FOR IMMEDIATE RELEASE
Free KDE Desktop Ready for Enterprise Deployment
KDE Ships Leading Desktop with Advanced Web Browser and Development Environment for Linux and Other UNIXes
August 15, 2001 (The INTERNET). The KDE Project today announced the immediate release of KDE 2.2, a powerful and easy-to-use Internet-enabled desktop for Linux. Consistent with KDE's rapid and disciplined development pace, the release of KDE 2.2 features an impressive catalog of speed/performance enhancements, feature additions and stability improvements. KDE 2.2 is available in 34 languages and ships with the core KDE libraries, the core desktop environment, and over 100 applications from the other base KDE packages (administration, multimedia, network, PIM, development, etc.).
"The productivity tools and interface improvements in the new KDE desktop provide a powerful client environment," said Kent Ferson, vice president of Compaq's Tru64 UNIX Systems Division. "We're pleased to offer KDE 2.2 on Tru64 UNIX and to enhance our Linux-Tru64 UNIX affinity capabilities for interoperability and application mobility. Compaq acknowledges Dr. Tom Leitner of Graz University of Technology and the KDE development team for their support in delivering this affinity capability."
KDE 2.2 will be complemented later this month by the stable release of KOffice 1.1, a comprehensive, modular, component-based suite of office productivity applications. This combination is the first to provide a complete Open Source desktop and productivity environment for Linux/Unix.
"Thanks to the high quality of the KDE 2 development framework and the invaluable feedback of our users we are delivering a more polished, better integrated and more feature-rich desktop experience in a relative short time. With the pending release of a stable KOffice this month, KDE offers a complete high-quality desktop and development platform without the costs and restrictions associated with proprietary desktops," said Waldo Bastian, release manager for KDE 2.2 and a SuSE Labs developer.
Dave Richards, the System Administrator for The City of Largo, Florida who recently spearheaded the successful roll-out of KDE on 400 thin clients serving 800 users in City offices, explained why the City selected KDE and Linux: "All city terminals log into one big 'desktop' system to get the KDE desktop. Since uptime of this server is so critical, we picked Linux. KDE gave us an excellent presentation layer with which to run all of the City applications that are running on other servers (both Unix and Windows)."
"It is important for enterprises to realize that the huge cost savings they can obtain immediately upon conversion to KDE do not require any sacrifice in terms of software available to their users," added Andreas Pour, Chairman of the KDE League. "The capabilities of Konqueror, the expansive array of free software available for KDE/Qt and the large number of other Open Source projects will solve most if not all problems natively. For those applications only available for Windows at this juncture, several alternative products, both commercial and Open Source, exist: running Windows terminal sessions in KDE, running Windows applications natively under KDE/Linux, and providing remote desktop sessions. There is no reason companies cannot today shed themselves of at least a substantial portion of wasteful licensing fees for their desktop users."
In addition, KDE offers seamless network transparency for accessing or browsing files on Linux, NFS shares, MS Windows SMB shares, HTTP pages, FTP directories, LDAP directories, digital cameras and audio CDs. The modular, plug-in nature of KDE's file architecture makes it simple to add additional protocols (such as IPX or WebDAV) to KDE, which would then automatically be available to all KDE applications.
Besides the exceptional compliance with Internet and file-sharing standards mentioned above, KDE 2 is a leader in compliance with the available Linux desktop standards. KWin, KDE's new re-engineered window manager, complies to the new Window Manager Specification. Konqueror and KDE comply with the Desktop Entry Standard. Konqueror uses the XBEL standard for its bookmarks. KDE 2 largely complies with the X Drag-and-Drop (XDND) protocol as well as with the X11R6 session management protocol (XSMP).
The KDE 2.2 release features a number of enhancements which remove any potential obstacles to widespread, productive enterprise adoption of the free KDE desktop:
KDE 2: The K Development Environment. KDE 2.2 offers developers a sophisticated IDE as well as a rich set of major technological improvements over the critically acclaimed KDE 1 series. Chief among the technologies are the Desktop COmmunication Protocol (DCOP), the I/O libraries (KIO), the component object model (KParts), an XML-based GUI class, and a standards-compliant HTML rendering engine (KHTML).
