EduMIPS64 is a cross-platform visual MIPS64 CPU simulator written in Java/swing.

The EduMIPS64 web site is http://www.edumips.org. There is also a developers' blog at http://edumips64.blogspot.com.

To learn how it works and how to use it, please refer to the EduMIPS64 User Manual (in the docs/{en,it}/output/latex directory). This file is a short guide for developers who are interested in compiling the simulator from scratch and/or modifying its source code.

The JAR for the latest development version is available at http://lupino3.github.io/edumips64/edumips64-latest.jar (built by Travis CI every time a new revision is pushed).

In order to compile EduMIPS64, you need the following tools:

• Java JDK version 7 or above.
• Apache Ant version 1.8 or above (needed for JUnit 4 tests)
• Sphinx (http://sphinx.pocoo.org/) versione 1.0.7 or above
• GNU Make
• JavaHelp

The latter three dependencies are needed for the in-application help.

If you need to compile the PDF manual, you will also need:

• latex / pdflatex

If you want to use the automatic style checks (pre-commit hook), then you should have Automatic Style (astyle) installed.

A distribution of JUnit 4 and JavaHelp is included in the libs/ directory of the git reposiory, but not in the source tarball.

This project uses Travis CI for continuous integration (https://travis-ci.org/lupino3/edumips64).

• standalone-jar builds the jar package named edumips64-version.jar, that embeds the JavaHelp libraries, and is oriented towards users downloading the JAR archive from the website (not through package managers).

• slim-jar builds the jar package named edumips64-version-nodeps.jar, that does not embed the JavaHelp libraries and is oriented towards distribution package creators, that should add a dependency on JavaHelp and appropriately set the classpath in their scripts.

• docs builds the user documentation (both in-app HTML and PDF)

• clean removes the jar files, the build directory and the compiled documentation

• test runs unit tests;

• cli-jar build a jar package containing an experimental CLI front-end

• src-release builds a tar.bz2 file containing the source distribution

• javadoc builds the javadoc documentation; will store it in the javadoc directory.

Any ant target that requires the compilation of the source code (i.e., creation of application JARs or running unit tests) require that the JavaHelp jar is in the CLASSPATH; in addition to this, running unit tests and building the javadoc require the JUnit 4 jar to be in the classpath. Example::

CLASSPATH=/usr/share/java/jhall.jar ant CLASSPATH=/usr/share/java/junit4.jar:/usr/share/java/jhall.jar ant test CLASSPATH=/usr/share/java/junit4.jar:/usr/share/java/jhall.jar ant javadoc

Set those variables to modify some compile-time options:

• src_java_version (default: 7): Java version of source code;

• dst_java_version (default: 7): bytecode target version;

• debug (default: on): whether to compile with debugging info;

To set any variable, use the -D option of ant.
