After checking out from the repository, here's how to build.
All other dependencies are included in the repository.
Set the JAVA_HOME environment variable to point to the directory where the JDK is installed. For example, on Linux do something like
export JAVA_HOME=/opt/jdk1.6.0_10
and, on Windows, do something like
set JAVA_HOME=c:\Program Files\Java\jdk1.6.0_10
Change your working directory to be root source directory (i.e. the directory containing this file).
Run the ant script included in the repository. On Linux, use the command
./ant
On Windows, use
.\ant
This runs the version of ant included in the repository. When the ant script completes, you should find jing.jar and trang.jar in the build directory.
You can also tell ant to build the test target, which will build the jars and then run some tests. On Linux,
use the command
./ant test
On Windows, use
.\ant test
