Installing Greenstone from a binary distribution (Linux):
---------------------------------------------------------

Download the gsdl3-x.xx-linux executable file, and run it. Follow the instructions given.

Installing Greenstone from a binary distribution (Windows):
-----------------------------------------------------------

Download the gsdl3-x.xx-win32.exe executable file, and double click on it. 
Follow the instructions given. 


Installing Greenstone from a CVS checkout (Linux and Windows):
--------------------------------------------------------------

Checkout the code:

cvs -d :pserver:[email protected]:2402/usr/local/global-cvs/gsdl-src co gsdl3

Build and install:

Greenstone is built and installed using Ant (Apache's Java based build tool, 
http://ant.apache.org). You will need a Java Development 
Environment (1.4 or higher), and Ant installed to use Greenstone. You can download Ant from http://ant.apache.org/bindownload.cgi. Set the environment variable JAVA_HOME to be the root of your Java installation. We recommend Sun's Java. Greenstone 3 has not been tested with other types of Java.

In the gsdl3 directory, you can run 'ant' which will give you a help message.
Running 'ant -projecthelp' gives a list of the targets that you can run - these
do various things like compile the source code, startup the server etc.

For a first time install, run 'ant prepare install'.

The file build.properties contains various parameters that can be set by the user. Please check these settings before running the install.

Greenstone uses the Tomcat servlet container. If you already have Tomcat running, you can set the tomcat.installed.path property to the base directory of your Tomcat installation, and Greenstone will not download its own Tomcat.
It is intended that the same thing will be available for mysql, but this has not been implemented yet.

Greenstone 3 uses some parts of Greenstone 2 for collection building using the Librarian Interface. It downloads the relevant parts during install. If you have Greenstone 2 already installed, please set the gsdl2.installed.path property to be the root of your Greenstone 2 installation. Greenstone 3 will then use this installation rather than downloading the extra Greenstone 2 bits. If you do not want to use Greenstone 2 style collection building at all, set the gsdl2.installed.path to any non-empty string.

 The prepare target will ask you if you accept the properties before starting.
To suppress this prompt, use the -Dproperties.accepted=yes flag. E.g.
ant -Dproperties.accepted=yes prepare install

To log the output in build.log, run
ant -Dproperties.accepted=yes -logfile build.log prepare install

The prepare target will download additional code, so you need to be online to run it. install can be run offline.

Under Linux, Java and C/C++ compilation is carried out. For windows, since Visual Studio is not a standard component, only Java compilation is carried out. Pre-compiled binaries are provided for the C/C++ components (packages and Greenstone 2 style building). If you have Visual Studio installed (version 6), you can run the compile-windows-c++ targets to compile the code locally. (Don't forget to setup the Visual Studio environment first, by running, e.g. C:/Program Files/Microsoft Visual Studio/VC98/Bin/VCVARS32.BAT or equivalent.)

Common install/update targets.
-------------------------------
1. Install for the first time:
cvs co gsdl3
cd gsdl3
ant prepare install

2. Install for the first time, offline:
[online]
cvs co gsdl3
cd gsdl3
ant prepare
[offline]
ant install

3. Install for the first time, cvs done outside of Ant (if you have problems running cvs commands from Ant):
cvs co [-P] gsdl3
cd gsdl3
cvs update -P (run this if you haven't done the checkout with the -P option)
cd packages
cvs co mgpp
cd ..
[if you want greenstone 2 building:
cvs co -P gli
cvs co -P gs2build
]
[if you are on windows
cvs co winbin
]
ant -Dnocvs.mode=yes prepare install (prepare needs to be online, install can be done offline)

4. Updating your Greenstone installation from cvs (and reconfigure/recompile):
cd gsdl3
ant update

5. Updating your Greenstone installation, offline:
cd gsdl3
[online]
ant cvsupdate
[offline]
ant -Dnocvs.mode=yes update

6. Updating your Greenstone installation, cvs outside of Ant:
cd gsdl3
cvs update -l
cvs update -dP bin comms docs lib resources src winutil packages 
cd web (or the path-to-tomcat/webapps/gsdl3 if have installed greenstone as a webapp in Tomcat, see Using External Tomcat section)
cvs update -dP 
cd gsdl3
[ if you have greenstone 2 building:
cvs update -dP gli
cvs checkout -P gs2build
Note that the gs2build one uses checkout not update.
]
ant -Dnocvs.mode=yes update

The main targets for installation/update are:
configure, configure-c++, clean, compile.
Any sub targets can be run by themselves. Run 'ant -projecthelp' for a list of public targets, otherwise you can look at the build.xml file to see which targets depend on other ones.

If you run your install using an external Tomcat, the SOAP web service for localsite (used by the gateway servlet) will not be loaded. You need to start up Tomcat, then run 'ant soap-deploy-site' and accept the defaults for sitename and siteuri (both localsite). If you want to use the gateway servlet without restarting Tomcat, you will need to reload the site information. Visit the URL localhost:8080/gsdl3/gateway?a=s&sa=c  (substituting your server name and port number if necessary). See the user guide for more information about run time reconfiguration.

Running Greenstone:
-------------------

To startup the local servers, run 'ant start'. 'ant restart' and 'ant stop' restarts and shuts down the servers. To start or stop just Tomcat or MYSQL, use the start-tomcat, start-mysql, stop-tomcat, stop-mysql targets.
These will only start/stop local servers (ones installed by Greenstone). You will need to manually start/stop external Tomcat/mysql.

On Windows, if you have installed a binary version, you can also start Greenstone by selecting Greenstone 3 Digital Library from the Start menu.

