Linux Additional Notes

Additional notes related to the Linux Setup preocess.

Gnome over remote SSH

It seems that the "owner" of the ".dbus" folder in a users home area can be set to "root" during the update process. This will mean that you will get a lot of errors when trying to use any graphical programs remotely over ssh. This problem can be fixed by running the following command in your home area:

sudo chown -R UserName:UserName .dbus/

Flash

The required flash plugin can be installed through firefox. When the user goes to a site that requires a flash plugin an install option is offered.

Adobe Flash Plugin: has been tried and seemed to work well.

Vmware Tools

If you have installed Ubuntu within a vmware virtual machine you will also need to run the following two lines to get the vmware tools to build properly.

sudo ln -s /lib/modules/YourInstalledKernel/build/include/generated/utsrelease.h
  /lib/modules/YourInstalledKernel/build/include/linux/utsrelease.h

sudo ln -s /lib/modules/YourInstalledKernel/build/include/generated/autoconf.h 
  /lib/modules/YourInstalledKernel/build/include/linux/autoconf.h

D2R

• Not been checked for 12.04
• The D2R-Server binaries can be downloaded directly from their website. I downloaded the newest binary, which at the time of writing was http://downloads.sourceforge.net/project/d2rq-map/D2R%20Server/v0.7%20%28alpha%29/d2r-server-0.7.tar.gz?use_mirror=kent d2r-server-0.7.tar.gz].
• Unpack the software directory from the downloaded file and move it to a good location, such as /usr/local/. I also set up a version free symbolic link to the downloaded folder, though I am not sure it will be needed.

tar xzvf d2r-server-0.7.tar.gz
sudo mv d2r-server-0.7 /usr/local/. 
ln -s /usr/local/d2r-server-0.7 /usr/local/d2r-server

• A quick setup guide can be found here.
• Details about setting up the D2R-Server under Tomcat can be found here. You will need to install ant for this.

sudo apt-get install ant

• Further details, links and documentation can be generally found through the D2R-server website.

Sesame

• The Sesame binaries can be downloaded directly from the openrdf website. I downloaded the newest sdk binary, which at the time of writing was openrdf-sesame-2.2.4-sdk.tar.
• Unpack the software directory from the downloaded file and move it to a good location, such as /usr/local/. I also set up a version free symbolic link to the downloaded folder, though I am not sure it will be needed.

tar xzvf openrdf-sesame-2.2.4-sdk.tar
sudo mv openrdf-sesame-2.2.4 /usr/local/. 
ln -s /usr/local/openrdf-sesame-2.2.4 /usr/local/openrdf-sesame

• Copy the openrdf-sesame.war and openrdf-workbench.war files into the Tomcat webapps directory and restart Tomcat.

sudo cp /usr/local/openrdf-sesame/war/openrdf-sesame.war /usr/local/apache-tomcat/webapps/.
sudo cp /usr/local/openrdf-sesame/war/openrdf-workbench.war /usr/local/apache-tomcat/webapps/.
/usr/bin/local/apache-tomcat/bin/shutdown.sh
/usr/bin/local/apache-tomcat/bin/startup.sh

• If everything installed correctly opening your browser to http://localhost:8080/openrdf-workbench should present you with a "List of Repositories".
• Further information can be found at the openrdf website.

4store (RDF Triple Database system):

• sudo apt-get install build-essential libpcre3-dev libglib2.0-dev ncurses-dev libreadline-dev libavahi-common-dev libavahi-client-dev libavahi-glib-dev

raptor and rasqal in stadard repository are probably ok, but description on the 4store website recommends the specific build instructions listed below. --Jpadfield 10:28, 10 November 2009 (UTC)

Then need to download and build from source the following packages; (or the newest stable versions)

1. raptor2-2.0.2.tar.gz
2. rasqal-0.9.25.tar.gz

• • Ideally Rasqal should be built with ./configure '--enable-query-languages=sparql rdql laqrs'

1. 4store-v1.1.2.tar.gz
