Qt's -primary feature is its rich set of widgets that provide -standard GUI functionality. - -The following are optional dependencies that Qt will link -against if they are detected at build time: - -libwebp, opus, ffmpeg, re2, snappy, libminizip, jsoncpp, -libinput, unixODBC, postgresql, SDL2, assimp, wayland, -OpenAL, protobuf(3?), argon2, and perhaps more. - -============================================================ - -OPTIONS - -To use Qt's built-in ccache option: - - CCACHE=yes ./qt5.SlackBuild - -To build the documentation: - - DOCS=yes ./qt5.SlackBuild - -(you will need the llvm package from extra/ to build -documentation) - -To build the examples: - - EXAMPLES=yes ./qt5.SlackBuild - -To build support for proprietary media codecs: - - PROPRIETARY_CODECS=yes ./qt5.SlackBuild - -(this will produce a non-redistributable package in some -countries) - -To disable support for pulseaudio: - - PULSEAUDIO=no ./qt5.SlackBuild - -(Qt will automatically detect if pulseaudio is not installed -at build time and disable it if it is missing.) - -To NOT build qtwebengine (EXPERIMENTAL): - - WEBENGINE=no ./qt5.SlackBuild - -To use the gold linker: - - LDGOLD=yes ./qt5.SlackBuild - -This may speed up the build, but can take more RAM. - -Combine any or all of the above. - -============================================================ - -GENERAL NOTES - -After upgrading Qt5 it is important to rebuild qt5ct too, if -it is installed, or some applications may not display or -function correctly. - -There is a qt5-legacy (5.9.9) SlackBuild that is available -for older applications that do not run correctly with this -version. However it will not coexist with this version. - -Please report any problems about applications that don't -work correctly to the Qt5 maintainer or to the mailing list. - -============================================================ - -NOTES ON OPTIONS - -* Using ccache should speed up subsequent rebuilds, but may - be slower for first time or one-off builds. - -* Building the documentation and/or examples creates a - significantly larger package. - -============================================================ - -BUILDING WITHOUT WEBENGINE - -Building without webengine can speed up compilation. - -If you have no intention of using the browser code, which -includes a chunk of 3rd party Google Chromium source, then -it may make sense to skip it and save yourself about 2/3 of -the build time, and knocks about 3G off the needed space. - -The package version has _nowebengine appended to it for -clarity. - -* Successfully tested so far without webengine (VERY quick - tests): - - QMPlay2 - qt5ct - qbittorrent-qt5 - speedcrunch - qca-qt5 - psi-plus - sddm - -============================================================ - -TROUBLESHOOTING - -If Qt5 fails to build, it may be worth using the following -steps. - -1 Uninstall the old Qt5 package -2 Log out of root -3 Log back in as root -4 Build and install the new package -5 Log out of root -6 Log back in as root -7 Upgrade all other packages that depend on Qt5 - -The reasoning behind all the log outs/ins, is because Qt5 -installs /etc/profile.d/qt5.sh that sets QT5DIR and adds -QT5DIR/bin to your $PATH when you log in (there's a similar -file for csh.) Even though the old Qt5 is removepkg'd, those -settings are *still there* until you log out. - -You can see with a test (assuming bash or a zsh type shell): - -env | grep -i qt5 - -If that command is used before step 4, you shouldn't see -anything qt5 related in PATH and QT5DIR shouldn't exist. - |
