Install Ubuntu 12.04 (32bit version) and add the package listed below.

Code>

Compile JavaRock Samples

Set PATH, which defines the location of javarock_20130708.jar is placed, to the environment variable of JavaRock, JAVAROCK.

Code>

Compile samples/pong. Assume that the directory of samples is /home/beat/JavaRock/samples. If comile_fpga.sh does not have the executable permission, give it, and execute it.

Code> After the compile process is completed, please check that class files and vhd file are generated.
