Getting Started/Build/KDE4.1

    From KDE TechBase

    Objectives

    You probably want to keep your current KDE-3.5.x installation till you feel that KDE-4.x.y meets your needs for actual day to day use of your computer. Yet, you want to be able to change over with a minimum of work when the time comes to make the switch.

    Method

    The best way to accomplish this is to install the needed support libraries on your system in the usual manner. Convention is that these should be installed in the /usr/local/ directory. By default, Troll Tech installs Qt in: /usr/local/Trolltech/Qt-4/. The current KDE-4.0 release branch should be built against Qt-4.3.x (the latest in this branch is 4.3.3 which should be used unless there are reasons not to use it). It is best to install KDE-4.x.y in its own directory so that the directory can be deleted if some large problem occurs. I will be using /usr/local/KDE-4.0/ but you can call it whatever you want.

    We will keep configurations straight by using a separate user account for accessing KDE-4.x.y. This user account will contain your configurations of KDE-4 and will have a script to set the environment variables (.bash_profile if using Linux).

    Installation

    Required packages from your distribution

    See requirements for TRUNK

    Create the User Account

    Use whatever method you wish to create a new user account. Mine is called: "KDE4". Then edit or create the user specific login script (.bash_profile for Linux). There is a lot that goes into this. Note that this presumes that USER was correctly set by the system login script.

    This is in addition to other things that you need in the script which would probably go at the beginning -- this large block of junk is to be added at the end. The XDG directories might need to be modified for your system.

    To build, you must be logged on as the new user account (KDE4). You can 'su' for the whole thing or 'su -C' for each install.

    Qt is configured with --prefix=/usr/local/Trolltech/Qt-4.
    KDE should use: -DCMAKE_INSTALL_PREFIX=/usr/local/KDE-4 when running cmake.
    Other packages should be installed with the default prefix (/usr/local).
