%general-entities; ]> $LastChangedBy$ $Date$ Qt-&qt4-version; Qt Introduction to Qt Qt is a cross-platform application framework that is widely used for developing application software with a graphical user interface (GUI) (in which cases Qt is classified as a widget toolkit), and also used for developing non-GUI programs such as command-line tools and consoles for servers. One of the major users of Qt is KDE. &lfs75_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 , , , and User Notes: Installation of Qt 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 following commands 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. Method 1: Installing in /usr Install Qt4 into the /usr hierarchy by running the following commands: export QTLINK=/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. Remove references to the build directory from the .pc files by running the following command: find . -name "*.pc" -exec perl -pi -e "s, -L$PWD/?\S+,,g" {} \; Now as the root user: make install && rm -rf /usr/tests Remove references to the build directory from installed files by running the following command as the root user: for file in 3Support CLucene Core DBus Declarative DesignerComponents \ Designer Gui Help Multimedia Network OpenGL Script \ ScriptTools Sql Svg Test UiTools WebKit XmlPatterns Xml phonon; do [ -e /usr/lib/libQt${file}.prl ] && sed -r '/^QMAKE_PRL_BUILD_DIR/d;s/(QMAKE_PRL_LIBS =).*/\1/' \ -i /usr/lib/libQt${file}.prl done unset file Method 2: Installing in /opt/qt-&qt4-version; This section provides for installing Qt4 almost all of the files in the /opt directory. export QTDIR=/opt/qt-&qt4-version; && export QTLINK=/opt/qt4 && 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 $QTDIR \ -sysconfdir /etc/xdg \ -confirm-license \ -opensource \ -release \ -dbus-linked \ -openssl-linked \ -system-sqlite \ -plugin-sql-sqlite \ -no-phonon \ -no-phonon-backend \ -no-nis \ -no-openvg \ -nomake demos \ -nomake examples \ -optimized-qmake && make Now, as the root user: make install ln -svfn $QTDIR /opt/qt4 Remove references to the build directory from installed files by running the following command as the root user: for file in `basename -a -s .prl $QTDIR/lib/lib*.prl`; do sed -r -e '/^QMAKE_PRL_BUILD_DIR/d' \ -e 's/(QMAKE_PRL_LIBS =).*/\1/' \ -i $QTDIR/lib/${file}.prl perl -pi -e "s, -L$PWD/?\S+,,g" $QTDIR/lib/pkgconfig/${file##lib}.pc done unset file Continuing for Both Methods For all methods, install images and create the menu entries for installed applications. Be sure that the QTLINK variable is defined in root's environment and as the root user: install -v -Dm644 src/gui/dialogs/images/qtlogo-64.png \ /usr/share/pixmaps/qt4logo.png && install -v -Dm644 tools/assistant/tools/assistant/images/assistant-128.png \ /usr/share/pixmaps/assistant-qt4.png && install -v -Dm644 tools/designer/src/designer/images/designer.png \ /usr/share/pixmaps/designer-qt4.png && install -v -Dm644 tools/linguist/linguist/images/icons/linguist-128-32.png \ /usr/share/pixmaps/linguist-qt4.png && install -v -Dm644 tools/qdbus/qdbusviewer/images/qdbusviewer-128.png \ /usr/share/pixmaps/qdbusviewer-qt4.png && install -dm755 /usr/share/applications && cat > /usr/share/applications/assistant-qt4.desktop << EOF [Desktop Entry] Name=Qt4 Assistant Comment=Shows Qt4 documentation and examples Exec=$QTLINK/bin/assistant Icon=assistant-qt4.png Terminal=false Encoding=UTF-8 Type=Application Categories=Qt;Development;Documentation; EOF cat > /usr/share/applications/designer-qt4.desktop << EOF [Desktop Entry] Name=Qt4 Designer Comment=Design GUIs for Qt4 applications Exec=$QTLINK/bin/designer Icon=designer-qt4.png MimeType=application/x-designer; Terminal=false Encoding=UTF-8 Type=Application Categories=Qt;Development; EOF cat > /usr/share/applications/linguist-qt4.desktop << EOF [Desktop Entry] Name=Qt4 Linguist Comment=Add