Installing the minimal or standard package on Linux or Mac OSX

If you already have locally-installed copies of Ant and the other required tools, install either the minimal or standard package.

Before you begin

Ensure that you have the following prerequisite software installed:

Ant, version 1.7.1 or later
Java runtime environment or development kit, version 6 or later
XSLT processor. You can use either Saxon, version 9.1 or later, or Xalan-J, version 2.7.1 or later.

In addition, determine the specific DITA-OT transformations that you intend to support and ensure that you have the prerequisite software installed for them.

For more information, see Prerequisite software and Tested platforms and tools.

Procedure

Download the minimal or standard package from SourceForge.

Package	File name
Minimal	DITA-OT1.8.5_minimal_bin.tar.gz
Standard	DITA-OT1.8.5_standard_bin.tar.gz

For production use, we recommend that you use the latest stable release.

Extract the contents of the package into an installation directory.

Note: You can extract the files either to your private home directory for your exclusive use or to the /usr/local/share/ directory, if you want to share the DITA-OT with other users.
Verify that the JAVA_HOME environment variable is set.
```
export JAVA_HOME=<JRE_dir>
```
Verify that the ANT_HOME environment variable is been set.
```
export ANT_HOME=<Ant_dir>
```
Verify that the PATH environment variable includes the Java and Ant executable files.
```
export PATH=$JAVA_HOME/bin:$ANT_HOME/bin:$PATH
```
Set the DITA_HOME environment variable to point to the DITA-OT installation directory.
```
export DITA_HOME=<DITA-OT_dir>
```

Set up the CLASSPATH environment variable.

export CLASSPATH=$DITA_HOME/lib/dost.jar:$CLASSPATH
export CLASSPATH=$DITA_HOME/lib:$CLASSPATH
export CLASSPATH=$DITA_HOME/lib/resolver.jar:$CLASSPATH
export CLASSPATH=$DITA_HOME/lib/commons-codec-1.4.jar:$CLASSPATH

Optional: If you use Ant, version 1.8 or later, set up the CLASSPATH environment variable to include Apache Xerces.
```
export CLASSPATH=<xerces_dir>/xercesImpl.jar:<xerces_dir>/xml-apis.jar:$CLASSPATH
```

Set up the XSLT processor:

Processor	Action
Saxon	Set up the `CLASSPATH` environment variable to include the Saxon JAR files, for example: export CLASSPATH=<saxon_dir>/saxon9.jar:<saxon_dir>/saxon9-dom.jar:$CLASSPATH Set up the `ANT_OPTS` environment variable, for example: export ANT_OPTS=$ANT_OPTS -Djavax.xml.transform.TransformerFactory=net.sf.saxon.TransformerFactoryImpl
Xalan	Set up the `CLASSPATH` environment variable to include the Xalan JAR files, for example: export CLASSPATH=<xalan_dir>/xalan.jar:$CLASSPATH

Optional: For index processing, set up ICU for Java.
```
export CLASSPATH=<icu4j_dir>/icu4j.jar:$CLASSPATH
```
Optional: For JavaHelp, set the JHHOME environment variable.
```
export JHHOME=<javahelp_dir>
```

Optional: For PDF output, set up the XSL-FO processor:

Processor	Action
FOP	Add the FOP installation directory to the local.properties file as the fop.home property, for example: fop.home=/usr/share/java/fop
RenderX	Add the RenderX installation directory to the local.properties file as the xep.dir property, for example: xep.dir=/usr/share/java/xep
Antenna House	Add the AH Formatter installation directory to the local.properties file as the axf.path property, for example: axf.path=/usr/share/java/AHFormatterV6

Test the DITA-OT installation by transforming the sample files.
The samples\ant_sample directory contains Ant scripts designed to build various output formats.
```
/usr/local/share/DITA-OT1.8.5$ ant -f samples/ant_sample/sample_all.xml
```
The generated output is written to the DITA-dir\out\samples directory. The following output formats are generated:
- Docbook
- Eclipse help
- HTML Help
- ODT
- JavaHelp
- PDF
- TocJS
- TROFF
- XHTML
