This section covers various development tools and features.
14.1. Tools
14.1.1. GCC Compiler Collection
This release of Fedora has been built with GCC 4.3.0, which is included with the distribution.
For more information on GCC 4.3, refer to:
14.1.1.1. Code Generation
Starting with gcc-4.1.2-25 and
glibc-2.6.90-14 , the
-D_FORTIFY_SOURCE=2 option protects not only
C code, but also C++. There have been several security issues
already which would not have been exploitable if this checking
was in place earlier. Refer to this
announcement:
https://www.redhat.com/archives/fedora-devel-announce/2007-September/msg00015.html for more details.
14.1.2. Eclipse
This release of Fedora includes Fedora Eclipse, based on the Eclipse SDK version 3.3.2. You can read the "New and Noteworthy" page for the 3.3.x series of releases can be accessed at:
http://download.eclipse.org/eclipse/downloads/drops/R-3.3-2007-06251500/whatsnew/eclipse-news.html
Release notes specific to 3.3.2 are available at:
http://www.eclipse.org/eclipse/development/readme_eclipse_3.3.2.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 twenty-one Eclipse projects under the Callisto combined release umbrella:
A few of these Europa projects are included in Fedora:
-
CDT for C/C++ development:
-
GEF, the Graphical Editing Framework:
-
Mylyn, a task-focused UI for Eclipse, along with task connectors for Bugzilla and Trac:
Other Eclipse projects available in Fedora include:
-
Subclipse, for integrating Subversion version control:
-
PyDev, for developing in Python:
-
PHPeclipse, for developing in PHP:
Assistance in getting more projects packaged and tested with GCJ is always welcome. Contact the interested parties through fedora-devel-java-list and/or #fedora-java on freenode:
http://www.redhat.com/mailman/listinfo/fedora-devel-java-list/
Fedora also includes plugins and features that are particularly useful to FLOSS hackers, ChangeLog editing with eclipse-changelog , and Bugzilla interaction with eclipse-mylyn-bugzilla . Our CDT package, eclipse-cdt , includes a snapshot release of work to integrate with the GNU Autotools.
The latest information regarding these projects can be found at the Fedora Eclipse Project page:

14.1.2.1. Non-packaged Plugins/Features
Fedora Eclipse allows
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.
14.1.2.2. Alternative Java Runtime Environments
The Fedora free JREs do 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 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