translations to Qt4 applications Exec=$QTLINK/bin/linguist Icon=linguist-qt4.png MimeType=text/vnd.trolltech.linguist;application/x-linguist; Terminal=false Encoding=UTF-8 Type=Application Categories=Qt;Development; EOF cat > /usr/share/applications/qdbusviewer-qt4.desktop << EOF [Desktop Entry] Name=Qt4 QDbusViewer GenericName=D-Bus Debugger Comment=Debug D-Bus applications Exec=$QTLINK/bin/qdbusviewer Icon=qdbusviewer-qt4.png Terminal=false Encoding=UTF-8 Type=Application Categories=Qt;Development;Debugger; EOF cat > /usr/share/applications/qtconfig-qt4.desktop << EOF [Desktop Entry] Name=Qt4 Config Comment=Configure Qt4 behavior, styles, fonts Exec=$QTLINK/bin/qtconfig Icon=qt4logo.png Terminal=false Encoding=UTF-8 Type=Application Categories=Qt;Settings; EOF Command Explanations sed -i ...: First command fixes detection of libmng 2.0 and second one prevents configure script from writing to the root directory if building as privileged user. -confirm-license: Accept license without prompting user during configuration. -opensource: Install the opensource version of Qt. -release: This switch disables building with debugging symbols. -nomake examples -nomake demos: These switches disable building programs that are only of interest to a developer using Qt. -system-sqlite: This switch enables use the system version of SQLite. -no-nis: This switch disables support for Network Information Service (NIS) which has been deprecated in recent versions of Glibc. -no-phonon -no-phonon-backend: These switches disable building of the bundled Phonon library. Better version is provided by package. -dbus-linkend -openssl-linkend: These switches enable explicit linking of the D-Bus and OpenSSL libraries into Qt libraries instead of dlopen()-ing them. -no-openvg: This switch disables OpenVG support in Qt. -optimized-qmake: This switch enables building of the optimized qmake program. : Use this switch if you don't have D-Bus installed. Configuring Qt Configuration Information If you installed Qt in /usr, create an environment variable needed by certain packages. As the root user: cat > /etc/profile.d/qt4.sh << EOF # Begin /etc/profile.d/qt4.sh QTDIR=/usr export QTDIR # End /etc/profile.d/qt4.sh EOF If you installed Qt in a location other than /usr, you need to update the following configuration files so that Qt is correctly found by other packages and system processes. As the root user, update the /etc/ld.so.conf file and the dynamic linker's run-time cache file: cat >> /etc/ld.so.conf << EOF # Begin Qt addition /opt/qt4/lib # End Qt addition EOF ldconfig /etc/ld.so.conf As the root user, create the /etc/profile.d/qt4.sh file: cat > /etc/profile.d/qt4.sh << EOF # Begin /etc/profile.d/qt4.sh QTDIR=/opt/qt4 pathappend /opt/qt4/bin PATH pathappend /opt/qt4/lib/pkgconfig PKG_CONFIG_PATH export QTDIR # End /etc/profile.d/qt4.sh EOF Contents Installed Programs Installed Libraries Installed Directories assistant, designer, lconvert, linguist, lrelease, lupdate, moc, pixeltool, qcollectiongenerator, qdbuscpp2xml, qdbus, qdbusviewer, qdbusxml2cpp, qdoc3, qhelpconverter, qhelpgenerator, qmake, qmlplugindump, qmlviewer, qt3to4, qtconfig, qttracereplay, rcc, uic3, uic, xmlpatterns, and xmlpatternsvalidator libQt3Support.so, libQtCLucene.so, libQtCore.so, libQtDBus.so, libQtDeclarative.so, libQtDesignerComponents.so, libQtDesigner.so, libQtGui.so, libQtHelp.so, libQtMultimedia.so, libQtNetwork.so, libQtOpenGL.so, libQtScript.so, libQtScriptTools.so, libQtSql.so, libQtSvg.so, libQtTest.so, libQtWebKit.so, libQtXmlPatterns.so, and libQtXml.so /usr/include/qt4, /usr/lib/qt4, /usr/share/doc/qt4, and /usr/share/qt4 OR /opt/qt4 and /opt/qt-&qt4-version; Short Descriptions assistant is a tool for presenting on-line documentation. assistant designer is a full-fledged GUI builder. 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
