One of the major users of Qt is KDE. &lfs77_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &qt4-md5sum; Download size: &qt4-size; Estimated disk space required: &qt4-buildsize; Estimated build time: &qt4-time; Qt Dependencies Required Recommended , , , , , (unicode support), , , , , , and Optional , (GTK+ 2 theme support), (For QtWebKit HTML5 Video), or MySQL, , , and User Notes: If you did not install some of the recommended dependencies, examine ./configure --help output to check how to disable them or use internal versions bundled in the source tarball. If Qt4 is being reinstalled into the same directory as an existing instance, run the commands done by root, such as make install, from a console or non-Qt4 based window manager. It overwrites Qt4 libraries that should not be in use during the install process. The build time and space required for the full Qt is quite long. The instructions below do not build the tutorials and examples. Removing the -nomake lines will create a complete build. Fix DoS vulnerability in the GIF image handler: sed -i -e '631a if (image->isNull()) { state = Error; return -1; }' \ src/gui/image/qgifhandler.cpp Method 1: Installing in /usr Install Qt4 into the /usr hierarchy by running the following commands: export QT4LINK=/usr sed -i -e "/#if/d" -e "/#error/d" -e "/#endif/d" \ config.tests/unix/libmng/libmng.cpp && sed -i '/CONFIG -/ a\isEmpty(OUTPUT_DIR): OUTPUT_DIR = ../..' \ src/3rdparty/webkit/Source/WebKit2/DerivedSources.pro && ./configure -prefix /usr \ -bindir /usr/bin \ -plugindir /usr/lib/qt4/plugins \ -importdir /usr/lib/qt4/imports \ -headerdir /usr/include/qt4 \ -datadir /usr/share/qt4 \ -sysconfdir /etc/xdg \ -docdir /usr/share/doc/qt4 \ -demosdir /usr/share/doc/qt4/demos \ -examplesdir /usr/share/doc/qt4/examples \ -translationdir /usr/share/qt4/translations \ -confirm-license \ -opensource \ -release \ -dbus-linked \ -openssl-linked \ -system-sqlite \ -no-phonon \ -no-phonon-backend \ -no-nis \ -no-openvg \ -nomake demos \ -nomake examples \ -optimized-qmake && make This package does not come with a test suite.

It includes powerful features such as preview mode, automatic widget layout, support for custom widgets, and an advanced property editor. designer linguist provides support for translating applications into local languages. linguist lrelease is a simple command line tool. It reads a Qt project file and produces message files used by the application. lrelease lupdate reads a Qt project file, finds the translatable strings in the specified source, header and Qt Designer interface files, and produces or updates the translation files listed in the project file. lupdate moc generates Qt meta object support code. moc pixeltool is a desktop magnifier and as you move your mouse around the screen it will show the magnified contents in its window. pixeltool qmake uses information stored in project files to determine what should go in the makefiles it generates. qmake qt3to4 qt3to4 is a tool to help update Qt3 code to Qt4. qt3to4 qtconfig is used to customize the appearance of Qt applications. qtconfig rcc is a resource compiler used in conjunction with designer. rcc uic is a Qt user interface compiler. uic uic3 is a tool to generate Qt4 code out of user interface files generated by the Qt3 version of designer. uic3
