Raspberry Pi

ENiGMA½ can run under your Linux / RPi installation! The following instructions should help get you started.

Tested RPi Models

###Model A Works, but fairly slow (Node itself is not the fastest on this device). May work better overlocked, etc.

##Example Configuration: RPi Model A + Minibian

Basic Instructions

1. Download and dd the Minibian .img file from https://minibianpi.wordpress.com/ to a SDCARD. Cards >= 16GB recommended.
2. After booting Minibian, expand your file system. See http://elinux.org/RPi_Resize_Flash_Partitions#Manually_resizing_the_SD_card_on_Raspberry_Pi for information.
3. Update & upgrade: apt-get update && apt-get upgrade
4. It is recommended that you install sudo and create an admin user: apt-get install sudo, adduser <yourname>, adduser <yourname> sudo (reboot & login as the user your just created)
5. We want to build dependencies with a updated version of GCC. The following works to install GCC 4.9 on Minibian "wheezy": a. Update /etc/apt/sources.list replacing all "wheezy" with "jessie" b. sudo apt-get update c. sudo apt-get install gcc-4.9 g++-4.9 d. Update /etc/apt/sources.list reverting all "jessie" back to "wheezy" e. sudo apt-get update f. Update alternatives: sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.9
6. Install dependencies: sudo apt-get install make python libicu-dev libssl-dev git
7. Install the latest Node.js from here: http://node-arm.herokuapp.com/ (only download the .dep and dpkg install it!)
8. The RPi A has very low memory, we'll need a swap file: a. sudo dd if=/dev/zero of=tmpswap bs=1024 count=1M b. sudo mkswap tmpswap c. sudo swapon tmpswap
9. Clone enigma-bbs.git
10. Install dependencies. Here we will force GCC 4.9 for compilation: CC=gcc-4.9 npm install
11. Follow generic setup for creating a config.hjson, etc. and you should be ready to go!
