issue with eiconv

[jschoch]

not sure if this is somehow related to hex

14:31:43.337 [error] The on_load function for module eiconv returned {{:badmatch,

Hi @jschoch, Do you have libiconv installed?

[HashNuke]

@jschoch B/w love your blog, done in exdoc :) Sweet idea ~!

[jschoch]

ya, just playing around a bit, not much of a blogger.

anyway, ya i have libiconv installed, and i can run iconv. It seems someone put a lot of work into libiconv detection here, but that also doesn't work: processone/eiconv

here is the test output from that.

[]$ make test
./rebar skip_deps=true eunit
==> eiconv (eunit)

some env tests, i'm going to try on another box to see if i can reproduce

 sudo ldconfig -v |grep iconv
libiconv.so.2 -> libiconv.so.2.5.1

ldd $(which iconv)

@jschoch by tomorrow's end I'll have an Ansible playbook to setup an Elixir stack on Ubuntu. I have a project with gen_smtp, so if iconv is a problem, I'll hit it too and fix it.

[jschoch]

what does iconv actually do in mail-to-json?

[HashNuke]

@jschoch encoding/decoding. Actually used by gen_smtp - https://github.com/Vagabond/gen_smtp/blob/fb667c6ed875be1ae8d5ea0fa74eb9043fd7ecc7/src/mimemail.erl

I think I included it because I was using an updated version.
