Release Notes

Installation

Prerequisites

JunC++ion/JuggerNET v4 is significantly different from JunC++ion/JuggerNET v3. The old version of the code generator used to bundle a Java Runtime Environment (on some platforms but not on others) and you had to download different install packages for different operating systems.

JunC++ion/JuggerNET v4 does not bundle a JRE anymore and there is one download for all platforms. We recommend that you install a JDK 1.6 or higher before running JunC++ion v4 for the first time.

Download Code Generator

Download the code generator bundle as a platform-independent tar.gz file for all operating systems and processor architectures.

Unpack

Unpack the archive into a directory of your choice. The archive contains a top-level directory named junc++ion-<major.minor.patch>. Don't be confused by the name if you are interested in JuggerNET: the package contains everything you need.

Download Runtime Library

JunC++ion/JuggerNET v4 does not include operating system- and compiler-specific runtime libraries anymore. We decided to exclude operating system-specific components from the code generator download package. Instead, you can now download the desired operating system-specific components from within the code generator, thereby greatly reducing duplicative and unnecessary downloads.

You need to download at least one runtime library from Codemesh's website before you can successfully link any examples or generated code.

If you run the code generator GUI and it cannot locate your host's operating system-specific runtime library in a subdirectory of the cpp/v3 directory, you will be asked whether you wish to download it. Please make sure that you

  • know your Codemesh download credentials, and
  • have the necessary privileges to modify the code generator's nested cpp/v3 directory.

Alternatively to using the GUI version, you can use the commandline version, for example if you are working in console-only mode. Simply change into the code generator's bin directory and instruct the code generator to download a runtime via:

[alex@z3000] ./xmog -download
[alex@z3000]

Assuming you had the required file system privileges and the download succeeded, you will now have a proper runtime library for your operating system.

Please note that you can download runtime libraries at a later point too. The code generator GUI contains a menu option that allows you to download runtime libraries for any supported operating system.

Enhancements

The v4 release has a lot of new features and feature enhancements. They include:

  • brand-new, completely redesigned code generator GUI.
  • completely terp®-based, allowing powerful expressions in all commands.
  • powerful selection expressions for types, methods, and fields.
  • template-based code generation, allowing for extensive code customization by user.
  • ability to add more templates to code generation.
  • modelfiles can reference other modelfiles for dependent projects.
  • configurable name transformations.
  • brand-new tutorial.
  • generates ANT projects for flexible builds.

Limitations

This is still pre-release software, so there are a few areas where JunC++ion v4 does not yet implement a feature that is present in JunC++ion v3. These limitations include:

  • class callbacks.
    JunC++ion v4 currently only supports interface callbacks.
  • remote JVM.
    The remote JVM server has not yet been added to the build.
  • AIX support.
    We currently don't have an AIX build machine in-house, so there is no AIX runtime.
  • makefiles.
    Makefiles are not yet being generated. Use ANT scripts if possible.
  • HTML doc.
    The generated HTML documentation is not yet complete.
