KDE 4.2 Compilation Requirements -- intended to be a comprehensive list of all external software needed to build a full-featured KDE 4.2.

Compilers

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

In addition, the C++ implementation in gcc, 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 their newest unreleased version.

Help

Package	Level	Description	Explanation	Modules
libxml2 >= 2.4.8	Recommended	Libxml provides an XML parser and toolkit. XML is a metalanguage to design markup languages, such as HTML.	Libxml is used for reading KDE documentation. Note that even though earlier versions of libxml2 may work, versions 2.4.26 through 2.4.28 have a bug which prevents their use in KDE.	kdelibs, kdepimlibs, kdebase, kdeadmin, kdeartwork, kdebindings, kdeedu, kdegames, kdegraphics, kdemultimedia, kdenetwork, kdepim, kdesdk, kdetoys, kdeutils, koffice, kdevelop

Hardware

Package	Level	Description	Explanation	Modules

Browsing

Package	Level	Description	Explanation	Modules
Java >= 1.3	Recommended	Java is a programming language designed for use in the distributed environment of the Internet. Since Netscape integrated Java into its browser, Java has become a popular language for websites.	Some websites require the use of Java for some or all of their services. In addition, Java bindings exist for KDE which enables writing KDE applications in the Java language.	kdebase, kdebindings
