%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 Qt is KDE Frameworks 5 (KF5). &lfs82_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 Recommended , , , , (QtMultimedia backend), , , , , , , , , , , , , (Mesa must be built with Wayland EGL backend), , , , and Optional (runtime, used by QtConnectivity module), , , or MySQL, (required for QtWebEngine), , , , and Firebird User Notes: Installing in /opt/qt5 The BLFS editors recommend installing Qt5 in a directory other than /usr, ie /opt/qt5. To do this, set the following environment variable: export QT5PREFIX=/opt/qt5 Sometimes, the installation paths are hardcoded into installed files. This is the reason why /opt/qt5 is used as installation prefix instead of /opt/qt-&qt5-version;. To create a versioned Qt5 directory, you may rename the directory and create a symlink: mkdir /opt/qt-&qt5-version; ln -sfnv qt-&qt5-version; /opt/qt5 Later on, you may want to install other versions of Qt5. To do that, just remove the symlink and use /opt/qt5 as the prefix again. Which version of Qt5 you use depends only on where the symlink points. If Qt5 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-Qt5 based window manager. It overwrites Qt5 libraries that should not be in use during the install process. 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. The build time and space required for the full Qt5 is quite long. The instructions below do not build the tutorials and examples. Removing the -nomake line will create a complete build. The BLFS editors do not recommend installing Qt5 into the /usr hierarchy because it becomes difficult to find components and to update to a new version. If you do want to install Qt5 in /usr, the directories need to be specified explicitly. In this case, set QT5PREFIX=/usr and add the following to the configure arguments below: -archdatadir /usr/lib/qt5 \ -bindir /usr/bin \ -plugindir /usr/lib/qt5/plugins \ -importdir /usr/lib/qt5/imports \ -headerdir /usr/include/qt5 \ -datadir /usr/share/qt5 \ -docdir /usr/share/doc/qt5 \ -translationdir /usr/share/qt5/translations \ -examplesdir /usr/share/doc/qt5/examples Install Qt5 by running the following commands: ./configure -prefix $QT5PREFIX \ -sysconfdir /etc/xdg \ -confirm-license \ -opensource \ -dbus-linked \ -openssl-linked \ -system-harfbuzz \ -system-sqlite \ -nomake examples \ -no-rpath \ -skip qtwebengine && make This package does not come with a test suite. Now, as the root user: make install Remove references to the build directory from installed library dependency (prl) files by running the following command as the root user: find $QT5PREFIX/ -name \*.prl \ -exec sed -i -e '/^QMAKE_PRL_BUILD_DIR/d' {} \; Install images and create the menu entries for installed applications. The QT5BINDIR variable is used here to point to the directory for the executable programs. If you have changed the bindir above, QT5BINDIR will need to be adjusted below. Be sure that the QT5BINDIR variable is defined in root's environment and as the root user: QT5BINDIR=$QT5PREFIX/bin install -v -dm755 /usr/share/pixmaps/ && 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 && install -dm755 /usr/share/applications && cat > /usr/share/applications/assistant-qt5.desktop << EOF [Desktop Entry] Name=Qt5 Assistant Comment=Shows Qt5 documentation and examples Exec=$QT5BINDIR/assistant Icon=assistant-qt5.png Terminal=false Encoding=UTF-8 Type=Application Categories=Qt;Development;Documentation; EOF cat > /usr/share/applications/designer-qt5.desktop << EOF [Desktop Entry] Name=Qt5 Designer GenericName=Interface Designer Comment=Design GUIs for Qt5 applications Exec=$QT5BINDIR/designer Icon=designer-qt5.png MimeType=application/x-designer; Terminal=false Encoding=UTF-8 Type=Application Categories=Qt;Development; EOF cat > /usr/share/applications/linguist-qt5.desktop << EOF [Desktop Entry] Name=Qt5 Linguist Comment=Add translations to Qt5 applications Exec=$QT5BINDIR/linguist Icon=linguist-qt5.png MimeType=text/vnd.trolltech.linguist;application/x-linguist; Terminal=false Encoding=UTF-8 Type=Application Categories=Qt;Development; EOF cat > /usr/share/applications/qdbusviewer-qt5.desktop << EOF [Desktop Entry] Name=Qt5 QDbusViewer GenericName=D-Bus Debugger Comment=Debug D-Bus applications Exec=$QT5BINDIR/qdbusviewer Icon=qdbusviewer-qt5.png Terminal=false Encoding=UTF-8 Type=Application Categories=Qt;Development;Debugger; EOF Some packages such as look for certain executables with a -qt5 suffix.

The BLFS editors have chosen to build separately. -system-harfbuzz: This switch enables use of the system version of Harfbuzz which fixes some font rendering issues in Qt5 applications but doesn't have all the features that the included one has. If you installed Qt5 in /usr, create an environment variable needed by certain packages.
