Development Info

Dependencies

Compilation instructions (ANT command-line)

Setup the XOWA app

• Download the latest XOWA app package for your operating system. For example, if you're on a 64-bit Linux system, "xowa_app_linux_64_v1.9.5.1.zip".
• Unzip the XOWA app package to a directory. For the sake of simplicity, these instructions assume this directory is "/xowa/"
• Review your directories. You should have the following:
  • An XOWA jar: "/xowa/xowa_linux_64.jar"
  • An XOWA "/bin/any/" directory with several jar files. For example, "/xowa/bin/any/java/apache/commons-compress-1.5.jar"
  • An XOWA "/bin/linux_64/" directory with an SWT jar: "/xowa/bin/linux_64/swt/swt.jar"

Setup the XOWA source

• Download the latest XOWA source archive. For example: "xowa_source_v1.9.5.1.7z"
• Unzip the source to "/xowa/dev". When you're done, you'll have a file called "/xowa/dev/build.xml" as well as others
  • NOTE: if you're not on a Linux 64-bit system, overwrite the swt jar at "/xowa/dev/150_gfui/lib/swt.jar" with the copy from your "/bin/OS" directory. For example, if you're on a 64 bit Windows system, replace "/xowa/dev/150_gfui/lib/swt.jar" with "/bin/windows_64/swt/swt.jar"

Run the ant file

• Open up a console, and run "ant -buildfile build.xml -Dplat_name=linux_64"
