This describes how to get OLA working on a Beaglebone from strach. At the time of writing, an "image" does not exist for the beagle bone. This process is based on using the debian os.
Contents
Preparing your debian based Beaglebone
Install dependencies
You need a couple of libraries installed for everything to work correctly. Some of these are available as packages in distros but others need to be downloaded and built manually.
First you'll need at least the following:
- cppunit
- uuid or ossp uuid
- pkg-config
- curses
- lex (or flex)
- yacc (or bison)
- the protocol buffers library http://code.google.com/p/protobuf/ (version 2.3.0 or later)
- microhttpd ftp://ftp.gnu.org/gnu/libmicrohttpd/ (if you want the web UI). You need version >= 0.4.0 of microhttpd
If you're building from git you'll also need the following:
- libtool
- automake
- autoconf
sudo apt-get install libcppunit-dev libcppunit-1.12-1 uuid-dev pkg-config libncurses5-dev libtool autoconf automake g++ libmicrohttpd-dev libmicrohttpd5 protobuf-c-compiler libprotobuf-lite6 python-protobuf libprotobuf-dev zlib1g-dev bison flex make libftdi-dev libftdi1 libusb-1.0-0-dev liblo-dev
Note, these dependancys are slightly different from the Debian build
Tarball
Download the most recent tarball from http://code.google.com/p/open-lighting/downloads/list Extract using
tar -zxf ola-0.X.Y.tar.gz cd ola-0.X.Y
Git
If you don't have git yet, you'll need to install it with your distro's package manager. On Debian / Ubuntu run:
sudo apt-get install git
Check out the git repo with the following command:
git clone https://code.google.com/p/open-lighting/ ola cd ola
Run autoreconf
If this is the first time run with -i to install the missing files
autoreconf -i
Do the usual build steps
You can pass additional options to ./configure . Run
./configure --help
to see all options. The most popular option is --enable-python-libs to build the Python Client Module. If you want to use the RDM responder tests add --enable-rdm-tests.
Once you've decided on the options, it's time to build OLA. If you have a multi-core machine, you can speed up the build by using make -j N. A good value of N is the number of cores on your machine. On a MacBook Pro (4 core) using -j 4 reduced the build time from 5 minutes to 2.5 minutes.
./configure --enable-rdm-tests make make check sudo make install
Finally run ldconfig so you can use the new libraries.
sudo ldconfig
Device drivers
Note that, for some devices, it is necessary to install drivers for OLA to work with them. For example, the Open DMX USB device needs an additional kernel module that could be built using the instuctions on LLA_and_Q_Light_Controller_Ubuntu_Tutorial. For other devices, refer to the corresponding device page on this wiki.