Greenstone will be available in a browser at "http://localhost:8080/gsdl3".

You can change the port number by changing the tomcat.port property in build.properties, then running 'ant configure'.


Using SOAP (Linux and Windows):
-------------------------------

Greenstone comes with Apache Axis installed as a webapp in Tomcat.  A SOAP server on localsite is deployed during installation. You should be able to see all localsite's collections through the gateway servlet.

To set up a SOAP server on a new site, run
ant soap-deploy-site
This will prompt you for the sitename (the directory name), and the site uri - this should be a unique identifier for the site's web service.

For a non-interactive version, run
ant -Daxis.sitename=xxx -Daxis.siteuri=yyy soap-deploy-site

Building Collections:
-----------------------

You can build collections using either Greenstone 2 style building, or native Greenstone 3 style.

Greenstone 2:

You need to have Perl installed and on your PATH.
run  'ant gli", or cd to gsdl3/gli and run gli4gs3.sh/bat. This is a graphical tool for building collections.

Greenstone 3:

In the gsdl3 directory, run: 'source gs3-setup.sh' (linux) or 'gs3-setup' (windows).
To create a new collection, run 'gs3-mkcol.sh/bat <sitename> <collname>'
Put documents in the import directory (gsdl3/web/sites/<sitename>/collect/<collname>/import), edit the collection configuration file (gsdl3/web/sites/<sitename>/collect/<collname>/etc/collectionConfig.xml), and run 'gs3-build.sh <sitename> <collname>'
Rename the building directory to index (in gsdl3/web/sites/<sitename>/collect/<collname>) and reload the collection in Tomcat (?a=s&sa=a&st=collection&sn=<collname>), or restart Tomcat.

See the manual for more details about both styles of collection building.

Other Notes:
---------------

See gsdl3/docs/manual/manual.pdf for more details about the software and installation etc.

Under Linux, Tomcat logs output in gsdl3/comms/jakarta/tomcat/logs/catalina.out.

To prevent Tomcat showing directory listings, edit the gsdl3/comms/jakarta/tomcat/conf/web.xml file and set the value of the "listings" servlet parameter to false.

ant can't seem to do cvs using authenticated cvs on windows:
there were some classes missing - www.ibiblio.org/maven/jsch/jars/jsch-0.1.17.jar
many ssh processes seemed to be started up - all waiting in the background for password??
So should only use anonymous cvs.

Using External Tomcat:
------------------------

If you want to use an existing Tomcat, set the path to its base directory
in build.properties (tomcat.installed.path). Then run 'ant prepare install'. If you have already done an install (e.g. using a local Tomcat), you don't need to do it again.

 You will need to modify the Tomcat setup slightly.

1. Tell Tomcat about the Greenstone web app. There are two ways to do this.

A. Add in the Greenstone context to Tomcat's server.xml. 

<Context path="/gsdl3" docBase="path-to-gsdl3/web" debug="1" 
reloadable="true"><Resources allowLinking='true'/></Context>

B. Alternatively, you can move (and rename) the gsdl3/web directory to tomcat/webapps/gsdl3 (i.e. the resulting directories will be like
tomcat/webapps/gsdl3/WEB-INF, no web directory). This should be done after running the initial 'ant prepare install'.
You will need to set the web.home property in the build.properties file
i.e.
web.home=${tomcat.installed.path}/webapps/gsdl3
And then run 'ant configure' to reset gsdl3home.

2. Set up the JNI libraries and Java wrappers.
JNI libraries and their Java wrappers cannot go into the web app. The libraries need to be loaded by the same class loader as their wrappers. The libraries need to be in java.library.path, and I think get loaded by the system class loader.
The wrappers need to be loaded by this too. 
To get the native libraries loaded, the directory they are in needs to be in the PATH variable (Windows) or the LD_LIBRARY_PATH variable (linux).

These JNI bits are located by default in the lib/jni directory. There are two ways to get them into Tomcat:
A: Keep all the Greenstone stuff inside the gsdl3 directory, and just modify the environment that Tomcat runs in

Set LD_LIBRARY_PATH (linux) or PATH (windows) to include the  gsdl3/lib/jni directory.
Add all the jar files in gsdl3/lib/jni directory to the CLASSPATH, then edit tomcats setclasspath.sh/bat to use the system CLASSPATH.
(in setclasspath.bat, change 
set CLASSPATH=%JAVA_HOME%\lib\tools.jar
to 
set CLASSPATH=%JAVA_HOME%\lib\tools.jar;%CLASSPATH%

in setclasspath.sh, change
# Set standard CLASSPATH
if [ "$1" = "debug" -o "$1" = "javac" ] ; then
  CLASSPATH="$JAVA_HOME"/lib/tools.jar
fi

to
# Set standard CLASSPATH
if [ "$1" = "debug" -o "$1" = "javac" ] ; then
  CLASSPATH="$JAVA_HOME"/lib/tools.jar:"CLASSPATH"
fi


B: Copy the files into Tomcat installation:
Move the gsdl3/lib/jni jar files into tomcat's shared/lib directory.
Move the gsdl3/lib/jni library files (.so for linux, .dll for windows) into shared/classes, and set LD_LIBARARY_PATH (linux) or PATH (windows) to include this directory. 
This has the advantage that you can use this for other webapps without modifying the Tomcat environment.


Once all these changes have been made, you will need to restart the Tomcat server for them to take effect.

Notes for Mac OS
------------------

Set JAVA_HOME to be /Library/Java/Home
