This section covers various development tools and features.
This release of Fedora has been built with GCC 4.1, which is included with the distribution.
This release of Fedora includes Fedora Eclipse, based on the Eclipse SDK version 3.2.2 (http://www.eclipse.org). The "New and Noteworthy" page for the 3.2.x series of releases can be accessed at http://download.eclipse.org/eclipse/downloads/drops/R-3.2-200606291905/new_noteworthy/eclipse-news.html. Release notes specific to 3.2.2 are available at http://www.eclipse.org/eclipse/development/readme_eclipse_3.2.2.html.
The Eclipse SDK is known variously as "the Eclipse Platform," "the Eclipse IDE," and "Eclipse." The Eclipse SDK is the foundation for the combined release of ten Eclipse projects under the Callisto combined release umbrella (http://www.eclipse.org/callisto). A few of these Callisto projects are included in Fedora: CDT (http://www.eclipse.org/cdt, for C/C++ development, EMF (http://www.eclipse.org/emf) the Eclipse Modeling Framework, and GEF (http://www.eclipse.org/gef), the Graphical Editing Framework.
Many third-party Eclipse projects are also available, including Subclipse (http://subclipse.tigris.org/) for integrating Subversion version control, PyDev (http://pydev.sf.net) for developing in Python, and PHPeclipse (http://www.phpeclipse.de/) for developing in PHP. Mylar (http://eclipse.org/mylar), a task-focused UI for Eclipse, is also available in Fedora with task connectors for Bugzilla and Trac. It was not part of Callisto but will be part of the forthcoming Europa combined Eclipse release.
Assistance in getting more projects packaged and tested with GCJ is always welcome. Contact the interested parties through fedora-devel-java-list (http://www.redhat.com/mailman/listinfo/fedora-devel-java-list/) and/or #fedora-java on freenode.
Fedora also includes plugins and features that are particularly useful to FLOSS hackers, ChangeLog editing with eclipse-changelog, and Bugzilla interaction with eclipse-mylar-bugzilla. Our CDT package also includes the work-in-progress GNU Autotools plugin. This plugin allows end-users to use Eclipse to build and maintain C/C++ projects that use GNU autotools. Enhancements to the CDT include:
Performing configuration prior to build
Special editors for autoconf/automake input files
Special help for autoconf macros
Hover help for C library functions
A special console for configuration
The latest information regarding these projects can be found at the Fedora Eclipse Project page: http://sourceware.org/eclipse/.
This release includes 21 language packs for the Eclipse SDK. Each language is packed into a separate package, such as eclipse-sdk-nls-ko for the Korean translation.
Fedora Eclipse contains a patch to allow non-root users to make use of the
Update Manager functionality for installing non-packaged
plugins and features. Such plugins are installed in the user's
home directory under the .eclipse directory.
Please note, however, that these plugins do not have
associated GCJ-compiled bits and may therefore run slower than
expected.
The Fedora free JRE does not satisfy every user, so Fedora does allow the installation of alternative JREs. A caveat exists, however, for installing proprietary JREs on 64-bit machines.
The 64-bit JNI libraries shipped by default on x86_64 systems in Fedora do not run on 32-bit proprietary JREs. In other words, do not try to run Fedora's x86_64 Eclipse packages on Sun's 32-bit JRE. They fail in confusing ways. Either switch to a 64-bit proprietary JRE, or install the 32-bit version of the packages, if available. To install a 32-bit version, use the following command:
yum install <package_name>.i386
Likewise, the 32-bit JNI libraries shipped by default on ppc64 systems do not run with a 64-bit JRE. To install the 64-bit version, use the following command:
yum install <package_name>.ppc64
In June 2007, the Eclipse community is releasing the Europa combined release of an assortment of plugins and features. This will be based on and include version 3.3 of the Eclipse SDK. This is a major change and because of that, Fedora Eclipse is not going to be re-basing on Europa until Fedora 8. This means that versions of Eclipse-based applications included in Fedora such as RSSOwl and Azureus may lag upstream releases if they require features only available in Eclipse 3.3.
