How do I install a driver in Erlang? (Specifically MySQL-otp driver) - mysql

Question

From the documentation this driver looks great. I don't know how to install it so that I can use it though. I read somewhere that I should maybe use rebar? I looked at that documentation though and it appears to have the opposite problem. It says how to install it, but not how to use it.
Update
So it looks like after installing rebar, I can add the lines
{deps, [
{mysql, ".*", {git, "https://github.com/mysql-otp/mysql-otp",
{tag, "1.3.3"}}}
]}.
to my file rebar.config. I don't know what this does though. Do I have to compile or make this file now? Does rebar.config have to be in the same directory as my project? Right not the path to rebar.config is ~/rebar/rebar.config
Is it all correct to place my project so that it is a sibling to rebar in the file hierarchy?
Update
I ran ./rebar get-deps with the rebar folder and got
Pulling mysql from {git,"https://github.com/mysql-otp/mysql-otp",
{tag,"1.3.3"}}
Cloning into 'mysql'...
==> mysql (get-deps)
I still don't really know what this means though, and when I try compiling my erlang file I receive the result.
c(erlangFile.erl).
{error,non_existing}

Answer 1

rebar is a build tool for erlang.Please go through https://github.com/rebar/rebar/wiki/Rebar-commands for the commands.
After getting dependency, "rebar compile" is required to compile it.
For using the beam files, you have to give output beam path using Add Path to Erlang Search Path?
these methods.
Then you will be able to use it in your code.

Answer 2

Download your package, in this case
git clone https://github.com/mysql-otp/mysql-otp.git
Download a tool called rebar
git clone git://github.com/rebar/rebar.git
cd rebar
./bootstrap
Add the following to rebar/rebar.config
{deps, [
{mysql, ".*", {git, "https://github.com/mysql-otp/mysql-otp",
{tag, "1.3.3"}}}
]}.
Within the rebar/mysql-otp directory run
./rebar get-deps
Then within the same directory, run
./rebar compile
This will put a bunch of .beam files and .app file into the ebin/ directory
Next add the ebin/ directory to your path. You can update your $ERL_LIBS environment variable, run an include command within the erlang console like
1> code:add_pathz("~/rebar/mysql-otp/ebin").
or
1> code:add_pathz("rebar/mysql-otp/ebin")
And theres a few other ways to add it to your Erlang path.
Also, make sure mysql is also installed
