Description

Hi,

I'm maintaining erlang for Arch Linux. Recently, our package for erlang 19.3 was patched in connection with the upgrade to OpenSSL 1.1.0. Normally we don't patch packages but try to keep them as close to the upstream release as possible, but this was security related and therefore prioritized. Most things related to Erlang continued to work fine, but CouchDB didn't and a bug was reported in the Arch Linux bug tracker.

3 days ago, Erlang released version 20.0 rc1, which included the desired changes related to OpenSSL 1.1.0. I released a version of this package to [community-testing]. This looks promising.

As far as I am aware, the current situation is that couchdb does not run on Arch Linux at all, right now.

When compiling couchdb with Erlang 20.0 rc1, I get:

==> couch_epi (compile)
ERROR: OTP release 20 does not match required regex R16B03|R16B03-1|17|18|19
ERROR: compile failed while processing /build/couchdb/src/apache-couchdb-2.0.0/src/couch_epi: rebar_abort
make: *** [Makefile:67: couch] Error 1

Please support Erlang 20.0.
