Installing PyLucene 4 (4.5.1)

Greetings friends!

Here I'm going to show you how to install/setup pylucene 4.x on linux - ubuntu or debian

Why are we installing pylucene 4?

This may be your first time using lucene with Python, or you may be upgrading.  pylucene 4 adds faceting features, and reworks the module structure to be identical to that of lucene 4 itself.  Check out the samples directory after you download the pylucene package for examples of new and existing functionality.

Install PyLucene

Download pylucene from http://lucene.apache.org/pylucene/install.html

Extract the Package:

tar -zxvf pylucene-4.5.1-src.tar.gz

Install openjdk:

sudo apt-get install openjdk-7-jdk

Install Apache Ant:

sudo apt-get install ant

Install gnu c++ compiler:

sudo apt-get install g++

Install python dev (python.h) headers:

sudo apt-get install python-dev

Upgrade/install setuptools to 0.7 or higher:

sudo apt-get install pip 

pip install setuptools --upgrade 

Change to the jcc directory:

cd pylucene-4.5.1-1/jcc  (edit to match your extracted directory)

Build and Install JCC:

sudo python setup.py build

sudo python setup.py install 

If all that worked, you're ready to build pylucene!

# cd up to the "pylucene-4.xxx" directory 

cd .. 

Edit the file named "Makefile" located at the root of the pylucene-4.5.1 directory you just extracted

# Locate this line

# Linux     (Ubuntu 11.10 64-bit, Python 2.7.2, OpenJDK 1.7, setuptools 0.6.16)

Uncomment lines in the Makefile as shown (if you are on linux):

Issue make and install command:

make 

sudo make install  

 Test the installation:

# open a python interpreter 

python 

# now at the prompt type... 

import lucene 

lucene.initVM()

 If no exceptions are raised you're done!  You've now installed PyLucene 4 !
