Building 5.12.3 on Ubuntu 19.04 results in missing x11extras module

  • I downloaded qt-everywhere-src-5.12.3.tar.xz, extracted and configured with

    OPENSSL_LIBS='-L/usr/lib/x86_64-linux-gnu -lssl -lcrypto' $SRC_FOLDER/configure -release -opensource -confirm-license -prefix $PREFIX_FOLDER -openssl-linked -static -optimize-size -ltcg -nomake examples -nomake tests -nomake tools -skip qtwebengine -skip qtdeclarative

    It seems to finish just fine but when trying to build a project I get

    Project ERROR: Unknown module(s) in QT: x11extras

    The only relevant part that happens during make is

    cd qtx11extras/ && ( test -e Makefile || /home/skyweb/Qt/5.12.3/64_static-build/qtbase/bin/qmake -o Makefile /home/skyweb/Qt/5.12.3/qt-everywhere-src-5.12.3/qtx11extras/ ) && make -f Makefile install
    make[1]: Entering directory '/home/skyweb/Qt/5.12.3/64_static-build/qtx11extras'
    cd src/ && ( test -e Makefile || /home/skyweb/Qt/5.12.3/64_static-build/qtbase/bin/qmake -o Makefile /home/skyweb/Qt/5.12.3/qt-everywhere-src-5.12.3/qtx11extras/src/ ) && make -f Makefile install
    make[2]: Entering directory '/home/skyweb/Qt/5.12.3/64_static-build/qtx11extras/src'
    make[2]: Nothing to be done for 'install'.
    make[2]: Leaving directory '/home/skyweb/Qt/5.12.3/64_static-build/qtx11extras/src'

    Hi and welcome to devnet,

    Did you check the configure logs to see if there's something related to that ?

    Do you have the required dependencies for that module ?

  • The configure logs don't show anything related to x11extras ( I changed the configure with skipping more which is more in line with what I actually need (and builds on windows).

    I'm not sure what dependencies specifically there are but I'm not getting any messages indicating it's missing any.

    What do you get if you build the x11extras module manually ? (meaning creating a new folder, using your custom Qt qmake to setup the build and then calling make)

  • skyweb@vm:~/qt/5.12.3/x11$ /home/skyweb/qt/5.12.3/64_static/bin/qmake /home/skyweb/qt/5.12.3/qt-everywhere-src-5.12.3/qtx11extras/
    Info: creating stash file /home/skyweb/qt/5.12.3/x11/.qmake.stash
    Info: creating cache file /home/skyweb/qt/5.12.3/x11/.qmake.cache
    skyweb@vm:~/qt/5.12.3/x11$ make
    cd src/ && ( test -e Makefile || /home/skyweb/qt/5.12.3/64_static/bin/qmake -o Makefile /home/skyweb/qt/5.12.3/qt-everywhere-src-5.12.3/qtx11extras/src/ ) && make -f Makefile 
    make[1]: Entering directory '/home/skyweb/qt/5.12.3/x11/src'
    make[1]: Nothing to be done for 'first'.
    make[1]: Leaving directory '/home/skyweb/qt/5.12.3/x11/src'

    And of course nothing appears.
    makefile in case it's useful.

  • Well, I tried it again with the below

    OPENSSL_LIBS='-L/usr/lib/x86_64-linux-gnu -lssl -lcrypto' $SRC_FOLDER/configure -release -opensource -confirm-license -prefix $PREFIX_FOLDER -openssl-linked -static -optimize-size -ltcg -nomake examples -nomake tests -nomake tools -skip qt3d -skip qtactiveqt -skip qtcanvas3d -skip qtconnectivity -skip qtdeclarative -skip qtdatavis3d -skip qtdoc -skip qtgamepad -skip qtcharts -skip qtgraphicaleffects -skip qtlocation -skip qtnetworkauth -skip qtpurchasing -skip qtquickcontrols -skip qtquickcontrols2 -skip qtremoteobjects -skip qtscxml -skip qtsensors -skip qtserialbus -skip qtserialport -skip qtspeech -skip qtvirtualkeyboard -skip qtwebchannel -skip qtwebengine -skip qtwebview -skip qtscript
    make install

    And it actually doesn't complain that x11extras isn't found

    Getting other issues when building my project, related to wayland-xdg-shell and qharfbuzz: compile log These aren't errors. Guess my issue is solved without changing anything related to configure/make.

  • I am trying to build 5.12.3 on CentOS7. Qt5X11Extras module will NOT build along with the other modules. I tried the above suggestions but it still does not work.
    Question: Do I need "root" access for this to work? I am building in my own directory.

    No you don't need root access.

    Did you check the configure tests logs to see if you are missing some libraries ?
