eiri commented on issue #611: Compilation issues with Erlang 20
URL: https://github.com/apache/couchdb/issues/611#issuecomment-310663728
 
 
   For what it's worth this seems to be a problem with your spider monkey installation, rather than with couch itself, it is technically possible to compile it with erlang 20
   
   ```bash
   vagrant@sandbox:/tmp$ kerl active
   The current active installation is:
   /opt/erlang/20.0
   
   vagrant@sandbox:/tmp$ git clone https://github.com/apache/couchdb.git
   Cloning into 'couchdb'...
   remote: Counting objects: 67715, done.
   ...
   
   vagrant@sandbox:/tmp$ cd couchdb/
   vagrant@sandbox:/tmp/couchdb (master)$ 
   
   vagrant@sandbox:/tmp/couchdb (master)$ ./configure --disable-fauxton --disable-docs
   ==> configuring couchdb in rel/couchdb.config
   Cloning into '/tmp/couchdb/src/rebar'...
   remote: Counting objects: 367, done.
   ...

   You have configured Apache CouchDB, time to relax. Relax.
   
   vagrant@sandbox:/tmp/couchdb (master)$ vi rebar.config.script
   ## add 20 to require_otp_vsn
   
   vagrant@sandbox:/tmp/couchdb (master)$ vi src/snappy/rebar.config
   ## add 20 to require_otp_vsn
   
   $ make
   ==> config (compile)
   Compiled src/config_sup.erl
   Compiled src/config_app.erl
   ...
   Compiled src/rexi_sup.erl
   Compiled src/rexi.erl
   ==> rel (compile)
   ==> couchdb (compile)
   ``` 
   
   That said erlang 20 hasn't been tested and not recommended for use, hence it's not in `require_otp_vsn`.
