OLA on Linux

This describes how to get OLA working on a Linux system either from the git repo or by using a released tarball.

Checkout or Download an Archive

Either download a tarball from the releases page, or check out the git repo with the following command:

 git clone http://www.nomis52.net/git/lla

If you don't have git yet, you'll need to install it with your distro's package manager.

Install libraries

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 up you'll need the following:

• cppunit
• uuid or ossp uuid
• pkg-config
• curses

Debian/Ubuntu users can install them with apt:

 apt-get install libcppunit-dev libcppunit-1.12-1 uuid-dev pkg-config libncurses5-dev

If you're building from git you'll also need the following:

• libtool
• automake
• autoconf

 apt-get install libtool autoconf automake

Next, you need Protocol Buffers http://code.google.com/p/protobuf/ version 2.1.0 or above from Google (BSD license) version must NOW be > 2.3.0. Most likely, you'll need to download and build them yourself.

Debian (and Ubuntu) users can, in some cases, use the following packages (not yet in stable): libprotobuf2 (libprotobuf3), libprotobuf-dev, protobuf-compiler

Finally, if you want to use the built in webserver, you'll need microhttpd and ctemplate. Note: you'll need version >= 0.4.0 of microhttpd else you will get errors:

• ftp://ftp.gnu.org/gnu/libmicrohttpd/
• http://code.google.com/p/google-ctemplate/

Once everything is installed, run ldconfig as root to pick up the new libraries

 sudo  ldconfig

Configure

If you checked out the sources from git, you'll need to run

 autoreconf -i

After that run

 ./configure

Building & Testing

Build

 make

If you get an error like the following:

/bin/sh ./libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I.   -I/opt/local/var/macports/software/protobuf-cpp/2.0.3_0/opt/local/include/  -g -O2 -c -o ltdl.lo ltdl.c
./libtool: line 464: CDPATH: command not found
/Users/simonn/lighting/lla/libltdl/libtool: line 464: CDPATH: command not found
/Users/simonn/lighting/lla/libltdl/libtool: line 1142: func_opt_split: command not found
libtool: Version mismatch error.  This is libtool 2.2.6, but the
libtool: definition of this LT_INIT comes from an older release.
libtool: You should recreate aclocal.m4 with macros from libtool 2.2.6
libtool: and run autoconf again.

Your system uses a different version of libtool. Run:

 libtoolize --ltdl -c -f

and then start from the autoreconf step again.

Run the tests

 make check

And install OLA

 sudo make install
 sudo ldconfig

Install ola-examples

The OLA Command Line Tools come separately. Again either download a tarball or checkout from the git repo:

 git clone http://www.nomis52.net/git/lla-examples

The steps are similar to building the main package.

  autoreconf -i   # if you used the git repo
  ./configure
  make
  sudo make install

Note in order for ola_dmxmonitor and ola_dmxconsole to build you *must* have curses installed.
