Js-of-ocaml code fails with "Base_am_testing not implemented" about ppx_inline_test HOT 5 CLOSED

Confirming that the upgrade to v0.9.0 causes this, and js_of_ocaml reports:

There are some missing primitives
Dummy implementations (raising 'Failure' exception) will be used if they are not available at runtime.
You can prevent the generation of dummy implementations with the commandline option '--disable genprim'
Missing primitives:
  Base_am_testing

from ppx_inline_test.

this is coming from base (https://github.com/janestreet/base/blob/711aa92e22ba8904e9a247666c7caabcdd711682/src/import0.ml#L246).

You should be able to get the right runtime.js with
js_of_ocaml +base/runtime.js main.byte

@hhugo So I tracked down why I am using base; and it's because now the dependencies have been "inverted" Sexplib now depends on Base http://opam.ocaml.org/packages/sexplib/sexplib.v0.9.0/. But why?

from ppx_inline_test.

@smondet we made this decision for two reasons:

1. so that Base can use S-expression and still have no dependency
2. so that the code of Sexplib can benefit from using Base

(2) was one of the reason we started Base. There is a lot of code in the libraries that come before Core_kernel: sexplib, bin_prot, typerep, ... And often when we improved a standard thing in Core_kernel, the code before it didn't benefited from the improvement. Having Base as the root package allows to desgin all of the codebase using the same base.

I believe this is fixed by the latest JaneStreet releases. reopen if you still have issues.
