JavaRock is a high-level synthesis language, which generates HDL from Java language.~
This article shows how to set up the basic working environment for JavaRock.~
* How to Compile a JavaRock sample on Ubuntu (12.04 32bit version) [#obbde32b]
** Basic set up [#xbf69616]
>
The newest compiled JavaRock is javarock_20130708.jar, and the latest sample code set of JavaRock is samples_20130707.tar,gz.~
Please download them from the URL shown below.~
[[http://sourceforge.net/projects/javarock/files/20130708/]]
>
Install Ubuntu 12.04 (32bit version) and add the package listed below.
$ sudo apt-get install build-essential
$ sudo apt-get install openjdk-7-jdk
** Compile JavaRock Samples [#j2911306]
>
Set PATH, which defines the location of javarock_20130708.jar is placed, to the environment variable of JavaRock, JAVAROCK.
$ export JAVAROCK=/home/beat/JavaRock/javarock_20130708.jar
~
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.~
$ cd JavaRock/
$ ls

* How to Compile JavaRock sample on Mac OS X [#m8f0256a]
>
JavaRock can be compiled on Mac OS X Mavericks (10.9.3) if JDK7 is installed to Mac OS X.~
The default Java on Mac OS X Mavericks is Java 1.6, but JavaRock cannot be compiled with Java 1.6. Java 1.7 is the requirement.~
~

After the download of jdk-7u55-maxosx-x64.dmg is completed, the execute the file.~
As the installer screen shows up, please follow its instructions to install JDK.~
After the installation is completed, please check its version of JDK.~

** Compile JavaRock samples [#h615f7a0]
>
Confirming that JDK7 is installed, set PATH, which defines the location of javarock_20130708.jar is placed, to the environment variable of JavaRock, JAVAROCK. This is the same way as having done to Ubuntu.~
$ export JAVAROCK=/home/beat/JavaRock/javarock_20130708.jar
Setting PATH to the environment variable, execute samples/test/test.sh.~
$ cd ~/JavaRock/samples/test
$ ./test.sh
Compile: counter
Compile: led
Compile: SC1602Wrapper
Compile: SC1602Writer
Compile: sc1602_test
Compile: echo

If the class file and vhd file exist, this file, test.sh, is executed correctly,~
If test.sh is executed without updating the version of Java, these errors will occur. The details are shown below.~

$ cd ~/JavaRock/samples/test
$ ./test.sh
An exception has occurred in the compiler ((version info not available)). Please file a bug at the JavaRock BugTracks (http://sourceforge.net/p/javarock/bugs/) after checking the Bug Parade for duplicates.
