Qt is the basis for the KDE desktop environment, +and is also used in numerous commercial applications. This Qt 4 package is created to enable co-existence with Slackware native Qt 3 package; developers should only remember to use versions with "-qt4" suffix (like "qmake-qt4", "assistant-qt4", "designer-qt4", etc.) of programs that exist under same names in Qt 3 (and developers -using CMake should be fine without any additional action, because -stock CMake is already looking for "qmake-qt4" first). +using CMake should be fine without any additional action, because stock +CMake is already looking for "qmake-qt4" first). + +Qt 4.5 comes with a new graphicssystem backend named "raster" which +outperforms the current standard one, but is not yet set as standard +because it might not work with all Qt4 applications out there currently. +You can set it as standard by passing RASTER=yes to the script. +Alternatively you can also set it on runtime for each application (if you +start it from the command line). Tests have shown that "normal" Qt4 apps +work well with it, whereas KDE 4.2 does not. + +Further you can enable the patches kde has included in its qt-copy +tree by passing QTCOPY=yes to the script. This fixes some issues which +make Qt apps nicer to use in kde(4). Descriptions of the individual +patches are available in the respective diff or patch files. If you +want to additionally *not* build with support for Phonon (as does qt in +Slackware-current at the moment), you can pass PHONON=no to the script. + +WARNING: This requires *a lot* of harddisk space available on build time. +Be sure to have at least 2GB of free diskspace. + +WARNING: Do not use upgradepkg to to upgrade from qt4-4.4.3 or earlier. +You should remove the old one and use installpkg for qt4 >= 4.5.0 in +that case. If you (accidentally or otherwise) ignore this advice, you +can safely remove any broken links in / and rm -rf /usr/lib/qt-4.4.3 +afterward :-) |