KDevelop is a leading Linux IDE with numerous features for rapid application development, including a GUI dialog builder, integrated debugging, project management, documentation and translation facilities, built-in concurrent development support, and much more. This release includes a number of new features, including a setup wizard, code navigation, a console, man page support and colored text, as well as a number of new project templates, including KControl modules, Kicker (panel) applets, kio-slaves, Konqueror plugins and desktop themes.
KParts, KDE 2's proven component object model, handles all aspects of application embedding, such as positioning toolbars and inserting the proper menus when the embedded component is activated or deactivated. KParts can also interface with the KIO trader to locate available handlers for specific mimetypes or services/protocols. This technology is used extensively by the KOffice suite and Konqueror.
KIO implements application I/O in a separate process to enable a non-blocking GUI without the use of threads. The class is network and protocol transparent and hence can be used seamlessly to access HTTP, FTP, POP, IMAP, NFS, SMB, LDAP and local files. Moreover, its modular and extensible design permits developers to "drop in" additional protocols, such as WebDAV, which will then automatically be available to all KDE applications. KIO also implements a trader which can locate handlers for specified mimetypes; these handlers can then be embedded within the requesting application using the KParts technology.
DCOP is a client-to-client communications protocol intermediated by a server over the standard X11 ICE library. The protocol supports both message passing and remote procedure calls using an XML-RPC to DCOP "gateway". Bindings for C, C++ and Python, as well as experimental Java bindings, are available.
KDE also provides a number of language bindings. In particular, KDE kdejava provides full Java bindings for KDE and Qt, which look and behave identically to a C++ version, including access to the C++ signals/slots.
Installing Binary Packages
Binary Packages. All major Linux distributors and some Unix distributors have provided binary packages of KDE 2.2 for recent versions of their distribution. Some of these binary packages are available for free download under http://master.kde.org/pub/kde/stable/2.2/ or under the equivalent directory at one of the many KDE ftp server mirrors. Please note that the KDE team is not responsible for these packages as they are provided by third parties -- typically, but not always, the distributor of the relevant distribution (if you cannot find a binary package for your distribution, please read the KDE Binary Package Policy).
Library Requirements. The library requirements for a particular binary package vary with the system on which the package was compiled. Please bear in mind that some binary packages may require a newer version of Qt and other libraries than was included with the applicable distribution (e.g., LinuxDistro 8.0 may have shipped with qt-2.2.3 but the packages below may require qt-2.3.x). For general library requirements for KDE, please see the text at Source Code - Library Requirements below.
Package Locations. At the time of this release, pre-compiled packages are available for:
Downloading and Compiling KDE 2.2
Library Requirements. KDE 2.2 requires qt-2.2.4, which is available in source code from Trolltech as qt-x11-2.2.4.tar.gz. In addition, for SSL support, KDE 2.2 requires OpenSSL >= 0.9.6x; versions 0.9.5x are no longer supported. For Java support, KDE 2.2 requires a JVM >= 1.3. For Netscape plugin support, KDE requires a recent version of Lesstif or Motif. Searching local documentation requires htdig. Other special features, such as drag'n'drop audio CD ripping, require other packages.
Compiler Requirements. Please note that some components of KDE 2.2 will not compile with older versions of gcc/egcs, such as egcs-1.1.2 or gcc-2.7.2. At a minimum gcc-2.95-* is required. In addition, some components of KDE 2.2 (such as the multimedia backbone of KDE, aRts) will not compile with gcc 3.0 (the problems are being corrected by the KDE and GCC teams).
Source Code/RPMs. The complete source code for KDE 2.2 is available for free download at http://master.kde.org/pub/kde/stable/2.2/src/ or in the equivalent directory at one of the many KDE ftp server mirrors. Additionally, source rpms are available for the following distributions:
