How to fix compilation error from Cowboy examples?

Question

Erlang

I'm trying to compile a Cookie example from Cowboy examples, but I get an error:

..................................................
Finished in 16.335 seconds
770 tests, 0 failures
 ERLC   cookie_app.erl cookie_sup.erl toppage_handler.erl

Crash dump was written to: erl_crash.dump
init terminating in do_boot ()
make: * [ebin/cookie.app] Error 1

Has anyone experienced something similar?

Answer 1

{undef,[{merl,term,[<<237 bytes>>],[]}
says he didn't find merl:term
rebar get-deps did ?

Answer 2

I partially solved the problem by moving merl from the erlydtl dependencies folder to /usr/local/lib/erlang/lib/, but the question remains why erlang does not find merl in the application's dependencies?
