KDE 3.5 Compilation Requirements

Compilers

Compiler Requirements. KDE is designed to be portable and hence to compile with a large variety of GNU/Linux and UNIX compilers. However, KDE is advancing very rapidly and the ability of native compilers on various UNIX systems to compile KDE depends on users of those systems reporting compile problems to the responsible developers.

In addition, the C++ implementation in gcc/egcs, the most popular KDE compiler, has been advancing rapidly, and has also recently undergone a major redesign. As a result, KDE will not compile properly with older versions of gcc or most newer releases.

In particular, gcc versions earlier than gcc-2.95, such as egcs-1.1.2 or gcc-2.7.2, may not properly compile some components of KDE 3.5. While there have been reports of successful KDE compilations with the so-called gcc-2.96 and gcc-3.4 (cvs), the KDE project at this time recommends the use of gcc-3.3.1 or a version of gcc which shipped with a stable Linux distribution and which was used successfully to compile a stable KDE for that distribution.

Nearly all KDE applications benefit from alpha blended icons and anti-aliased fonts. kdelibs, kdebase, kdeaddons, kdeadmin, kdeartwork, kdebindings, kdeedu, kdegames, kdegraphics, kdemultimedia, kdenetwork, kdepim, kdesdk, kdetoys, kdeutils, koffice, kdevelop
X Fixes Extension Optional The X Fixes extension was created to address a number of shortcomings in the core X window system that prevented applications from doing some things efficiently. The X Fixes extension is available in version 6.8 or later of X.org. Klipper benefits from the XFixes extension, in the form of reduced CPU utilization in both Klipper and the X server. This extension is also needed by applications that use the Composite and Damage extensions. kdebase
X Composite Extension Optional The X Composite extension adds support for translucent windows and non-rectangular windows with anti-aliased edges to the X window system. It also makes the content of obscured windows available to for example desktop pagers, and provides backing store which eliminates flicker. It also makes it possible for a composition manager to draw dynamic effects on the screen, such as window drop shadows. The X Composite Extension is available in version 6.8 or later of X.org. All KDE applications benefit from reduced flicker, and effects drawn by the composition manager. Kicker uses the composite extension for creating thumbnails of windows and displaying them in the pager. kdebase
