%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. &lfs74_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 (runtime, if also installing Qt5 and installing in /usr) 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. It is also supported by the optional qtchooser application. The disadvantage of installing in /usr is that the executable filenames for Qt4 and Qt5 conflict if both packages are installed in the same directory. The instructions below give a workaround for this problem using the helper program . This requires renaming the Qt executables with a version suffix. The advantage of installing Qt4 in a custom directory such as /opt/qt-&qt4-version; is that it keeps 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 or merely changing the PATH variable. It also allows a developer to maintain multiple versions of Qt4 or Qt5 for testing. 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 by running the following commands: If not also installing Qt5 into the /usr directory, change the entry for -bindir below to /usr/bin. 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/lib/qt4/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$PWD/?\S+,,g" {} \; Now, as the root user: make install && rm -rf /usr/tests && install -v -Dm644 src/gui/dialogs/images/qtlogo-64.png \ /usr/share/pixmaps/qt4logo.png && install -v -Dm644 tools/assistant/tools/assistant/images/assistant-128.png \ /usr/share/pixmaps/assistant-qt4.png && install -v -Dm644 tools/designer/src/designer/images/designer.png \ /usr/share/pixmaps/designer-qt4.png && install -v -Dm644 tools/linguist/linguist/images/icons/linguist-128-32.png \ /usr/share/pixmaps/linguist-qt4.png && install -v -Dm644 tools/qdbus/qdbusviewer/images/qdbusviewer-128.png \ /usr/share/pixmaps/qdbusviewer-qt4.png Remove references to the build directory from installed files by running the following command as the root user: for file in 3Support CLucene Core DBus Declarative DesignerComponents \ Designer Gui Help Multimedia Network OpenGL Script \ ScriptTools Sql Svg Test UiTools WebKit XmlPatterns Xml phonon do [ -e /usr/lib/libQt${file}.prl ] && sed -i -e '/^QMAKE_PRL_BUILD_DIR/d;s/\(QMAKE_PRL_LIBS =\).*/\1/' \ /usr/lib/libQt${file}.prl done unset file If also installing Qt5 into /usr, symlink the Qt4 executables into /usr/bin by running the following commands as the root user: for file in /usr/lib/qt4/bin/* do ln -sfv ../lib/qt4/bin/$(basename $file) /usr/bin/$(basename $file)-qt4 done Method 2: Installing in /opt/qt-&qt4-version; This section provides an alternate way to install Qt4 by installing almost all of the files in the /opt directory. This allows management of all Qt4 related files in one unit. For instance, a new version of Qt4 can be installed without over-writing the existing installation and entire Qt4 instances can be easily removed. However, it has the disadvantage of needing some extra configuration. Install Qt in /opt/qt-&qt4-version; by running the following commands: 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 && export QTDIR=/opt/qt-&qt4-version; ./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 qt-&qt4-version; /opt/qt && 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 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 -i -e '/^QMAKE_PRL_BUILD_DIR/d;s/\(QMAKE_PRL_LIBS =\).*/\1/' \ $QTDIR/lib/${file}.prl perl -pi -e "s, -L$PWD/?\S+,,g" $QTDIR/lib/pkgconfig/${file##lib}.pc done unset file sed -i ...: First command fixes detection of libmng 2.0 and second one prevents configure script to write in 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 Qt developer. -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.
