jsoo 3.0

[meadofpoetry]

As far as I can see js_of_ocaml, js_of_ocaml-ocamlbuild and js_of_ocaml-ppx are sufficient for successful building.

This doesn't work here. It seems they renamed js_of_ocaml to js_of_ocaml.exe (!?). But somehow the ocamlbuild plugin was not updated.

Thanks for you help @Freyr666.

Note that if this manages to get fixed upstream then it seems we don't need to make a new release. We should simply update the constraints in the opam-repository. But please keep this open for now.

Ah, I see. It seems we also need js_of_ocaml-compiler package. At least I have js_of_ocaml binary along with the js_of_ocaml.exe, and vg compiles just fine. I've added js_of_ocaml-compiler in deps, does it work now?

[dbuenzli]

This doesn't work here the build fails as above with:

> opam list | grep js_of_ocaml 
js_of_ocaml             3.0           Compiler from OCaml bytecode to Javascript

js_of_ocaml-ppx         3.0           Compiler from OCaml bytecode to Javascript

on which platform are you ?

on which platform are you ?

fedora 26, amd64. That is strange since

$ which js_of_ocaml
~/.opam/main/bin/js_of_ocaml
$ js_of_ocaml --version
3.0
$ opam list | grep js_of_ocaml

Thanks I now understand the issue, see the monologue here https://github.com/ocsigen/js_of_ocaml/issues/613. In any case your constraints are in as 29277f4db8524234b177f504dea7f2 and I submited https://github.com/ocaml/opam-repository/pull/10056 on the opam repo to make vg.0.9.0. use jsoo 3.0. Thanks for the help.
