%general-entities; ]> $LastChangedBy$ $Date$ Qt Qt5 is a cross-platform application framework that is widely used for developing application software with a graphical user interface (GUI) (in which cases Qt5 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 Qt5 is KDE Frameworks 5. &lfs74_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &qt5-md5sum; Download size: &qt5-size; Estimated disk space required: &qt5-buildsize; Estimated build time: &qt5-time; Qt5 Dependencies Required , , , , , and Recommended , , , , , , , , , , , , and Optional (QtWebKit HTML5 Video Support), (GTK+ Theme Support), libxkbcommon, or , , , and Required (Runtime) (if installing both Qt4 and Qt5 and installing in /usr) User Notes: There are several ways to install a complicated package such as Qt5. 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 Qt5, pkg-config will look for the appropriate lib/pkgconfig/Qt5*.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 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 distributions use. 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 programs from . The advantage of installing Qt5 in a custom directory such as /opt/qt-&qt5-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 Qt5 is being reinstalled into the same directory as an existing instance, run the following commands from a console or non-Qt5 based window manager. It overwrites Qt5 libraries that should not be in use during the install process. Method 1: Installing in /usr Install Qt5 by running the following commands: If not also installing Qt4 into the /usr directory, change the entry for -bindir below to /usr/bin. sed -e "s:#if MNG:#if defined(MNG_VERSION_MAJOR)\n&:" \ -e "s:#endif:&\n#endif:" \ -i qtimageformats/config.tests/libmng/libmng.cpp ./configure -prefix /usr \ -sysconfdir /etc/xdg \ -bindir /usr/lib/qt5/bin \ -headerdir /usr/include/qt5 \ -archdatadir /usr/lib/qt5 \ -datadir /usr/share/qt5 \ -docdir /usr/share/doc/qt5 \ -translationdir /usr/share/qt5/translations \ -examplesdir /usr/share/doc/qt5/examples \ -confirm-license \ -opensource \ -dbus-linked \ -openssl-linked \ -system-sqlite \ -no-nis \ -nomake examples \ -opengl es2 \ -optimized-qmake && make Remove references to the build directory from the .pc files by running the following command: find . -name "*.pc" -exec perl -pi -e "s, -L$PWD/?\S+,,g" {} \; This package does not come with a test suite. Now, as the root user: make install && install -v -Dm644 qttools/src/assistant/assistant/images/assistant-128.png \ /usr/share/pixmaps/assistant-qt5.png && install -v -Dm644 qttools/src/designer/src/designer/images/designer.png \ /usr/share/pixmaps/designer-qt5.png && install -v -Dm644 qttools/src/linguist/linguist/images/icons/linguist-128-32.png \ /usr/share/pixmaps/linguist-qt5.png && install -v -Dm644 qttools/src/qdbus/qdbusviewer/images/qdbusviewer-128.png \ /usr/share/pixmaps/qdbusviewer-qt5.png Remove references to the build directory from installed files by running the following commands as the root user: sed -i -e "s:$PWD/qtbase:/usr/lib/qt5:g" \ /usr/lib/qt5/mkspecs/modules/qt_lib_bootstrap_private.pri && find /usr/lib/lib{qgsttools_p,Qt5*}.prl -exec sed -i -e \ '/^QMAKE_PRL_BUILD_DIR/d;s/\(QMAKE_PRL_LIBS =\).*/\1/' {} \; If you didn't modify the -bindir switch above, symlink the Qt5 executables into /usr/bin by running the following commands as the root user: for file in /usr/lib/qt5/bin/* do ln -sfv ../lib/qt5/bin/$(basename $file) /usr/bin/$(basename $file)-qt5 done Method 2: Installing in /opt/qt-&qt5-version; This section provides an alternate way to install Qt5 by installing almost all of the files in the /opt directory. This allows management of all Qt5 related files in one unit. For instance, a new version of Qt5 can be installed without over-writing the existing installation and entire Qt5 instances can be easily removed. However, it has the disadvantage of needing some extra configuration and you need to switch manually between Qt4 and Qt5 executables when needed. sed -e "s:#if MNG:#if defined(MNG_VERSION_MAJOR)\n&:" \ -e "s:#endif:&\n#endif:" \ -i qtimageformats/config.tests/libmng/libmng.cpp QT5DIR=/opt/qt-&qt5-version; ./configure -prefix $QT5DIR \ -sysconfdir /etc/xdg \ -confirm-license \ -opensource \ -dbus-linked \ -openssl-linked \ -system-sqlite \ -plugin-sql-sqlite \ -no-nis \ -nomake examples \ -opengl es2 \ -optimized-qmake && make Now, as the root user: make install && install -v -Dm644 qttools/src/assistant/assistant/images/assistant-128.png \ /usr/share/pixmaps/assistant-qt5.png && install -v -Dm644 qttools/src/designer/src/designer/images/designer.png \ /usr/share/pixmaps/designer-qt5.png && install -v -Dm644 qttools/src/linguist/linguist/images/icons/linguist-128-32.png \ /usr/share/pixmaps/linguist-qt5.png && install -v -Dm644 qttools/src/qdbus/qdbusviewer/images/qdbusviewer-128.png \ /usr/share/pixmaps/qdbusviewer-qt5.png Remove references to the build directory from installed files by running the following commands as the root user: find $QT5DIR -name qt_lib_bootstrap_private.pri \ -exec sed -i -e "s:$PWD/qtbase:/$QT5DIR/lib/:g" {} \; && find $QT5DIR -name \*.prl \ -exec sed -i -e '/^QMAKE_PRL_BUILD_DIR/d' {} \; Symlink the Qt5 executables into /usr/bin by running the following commands as the root user: ln -svf $QT5DIR /opt/qt5 && for file in /opt/qt5/bin/*; do ln -sfv $file /usr/bin/$(basename $file)-qt5 done sed -e "..." -e "..." -i ...: This command fixes detection of libmng 2.0. -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: This switch disables building of the example programs included in the source tarball.
