Hi nickva, thanks for your reply.
Indeed it seems that our packager patched the source to build couchdb

But what I don't understand is, the dependency page
(https://docs.couchdb.org/en/3.1.1/install/unix.html#dependencies) mentions
Erlang OTP 19.x as requirement. Do I don't understand the line "Erlang OTP
(19.x, 20.x >= 21.3.8.5, 21.x >= 21.2.3, 22.x >= 22.0.5)" or is this
information wrong? Since it is comma sparated, I assumed that 19.x is fully
supported...
What Erlang version should we try? 22 or should we already try the latest,
eg 24? Since 24 is not mentioned in the list I guess we should go with 22,
right?
Regards
Mathias
