  Hello, I have the same problem as above: /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 3 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 4 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 5 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 6 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 7 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 8 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 9 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 10 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 11 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 12 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 13 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 14 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 15 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 16 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 17 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 3 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 4 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 5 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 6 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 7 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 8 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 9 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 10 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 11 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 12 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 13 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 14 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 15 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 16 (>= sh_info of 3) /usr/bin/ld: /home/user/Qt/5.12.6/gcc_64/lib/libQt5WebEngineCore.so.5.12.6: .dynsym local symbol at index 17 (>= sh_info of 3) This only happens on the first run after I have changed some code, every re-run of the same stage of code starts directly. The QtWebEngine is installed, I already tried to remove and reinstall it, but that does not help. Neither does another version of Qt help. It also is correctly linked in the kit-settings. I am pretty sure that it worked before I updated my version of Qt, therefore I don't think it is a problem with ubuntu 19.10. When I ignore this error my programm runs perfeclty fine, but it is pretty annoying to always click the 'proceed/ignore errors' button after each new build. I am thankful for any suggestions on how I can solve this problem. And sorry for kind of gravedigging this, but this was the most promising google hit. Edit: configuring the gold linker with the command: sudo ln -sf /usr/bin/x86_64-linux-gnu-ld.gold /usr/bin/ld found here: https://cristianadam.eu/20170709/speeding-up-cmake/ did the job, the errors are gone.

  @slawtul said in QtCreator dark themes unreadable: Hi the same problem on Fedora 31 KDE. I switched from default to Breeze Dark theme. I installed QtCreator and all menus were unreadable. However I changed QtCreator theme from Flat to Dark and I can see menu items now. Thank you. I'm not sure how I missed that setting. I appreciate your screenshot. I also found this theme I may try: Dracula — A dark theme for Qt Creator and 84+ apps https://draculatheme.com/qtcreator/ dracula/qtcreator: A dark theme for Qt Creator https://github.com/dracula/qtcreator

  @Himanshu-charde In fact in the case you show I think your process.start("literal string") will work OK, but only because it doesn't happen to have any special characters which need quoting. But @jsulm suggestion to use the separated string list arguments is more robust if that changes. The vital thing is that as @jsulm says you are not attempting to read any output from the process back into your Qt app. You'll want https://doc.qt.io/qt-5/qprocess.html#readAllStandardOutput and possibly https://doc.qt.io/qt-5/qprocess.html#readyReadStandardOutput. And while you are at it, always do the same for https://doc.qt.io/qt-5/qprocess.html#readAllStandardError. And the https://doc.qt.io/qt-5/qprocess.html#errorOccurred signal. People don't bother and then wonder what's happening when an error is reported....

  @Milosz said in Using Qt classes in VS project: n other words I have to create a new project - I cannot modify the current one. did i understand correctly? Perhaps you can try to use Qt Visual Studio Tools. It may include an import feature, but I don't know. I never use it. Yes, you need to create a new project, because using Qt requires to made deep changes in your code.

  Since these are two different build systems there are for sure different flags. If you need a specific flag you have to make sure it's there for both build systems. Both can create a running Qt application.

  the build error is following: I guess it's not supposed to be built in this way. Looks like I should build it as a new Qt module like described "here":http://qt-project.org/wiki/Creating-a-new-module-or-tool-for-Qt#55af8d3b581bc7a96ac2a08eb19da92c. Please correct me if I'm wrong.

  This topic is quite old, but for any future time-travelers coming by this way, I found a workaround, that works at least in my case. My projects is structured as a SUBDIRS project, with all the subprojects listed in the main .pro file. In each subproject file, I "include(PARENT_PROJECT.pro)", on the very first line. Moving this include statement to the bottom of the subproject's .pro file fixed the QtCreator syntax highlighting issue for me. Hopefully this helps someone, somewhere out there.

  Hi Did you also build the "LLVM/Clang 6.0.0 or newer for the Clang Code Model related plugins." it seems it crashes loading that. Its now default ON in newer creators. You could try to start it with -noload all so none of the plugins are loaded then go to About plugins and disable the codemodel and see if that makes crash go away.

  Hi, The IFW writes all files relative to the given base installation directory. One option might be that in the component's installscript.qs you move the files to desired destination directory. Note that here you need to take care of elevated permissions if needed and also implement the "undo" operation so that when you uninstall (MaintenanceTool(.exe)/Uninstaller(.exe)) the packages it knows what to uninstall. To make IFW natively support installing packages with absolute paths please open a Jira ticket/suggestion, I think it might make sense in such cases.

  @artwaw thanks for the suggestion. I'd tried a clean and run qmake (in that order) with no success. The missing step (for me, anyway) was the rebuild command.
