Install from Source (Mac OS X)

This document will help you install and run Matterhorn on the Mac OS X operating system. Tested on OS X 10.9 Mavericks.

The installation on Mac OS X is not officially supported. Use this at your own risk.

Preparation

Create Matterhorn installation directory

sudo mkdir -p /opt/matterhorn
sudo chown $USER:$GROUPS /opt/matterhorn

Check out Matterhorn source

You can get the Matterhorn source code by either downloading a tarball of the source code or by cloning the Git repository. The latter option is more flexible, it is easier to upgrade and in general preferred for developers. The prior option, the tarball download, needs less tools and you don't have to download nearly as much as with Git.

Using the tarball:

Select the tarball for the version you want to install from https://bitbucket.org/opencast-community/matterhorn/downloads#tag-downloads

# Download desired tarball
curl -O https://bitbucket.org/opencast-community/matterhorn/...
tar xf develop.tar.gz
mv opencast-community-matterhorn-* /opt/matterhorn/

Cloning the Git repository:

cd /opt
git clone https://bitbucket.org/opencast-community/matterhorn.git
cd opencast
git checkout r/2.0.x

Using Homebrew

Homebrew is a package manager for OS X. For installation instruction see their website.

brew install maven
brew install ffmpeg
brew install apache-activemq
# Optional
brew install tesseract
brew install hunspell
brew install sox

Using pre-built binaries

Pre-built versions of most dependencies can be downloaded from the respective project website:

• Get Apache Maven
• Get FFmpeg
• Get Apache ActiveMQ

Building Opencast

Compile the source code:

cd /opt/matterhorn
mvn clean install -DdeployTo=/opt/matterhorn

Please be patient, as building matterhorn for the first time will take quite long.

Configure

Please follow the steps of the Basic Configuration guide. It will help you to set your host name, login information, etc. As specified in the guide, make sure you replace the default ActiveMQ configuration with the one provided in docs/scripts/activemq/activemq.xml. If you installed ActiveMQ using homebrew, you can find the installation path with brew info activemq.

Running Opencast

Make sure you have ActiveMQ running (unless you're running it on a different machine). Then you can start Opencast using the start-matterhorn script.

activemq start
cd /opt/matterhorn
sudo ./bin/start-matterhorn
