# Prerequisites to using the Release Kit code base


  * Java JDK       (min v1.6, typically v1.8 used, known to work with v1.11)
  * Apache ant     (min 1.8.2)
  * C/C++ compiler (e.g., g++ for Linux, Microsoft Visual Studio for Windows, XCode for Mac)
  * Subversion     (min v1.8)

Under Linux (to be confirmed why it is needed)

  * Set the LANG environment variable to use UTF-8, e.g., export LANG=en_NZ.UTF-8


To use the Release Kit scripts, some source code needs to be compile first:

  ant compile

And the Release Kits 'bin' directory added to your PATH.  For example:

  export PATH=$PWD/bin:$PATH

Finally, for compilation compilation of JNI code in Greenstone3 to be able to
locate the necessary header files (e.g., jni.h), JAVA_HOME needs to be set,

For example (on Ubuntu 32-bit):

  export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-i386


To create a release, for example Greenstone 3 v3.11rc:

  mkdir releases
  cd releases
  echo "version:3.11rc" > rk3-build.properties
  rk3
