Qt 4 is a comprehensive, object-oriented development framework that
|
|
enables development of high-performance, cross-platform rich-client
|
|
and server-side applications. When you implement a program with Qt,
|
|
you can run it on the X Window System (Unix/X11), Apple Mac OS X, and
|
|
Microsoft Windows NT/9x/2000/XP by simply compiling the source code for
|
|
the platform you want. 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).
|
|
|
|
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 :-)
