# Building an Image from source
|
|
|
|
|
This project is written in the programming language Elixir and built using the
|
|
|
|
|
Nerves Project framework.
|
|
|
|
|
|
|
|
|
|
## Before you begin
|
|
|
|
|
You will need a number of things before we start.
|
|
|
|
|
* A Linux machine
|
|
|
|
|
* A x64 bit machine
|
|
|
|
|
* probably about 16 gigs of ram
|
|
|
|
|
* about ~30 gigs of hard drive space
|
|
|
|
|
* a fairly recent cpu
|
|
|
|
|
|
|
|
|
|
## Install dependencies
|
|
|
|
|
If you have the above set up you will need some software dependencies.
|
|
|
|
|
* Elixir found [here](http://elixir-lang.org/install.html)
|
|
|
|
|
* Nerves Bootstrapper found [here](https://hexdocs.pm/nerves/installation.html#Linux)

|
## Set up environment
|
|
|
|
|
We are going to set up the environment for building Farmbot OS
|
|
|
|
|
```bash
|
|
|
|
|
mkdir farmbot
|
|
|
|
|
cd farmbot
|
|
|
|
|
git clone https://github.com/FarmBot/farmbot_os.git os
|
2017-04-03 09:03:19 -06:00
|
|
|
cd farmbot_os
|
2017-02-27 00:33:59 -07:00
|
|
|
npm install
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## Compile the application
|
|
|
|
|
From here you will have to choose your own adventure. You get to choose if you
|
|
|
|
|
want development mode or production mode, and you get to choose the target you
|
|
|
|
|
want to build the executables for. see the [ENVIRONMENT](environment.html) for more details
|
|
|
|
|
This will take a while depending on you machine.
|
|
|
|
|
```bash
|
|
|
|
|
export MIX_ENV=prod
|
|
|
|
|
export MIX_TARGET=rpi3
|
|
|
|
|
mix deps.get
|
|
|
|
|
mix firmware
|
|
|
|
|
```
|
