Error while parsing configuration file: Eliom: XXX.cma: (Failure "SSL is required\n")

Trying to use sociaml-oauth-client lib (which uses cohttp), I can not run my server. It fails at startup.

I tried to pin the cohttp branch, but it won't install:

And now, I am lost.

No idea where the SSL is required comes from. I can't find anything like that in our source code.

A priori, there is no conflict between using the "old" Ocsigenserver with libraries that use Cohttp as a client; we do the same in BeSport.

I am looking into the deflatemod build failure.

[vasilisp]

The deflatemod installation issue should be fixed. Any help with testing the cohttp branch appreciated :). Not that you will also need the cohttp branches for Eliom et al.

The SSL message is a mystery for me as well. Couldn't find it in packages I directly use...

Installation issue is indeed fixed now.
