to get the real error?

Which version of jbuilder do you have? This looks like an issue which was present in beta17.


#11

I was on jbuilder beta18. Upgrading to beta20 fixed the problem. Thanks for the help.
