=======================================
| Eurovision -- Let it Sparkle/Sparql |
=======================================
| Compilation/Installation            |
---------------------------------------

--
1. Requirements
--
Core command-line tools used by Greenstone3 are:

  svn
  make, autoconf, gcc, g++
  ant, javac
  libz, imagemagick, wget

Sgvizler2 in the Apache Jena extension uses:

  npm, nodejs


These can be installed on a Debian10 distribution, for example,
with:

  sudo apt update
  sudo apt install subversion build-essential openjdk-11-jdk ant libz-dev, imagemagick wget
  sudo apt install npm
  
For editing config files, our preference is to use emacs:

  sudo apt install emacs

--
2. Environemts Variable Settings
--
For the above Debian10 setup, set the following environment variables:

  export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
  export PATH=$JAVA_HOME/bin:$PATH

  export CFLAGS=-fPIC
  export JAVACFLAGS="-source 1.6 -target 1.6"

Adjust for your specific environemnt as necessary

--
3. Checkout and Prepare core Greenstone3 system
--
  svn co https://svn.greenstone.org/main/trunk/greenstone3 greenstone3-svn
  cd greenstone3-svn

To generate a default 'build.properties'

  ant

To check out GS2 building code:

  ant prepare


Edit build.xml line 722 from:

  <condition property="gs2.opt.args" value="${opt.gnomelibext.arg} " else="--disable-mg --disable-mgpp --disable-accentfold --disable-gdbm --disable-sqlite">
to:
  <condition property="gs2.opt.args" value="${opt.gnomelibext.arg} --disable-wvware " else="--disable-mg --disable-mgpp --disable-accentfold --disable-gdbm --disable-sqlite">

--
4. Test you have an operational Greenstone3 base DL server:
--
  source ./gs3-setup.sh
  ant start

In your browser, visit:

  http://localhost:8383/greenstone3/library

If working on a remote compute, such as a Google Compute Engine, use its console/dashboard
to look up the IP number of the machine, and also add in a firewall rule to open up
port 8080

  ant stop
  
--
5. Checkout and compile the Apache Jena Triplestore extension:
--
  svn co https://svn.greenstone.org/gs2-extensions/apache-jena/trunk/src gs2build/ext/apache-jena

  pushd gs2build/ext/apache-jena/
  ./CASCADE-MAKE.sh 
  popd

--
6. Test your Sparql endpoint:
--
Run the Triplestore server:

  gs-triplestore-server3
  
In a browser visit:

  http://localhost:4040

Similar note about to the one above in (4) if setup/access is on/to a remote machine

Stop gs-triplestore-server3 by pressing Control-C

Roadmap:
