This section covers various development tools and features.

14.1. Alati

14.1.1. GCC zbirka sastavljača

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:

http://gcc.gnu.org/gcc-4.3/

14.1.1.1. Generiranje koda

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 3.3.0. 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 3.3.0 are available at:

http://www.eclipse.org/eclipse/development/readme_eclipse_3.3.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:

http://www.eclipse.org/europa

A few of these Europa projects are included in Fedora:

CDT for C/C++ development:

http://www.eclipse.org/cdt
GEF, the Graphical Editing Framework:

http://www.eclipse.org/gef
Mylyn, a task-focused UI for Eclipse, along with task connectors for Bugzilla and Trac:

http://www.eclipse.org/mylyn

Other Eclipse projects available in Fedora include:

Subclipse, for integrating Subversion version control:

http://subclipse.tigris.org/
PyDev, for developing in Python:

http://pydev.sf.net
PHPeclipse, for developing in PHP:

http://www.phpeclipse.de/

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

14.2. KDE 4 Development Platform

Fedora 9 includes KDE 4.0 (beta) development libraries. The following new packages are provided:

kdelibs4 : KDE 4 libraries
kdepimlibs : KDE 4 PIM libraries
kdebase4 : KDE 4 core runtime files

Use these packages to develop, build and run KDE 4 applications within KDE 3 or any other desktop environment.

The kdebase4 package also includes a beta version of the Dolphin file manager as a technology preview. As this is a beta version, some issues may still be present. If you need a stable version of Dolphin, please install the d3lphin package, which is based on KDE 3 and can be safely installed alongside kdebase4 .

These packages are designed to:

comply with the Filesystem Hierarchy Standard (FHS), and
be completely safe to install in parallel with KDE 3, including the -devel packages.

In order to achieve this, Fedora KDE SIG members made 2 changes to the -devel packages:

The library symlinks are installed to /usr/lib/kde4/devel or /usr/lib64/kde4/devel, depending on system architecture.
The kconfig_compiler and makekdewidgets tools have been renamed kconfig_compiler4 and makekdewidgets4, respectively.

These changes should be completely transparent to the vast majority of KDE 4 applications that use cmake to build, since FindKDE4Internal.cmake has been patched to match these changes.

Note that kdebase4 does not include the KDE 4 Desktop package kdebase-workspace and its components such as Plasma and KWin version 4. The kdebase-workspace package is still too incomplete and unstable for daily use and would conflict with KDE 3.
