tyxml, ocsigenserver and eliom are incompatible with OCaml 4.00.0

[0branch]

These packages reference Netstring_pcre which is no longer provided by ocamlnet.3.6. Given that ocamlnet.3.5.1 is incompatible with OCaml 4.00.0, these packages ought to declare ocaml-version: [ < "4.00.0" ].

Related question: any suggestions for the best patching strategy? One option would be to substitute Netstring_pcre with Netstring_str where applicable, repackage and distribute with a modified version number e.g., tyxml.2.1p. (I still need to test this for ocsigenserver and eliom, works for tyxml.) An alternative would be tracking the development heads of each project (via a Github mirror as they're versioned with darcs).

Hello,
ocamlnet.3.6 still supports PCRE it is just not enabled by default anymore; from the ocamlnet's ChangeLog:

2012-07-19 Gerd Stolpmann gerd@samsung

* The default is now -disable-pcre

Frederic has a fork of opam-repository with a package ocamlnet-all which provides ocamlnet, version 3.6, with PCRE, though, waiting to be pulled.

Does this fix?

Aha, thanks for the info Benedikt—I overlooked that. Will try Frederic's repository now.

Yes @tuong repository contains some important fixes, we'll try to merge it today or at the beginning of next week.

Hmm, can't see ocamlnet-all in @tuong's repo (I'm probably doing something dumb). Instead, I added @benozol's fork as a remote and successfully built tyxml against the PCRE enabled ocamlnet.

Next problem: ocsigenserver requires Dbm (--with-dbm is a default configure flag). To build with 4.00.0, either:

1. A dependency on CamlDBM should be added or
2. --without-dbm should be supplied in ocsigenserver.2.1.opam

I think (1) is preferable?

[tuong]

It is the branch frederic-master : https://github.com/tuong/opam-repository/tree/frederic-master .
You can then opam install ocsigen_tutorial .

Thanks @tuong. I see the dbm stuff is addressed too—perhaps we should close this ticket?
