      How do I build QtLua with QtUiTools enabled? I was successful at building Qt 5.12.8 (from https://wiki.qt.io/Building_Qt_5_from_Git) and qtlua, but when I run the qtlua example, I get this error message:
      phan@ubuntu:/usr/local/src/libqtlua/examples/lua/hello_uiload$ qtlua hello.lua
      [string ""]:7: new_qobject:QtLua has been compiled without support for Qt uitools module.

      What is the proper procedure for building Qt5 & qtlua so that there will be support for Qt uitools module?
      Thank you.
      PS I am using Ubutu 20.4

        Hi and welcome to devnet,

        Can you share the exact configure line you used ?
        Can you also post the configuration summary ? There might be some hints there.
        Also, how did you proceed to build QtLua ? Just to check whether you used your custom build of Qt.

          These are my steps:
          git clone git://code.qt.io/qt/qt5.git
          cd qt5/
          git checkout 5.12.8
          perl init-repository
          mkdir ../qt5-build ; cd ../qt5-build
          ../qt5/configure -developer-build -opensource -nomake tests -confirm-license

          Before I type "make", I edit this file below to include "QT += uitools":
          /usr/local/src/qt5/qtbase/util/accessibilityinspector/accessibilityinspector.pri:
          # DEFINES += ACCESSIBILITYINSPECTOR_NO_UITOOLS
          QT += uitools # before, this was commented out

          I think the first time I built without the "QT += uitools", the directory below didn't get created:
          /usr/local/src/qt5-build/qtbase/include/QtUiTools/QUiLoader

          Then I built libqtlua with:
          cd libqtlua
          mkdir bld2
          cd bld2
          cmake ..
          make

          It tries to link shared libs in /usr/lib/x86_64-linux-gnu but I just change that manually to use shared libs in /usr/local/src/qt5-build/qtbase/lib via:

          /usr/bin/c++    -rdynamic CMakeFiles/qtlua_app.dir/qtlua.cc.o  -o qtlua  -Wl,-rpath,/usr/local/src/libqtlua/bld2/src:  ../../src/libqtlua.so /usr/local/src/qt5-build/qtbase/lib/libQt5Widgets.so.5.12.8 /usr/local/src/qt5-build/qtbase/lib/libQt5Gui.so.5.12.8 /usr/local/src/qt5-build/qtbase/lib/libQt5Core.so.5.12.8 /usr/local/lib/liblua.a /usr/local/src/qt5-build/qttools/src/designer/src/uitools/.obj/libQt5UiTools.so -lm -ldl 
/usr/bin/ld: ../../src/libqtlua.so: undefined reference to `QUiLoader::createWidget(QString const&, QWidget*, QString const&)'
/usr/bin/ld: ../../src/libqtlua.so: undefined reference to `QUiLoader::QUiLoader(QObject*)'
/usr/bin/ld: ../../src/libqtlua.so: undefined reference to `QUiLoader::~QUiLoader()'
/usr/bin/ld: ../../src/libqtlua.so: undefined reference to `QUiLoader::load(QIODevice*, QWidget*)'
collect2: error: ld returned 1 exit status

          The libQt5UiTools.so I created myself manually via:
          $ cd /usr/local/src/qt5-build/qttools/src/designer/src/uitools/.obj
          $ g++ -shared -o libQt5UiTools.so *.o
          Since I know the "QUiLoader::QUiLoader(QObject*)" is in those *.o. But when I link the qtlua above, why do I still have undefined reference to QUiLoader::QUiLoader(QObject*)?

          Thanks for your help.

            Looks like your call to cmake in QtLua detects your system's Qt. You likely have to tell it where to find your self-built Qt.

              It didn't detect it (I forgot to mention), so I just edit the to include as if it had detected it:
              /usr/local/src/libqtlua/bld2/config.hh
              #define HAVE_QT_UITOOLS 1
              and then manually link it. But still it's not finding the "QUiLoader::QUiLoader(QObject*)". Do you know how to fix that? Thanks.

                That's the thing, you should rebuild QtLua from scratch ensuring that your custom Qt is detected rather than manually fiddling with the generated files.

                  @SGaist I don't know how to fix QtLua's cmake to make it detect my custom Qt. It detects the Qt5 that was installed via apt install, but that doesn't have the QUiLoader either. Qt5 should have QUiLoader built by the default, but they don't. Even when I forced it with "QT += uitools", it didn't build the libQt5UiTools.so for me; I had to build it with "g++ -shared -o libQt5UiTools.so .o". Is this the proper way to build QtUiTools? The QUiLoader::QUiLoader(QObject) is in my libQt5UiTools.so, but why doesn't it work?

                    You have to pass -DCMAKE_PREFIX_PATH and give it the path to your custom Qt cmake files.

                    The ui tools module should have been built so there something off but I do not currently see anything obvious.

                      @SGaist I tried that but libqtlua still couldn't figured out to use uitools. I did got it to work by fixing the libqtlua.so library by adding /usr/local/src/qt5-build/qtbase/lib/libQt5UiTools.a to the generation of libqtlua.so via:

                      then type "make" and that's it. Once libqtlua.so has the Qt5UiTools symbols through the .a, then the problem is fixed. Wish it just worked out of the box though. Thanks.
