1. Get CableLabs known working cygwin install: cygwin-minimal-20120803.zip
2. Install cygwin from local directory, using the CableLabs known working cygwin. See Build Environment - Cygwin MinGW. 
3. Download and install appropriate JDK: http://www.oracle.com/technetwork/java/javase/downloads/index.html.  See "Windows Build Tools" section of Build Environment - Cygwin MinGW.
4. Download and install appropriate Ant (version 1.8.1 or later is required): http://ant.apache.org/bindownload.cgi.  See "Windows Build Tools" section of Build Environment - Cygwin MinGW.
5. Add the paths to the JDK and Ant to your path, e.g. export PATH=$PATH:/cygdrive/c/apache-ant-1.8.1/bin:/cygdrive/c/Java/jdk1.6.0_20/bin). 
6. Checkout source from repository.  In an appropriate sub-directory:

> svn checkout -N https://community.cablelabs.com/svn/OCAPRI
>  cd OCAPRI
> ./checkout_dev_env.sh trunk

...

1. Build the platform (the support code for the OCAP stack).  Start a new terminal session to pick up the environment changes you just made
   

   Code Block
   > cd $PLATFORMROOT > make clean purge build

2. Build the OCAP stack (the Java VM and support libraries):

   Code Block
   > cd $OCAPROOT > ant clean purge build

   From this point forward, 'ant purge' should work.  You can do a super-clean build using 'ant clean purge build'.

See Building Overview for additional information.

Running the RI

Before running the RI you may need to make some configuration changes:

• It is very likely that you will need to disable any firewall on your development machine as the RI uses various ports and processes to handle streaming, etc.
• Depending on your particular video hardware/driver configurationit is likely that you will need to turn off hardware acceleration for your display.
  
  • (Control Panel->Display->Settings-> Advanced->Troubleshoot (Windows XP)

Run the RI:

1. Run the RI with the TuneTest xlet to verify that the RI is installed and functioning as expected.

> cd $PLATFORMROOT;
> ./runRI.sh -tunetest -setup

Note: on On a fresh checkout or binary install the initial tune test failsmay fail. If this occurs Ctrl-C ( to stop the RI ) and repeat "./runRI.sh -tunetest : the initial ".  The tune should now work.  For more information on TuneTest please see Running Tune Test.

Another Note: If you have not run vlc on your machine you may need to run it interactively in order to answer an interactive prompt. To do so:

> cd <wherever you installed it ocap-r>i/trunk/common/resources/Win32/VLC
> ./vlc.exe

vlc will start interactively (you may need to find the window). After you have closed the window vlc will start without the prompt.

So... now what?

To get your Xlet running with the RI, look at $OCAPROOT/bin/$OCAPTC/env/hostapp.properties.

There is also a wealth of QA

...

Integration Xlets available (some may not work at the moment - YMMV). See Running QA Apps on the RI

...

 and Integration Xlet Testing for more information.
