noproc gen_server call error

[solatis]

Hello,

I must be doing something wrong, since the example on the site is not working. Consider the following:

lmergen@laptop ~/git/ebitcoind $ bitcoin-cli getbalance
0.00000000
lmergen@laptop ~/git/ebitcoind $ erl -pa ebin deps/*/ebin
Erlang/OTP 17 [erts-6.4.1.2] [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V6.4.1.2  (abort with ^G)
1> {ok,Pid} = ebitcoind:start_link().
{ok,<0.35.0>}
2> ebitcoind:getbalance(Pid).

I tried debugging this issue, but am kinda in a dead end, given I'm quite new to erlang. As seen above, I'm running erlang 17. Googling suggest there might be something wrong with the way the link is stored. Is this perhaps an erlang version compatibility issue ?

My inexperience at work here. I had to start inets like this:

inets:start().

before invoking any ebitcoind commands.

Add it as a dependency to your existing rebar project.
