Qt Creator and other tools

QString::toAscii() is deprecated in Qt5 and removed in Qt6. But the documentation tells you how you can replace it.

@Wallie a wild shot in the dark here, since you don't give us much information. select QtCreator (which I'm assuming you're using) press ctrl + down arrow select the (presumably) hidden popup window. Proceed from there.

Hi, As already suggested by @sierdzio, stop using sudo until the point of installation. Doing build as root is risky. If something goes wrong you might nuke your system without even noticing before it's too late. Which exact error do you have now ?

Simply disable this check for clazy in the analyzer settings. CLazy does not know if it's Qt5 or Qt6. In Qt5 QList was not optimal, in Qt6 QVector was renamed to QList ... maybe the next clazy version can somehow fiddle out what Qt version it's currently checking.

Yes, I see what you mean. There is a graphical view of signals and slots but it works only for connections between UI elements. Tap F4 to get to it. But what you wrote is a great suggestion, please if you have some time report it on Qt bugtracker as a feature request!

I discovered that it can be made to work, if you wait some time after it plays, and then change position of playback (even back to the same position). If you do it too soon (e.g. set position 0 right on start) then it doesn't work. Not sure what is the event on which that needs to be done to correctly apply the speed/playbackrate setting, so in worst case one can have a timer that keeps calling setposition back to current position all the time. It's kinda hack but it works. Is there a better way?

@VRonin It also was spoiled to \\A\([^/]:[^\\ When I opened the first time it was like this: https://drive.google.com/file/d/1epZFK0OGbFZEf1TAzV57XUzmobKUbao-/view?usp=sharing and I done new one in the same way. For Windows version, saving of "Ignored File Templates" also doesn't work. And this option doesn't work for highlighting in any case, because it for some "generic highlighter" and not used for case editing cpp files.

@jsulm For me qmake projects works fine but CMake projects failed because of the following error: FAILED: Raspberrydemo : && /opt/qt5pi/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++ -g CMakeFiles/Raspberrydemo.dir/Raspberrydemo_autogen/mocs_compilation.cpp.o CMakeFiles/Raspberrydemo.dir/main.cpp.o CMakeFiles/Raspberrydemo.dir/Raspberrydemo_autogen/EWIEGA46WW/qrc_qml.cpp.o -o Raspberrydemo -Wl,-rpath,/opt/qt5pi/sysroot/usr/local/qt5pi/lib /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Quick.so.5.15.2 /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Gui.so.5.15.2 /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5QmlModels.so.5.15.2 /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Qml.so.5.15.2 /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Network.so.5.15.2 /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Core.so.5.15.2 && : /opt/qt5pi/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/7.5.0/../../../../arm-linux-gnueabihf/bin/ld: warning: libGLESv2.so.2, needed by /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Quick.so.5.15.2, not found (try using -rpath or -rpath-link) /opt/qt5pi/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/7.5.0/../../../../arm-linux-gnueabihf/bin/ld: warning: libpng16.so.16, needed by /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Gui.so.5.15.2, not found (try using -rpath or -rpath-link) /opt/qt5pi/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/7.5.0/../../../../arm-linux-gnueabihf/bin/ld: warning: libz.so.1, needed by /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Gui.so.5.15.2, not found (try using -rpath or -rpath-link) /opt/qt5pi/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/7.5.0/../../../../arm-linux-gnueabihf/bin/ld: warning: libharfbuzz.so.0, needed by /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Gui.so.5.15.2, not found (try using -rpath or -rpath-link) /opt/qt5pi/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/7.5.0/../../../../arm-linux-gnueabihf/bin/ld: warning: libdouble-conversion.so.1, needed by /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Core.so.5.15.2, not found (try using -rpath or -rpath-link) /opt/qt5pi/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/7.5.0/../../../../arm-linux-gnueabihf/bin/ld: warning: libicui18n.so.63, needed by /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Core.so.5.15.2, not found (try using -rpath or -rpath-link) /opt/qt5pi/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/7.5.0/../../../../arm-linux-gnueabihf/bin/ld: warning: libicuuc.so.63, needed by /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Core.so.5.15.2, not found (try using -rpath or -rpath-link) /opt/qt5pi/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/7.5.0/../../../../arm-linux-gnueabihf/bin/ld: warning: libicudata.so.63, needed by /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Core.so.5.15.2, not found (try using -rpath or -rpath-link) /opt/qt5pi/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/7.5.0/../../../../arm-linux-gnueabihf/bin/ld: warning: libpcre2-16.so.0, needed by /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Core.so.5.15.2, not found (try using -rpath or -rpath-link) /opt/qt5pi/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/7.5.0/../../../../arm-linux-gnueabihf/bin/ld: warning: libgthread-2.0.so.0, needed by /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Core.so.5.15.2, not found (try using -rpath or -rpath-link) /opt/qt5pi/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/7.5.0/../../../../arm-linux-gnueabihf/bin/ld: warning: libglib-2.0.so.0, needed by /opt/qt5pi/sysroot/usr/local/qt5pi/lib/libQt5Core.so.5.15.2, not found (try using -rpath or -rpath-link) FYI: I have followed https://github.com/PhysicsX/QTonRaspberryPi/blob/main/qt5.14.2onRaspberrypi tutorial for crosscompiling.

it worked for me, thanks a lot.. .

Thanks for the update. Marking this one as solved.

@Szymon-M-Sabat Interesting. Did you search in Fedora bug tracker (or whatever they have)?

@Sumaiya Depending on your needs, are you aware that Qt has Qt Test? Not much at Is there a open source automation tool for Qt app?.

Thank you. At least QStrings are shown correctly at the moment (Qt 5.15.2/Xcode 12.5). Don't forget to import the codecs together with the usual imports. import codecs Could not see any differences with the HandleCommand fixes.

I am wondering whether it's not something Designer specific. There's nothing in the code related to QRadioButton that would explain this.

So I came a little closer. Seems like I had QML-Debugging enabled in Projects -> Build -> QML debugging and profiling, which I was actually not interested in. I disabled it and then installed gdbserver on the device. I can now launch debug mode, but Valgrind still says Error reading debug symbols, plug I get a bunch of other error messages.

@eyllanesc Thank you that worked

@JonB https://www.qt.io/blog/qt-creator-5.0.1-released Someone pointed this problem out in the comments. and there has already been a bug report on this. Apparently the fix will be available in 5.0.2.
