build failure on Linux through OPAM

[sanmai-NL]

The problem seems straightforward:

===== ERROR while installing ocaml-top.1.1.2 =====
# opam-version 1.1.1
# os           linux
# command      ocp-build -init -scan

I can confirm that I get the same problem on Linux and on Mac (See #50)

This happens with ocp-build 1.99.8 (rather than 1.99.6)

@AltGr

BTW this is the default ocp-build that gets pulled down when doing an opam install ocaml-top .

[AltGr]

Yes, actually I had a PR for that some time ago but it got stalled for some reason; should be OK now if you opam update. Thanks for reporting !

It does not seem OK for OCaml 4.02, as ocp-build-1.99.6-beta requires ocaml < 4.02. ocaml-top still fails with ocp-build-1.99.8-beta .

[zoggy]

The problem is still there...

[sidkshatriya]

If you pin to an older version of ocp-build (e.g. 1.99.6) using opam pin, you can build this.

[zoggy]

I can't:

# opam install ocp-build.1.99.6-beta
The following dependencies couldn't be met:
  - ocp-build -> typerex
Your request can't be satisfied:
  - typerex is not available because it requires OCaml < 4.02.0.

I used ocaml 4.01
