bcrypt's Issues

Fails to compile on OTP 23 due to erl_interface.h

OTP 23 deprecated erl_interface and this package now fails with:

SmartOS / Solaris

@Licenser and @siepkes we have released 1.1.0 - but I now realize that our new Makefile (based on erlang-mk) does not include any special options for Solaris or SmartOS.

Could you have a look?

Hex release

Would you consider a 1.1.5 release for Hex to incorporate #26?

Reconfigure at runtime

Hello!

Is there a way to reconfigure this library at runtime? It seems that the application env is read when the process pool is started so future changes to the configuration do not get used.

Thanks,
Louis

Build instructions

experience if missing C compiler dependencies is not very good.

After someone setups for elixir development, this is the experience:

==> bcrypt_elixir
could not compile dependency :bcrypt_elixir, "mix compile" failed. Errors may have been logged above.

There's no errors above. that is all the output. And this is a essential beginner step from the official guide.

I not that familiar with erl/rebar development but i can help if guided.

Error on Ubuntu 18.04.4 with Erlang 11.0.2 OTP23

I get this error when trying to use this on Ubuntu.
Assume there is some mismatch on underlying version of software installed, but what?
Anybody have any ideas on this?

{ok, Salt} = bcrypt:gen_salt().
** exception exit: {noproc,{gen_server,call,
