compilation errors with erlang 20

[rolfn]

I tried to compile erica with erlang 20. There are many error because of changed functions like "crypto:md5_init" or "crypto:md5_final". After replacing all obsolete functions with the new ones I get a erica binary. Unfortunately it throws

Uncaught error in erica: {'EXIT',
                             {undef,
                                 [{couchbeam,start,[],[]},
                                  {erica_core,run,1,
                                      [{file,"src/erica_core.erl"},{line,41}]},
                                  {erica,main,1,
                                      [{file,"src/erica.erl"},{line,12}]},
                                  {escript,run,2,
                                      [{file,"escript.erl"},{line,759}]},
                                  {escript,start,1,
                                      [{file,"escript.erl"},{line,277}]},
                                  {init,start_em,1,[]},
                                  {init,do_boot,3,[]}]}}

Now I don't know what to do. Can you help? Many thanks in advance.
