%general-entities; ]> $LastChangedBy$ $Date$ 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. &lfs72_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &qt-md5sum; Download size: &qt-size; Estimated disk space required: &qt-buildsize; Estimated build time: &qt-time; Qt Dependencies Required Recommended , , , , and (needed to use D-Bus, GLib, GTK and PulseAudio) Optional , , , , , , , , and User Notes: There are several ways to install a complicated package such as Qt. The files are not completely position independent. Installation procedures execute the program pkg-config to determine the location of package executables, libraries, headers, and other files. For Qt, pkg-config will look for the appropriate lib/pkgconfig/Qt*.pc files which must be modified if relocating the package. These files are set up correctly by the build process. The default installation places the files in /usr/local/qt/. Many commercial distributions place the files in the system's /usr hierarchy. The package can also be installed in an arbitrary directory. The advantage of installing in /usr is that no updates to the /etc/ld.so.conf or /etc/man_db.conf files are required. The package files are distributed within several subdirectories of the /usr hierarchy. This is the method that most commercial distributions use. If Qt is being reinstalled and the /usr directory is used as the prefix, run the following commands from a console or non-Qt based window manager. It overwrites Qt 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. The method recommended by the Qt developers does not use the /usr directory prefix. It has the advantage of keeping all the package files consolidated in a dedicated directory hierarchy. By using this method, an update can be made without overwriting a previous installation and users can easily revert to a previous version by changing one symbolic link. The Qt developers use a default location of /usr/local/qt/, however the procedure below puts the files in /opt/qt-&qt-version;/ and then creates a symbolic link to /opt/qt/. Configure Qt by running the following commands: ./configure -prefix /opt/qt-&qt-version; \ -release \ -nomake examples \ -nomake demos \ -system-sqlite \ -no-nis \ -opensource \ -confirm-license && make If KDE is intended to be installed, add -no-phonon to the ./configure command above. While installing KDE, a separate version of the Phonon libraries will be installed which better matches the needs of the KDE desktop. This package does not come with a test suite. Now, as the root user: make install If you installed Qt in the /opt directory, again as the root user issue: ln -svfn qt-&qt-version; /opt/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 Qt developer. -system-sqlite: Use the system version of SQLite. -no-nis: Disable support for Network Information Service (NIS). -opensource: Install the opensource version of Qt. -confirm-license: Accept license without prompting user during configuration. -plugin-sql-<driver> or -qt-sql-<driver>: These switches build SQL support into the Qt libraries. To check if mysql is autodetected properly, examine the output of ./configure -qt-sql-mysql -help. Other database support will require similar configure parameters. There are several optional directories that can be specified in the ./configure line. These include -bindir, -libdir, -docdir, and -headerdir. For a complete list, run ./configure -help. If you installed Qt in /usr, create an environment variable needed by certain packages. As the root user: cat > /etc/profile.d/qt.sh << EOF # Begin /etc/profile.d/qt.sh QTDIR=/usr export QTDIR # End /etc/profile.d/qt.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/qt/lib # End Qt addition EOF ldconfig /etc/ld.so.conf As the root user, create the /etc/profile.d/qt.sh file: cat > /etc/profile.d/qt.sh << EOF # Begin /etc/profile.d/qt.sh QTDIR=/opt/qt pathappend /opt/qt/bin PATH pathappend /opt/qt/lib/pkgconfig PKG_CONFIG_PATH export QTDIR # End /etc/profile.d/qt.sh EOF Installed Programs Installed Libraries Installed Directories assistant, designer, lconvert, linguist, lrelease, lupdate, moc, pixeltool, qcollectiongenerator, qdbus, qdbuscpp2xml, qdbusviewer, qdbusxml2cpp, qdoc3, qhelpconverter, qhelpgenerator, qmake, qmlplugindump, qmlviewer, qt3to4, qtconfig, qttracereplay, rcc, uic, uic3, xmlpatterns and xmlpatternsvalidator libphonon.so, libQt3Support.so, libQtCLucene.so, libQtCore.so, libQtDBus.so, libQtDeclarative.so, libQtDesigner.so, libQtDesignerComponents.so, libQtGui.so, libQtHelp.so, libQtMultimedia, libQtNetwork.so, libQtOpenGL.so, libQtScript.so, libQtScriptTools.so, libQtSql.so, libQtSvg.so, libQtTest.so, libQtUiTools.a, libQtWebKit.so, libQtXml.so, libQtXmlPatterns.so and numerous plugin modules installed in /opt/qt/plugins /opt/qt-&qt-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 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
