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
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.
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
