Boblight for Arch Linux ARM / Raspberry Pi

Overview

This is my personal edit of the original boblight software which can be found at: https://code.google.com/p/boblight/

I updated the v4l client code to work with the newer ffmpeg (>0.8) libraries provided in Arch Linux.

Added some additional optimizations from Speedy1985's Boblight repository. This code means that using the standard boblight.conf will no longer work and you must use 3 character naming for lights as per the example boblight.conf inlcuded here.

I have also fixed a few other V4L related bugs as reported on the boblight issues list.

Integrated makeboblight.sh configuration helper script as per enchancement issue 24

Installing

Assuming you are starting with a base image of Arch Linux for Raspberry Pi (ArchArm) you will need to install the following dependencies using Pacman to compile this code:

git, gcc, make, libx11, libxrender, portaudio, libxext, mesa, glu, ffmpeg

This can be done with the following command:

pacman -Sy git gcc make libx11 libxrender portaudio libxext mesa glu ffmpeg bc

To install: ./configure && make && make install

If you want v4l support use ./configure --with-v4l

After installing it create a boblight.conf in /etc as per the official documentation: Boblight Config

Create a new ld config file in /etc/ld.so.conf.d/ as usr-local.conf and add /usr/local/lib to it.

Run ldconfig

Create a systemd service for the boblight daemon if you are running the damon on this Pi, for example:

vi /usr/lib/systemd/system/boblight.service

Description=Boblight Ambient Lighting Daemon
DefaultDependencies=no
After=network.target

[Service]
ExecStart=/usr/local/bin/boblightd
Restart=on-abort

[Install]
WantedBy=multi-user.target

systemctl enable boblight

systemctl start boblight

At this point the boblight daemon and all clients should be working.

Troubleshooting

If you receive following error after executing make:

g++: internal compiler error: Killed (program cc1plus) Please submit a full bug report, with preprocessed source if appropriate. See https://github.com/archlinuxarm/PKGBUILDs/issues for instructions. Makefile:533: recipe for target 'libboblight_la-boblight_client.lo' failed make[2]: *** [libboblight_la-boblight_client.lo] Error 1 make[2]: Leaving directory '/root/boblight/boblight-archarm/src' Makefile:345: recipe for target 'all-recursive' failed make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory '/root/boblight/boblight-archarm' Makefile:254: recipe for target 'all' failed make: *** [all] Error 2

increase the memory by adding swap space:

Write virtual swap disk

dd if=/dev/zero of=/root/swap bs=1M count=512

Set permissions

chmod 600 /root/swap

Setup swap

mkswap /root/swap

Activate swap

swapon /root/swap

try to compile again: make && make install
