You may or may not really want to do this.... There's always a chance when compiling software and using ppa's that you run a risk in creating an unstable, possibly unusable machine. I am sure that you know this already, but for other folks that may happen upon this post, you might not want to do this...
Here is what I did in order to install the latest version of media-explorer (media-explorer-0.3.4). I added the prague-demo ppa.
sudo add-apt-repository ppa:zdra/prague-demo
This allowed for me to install all of the required dependencies that I was unable to resolve using my standard default repositories. I then updated my apt sources by running the following:
sudo apt-get update
Here are the dependencies that are necessary to install in order to get the latest version of media-explorer to compile without errors. To install them run:
sudo apt-get install intltool libclutter-1.0-dev libsoupcutter-dev libmx-dev libgrilo-0.1-dev libgstreamermm-0.10-dev libclutter-gst-dev liblircclient-dev libtracker-sparql-0.10-dev libavahi-glib-dev librest-dev libavahi-client-dev
Download the tar file from media-explorer's site:
tar -xvf media-explorer-0.3.4.tar.xz
Then cd into the Directory:
./configure --prefix=/usr && make && sudo make install
You should then be able to launch
media-explorer. There were a couple of warnings that appeared in my terminal, I am not familiar with this application, but do plan to play around with it a bit now!
