    Well, my application is back to running. I got frustrated trying to strip down my application and decided to throw a couple of spitballs at the wall. Not for the first time, I deleted the pro.user file making sure some of the settings that were not included in the DummyMainWindow project. Re-opening the project after that and the project was once again running. I am not really sure what happened but I'm working again. So I am going to close this topic. Thanks for catching the typo...and for the "linguistic analysis" of the typo. LOL

    Hi again, in the meantime our clang experts are working on a solution for using lldb. I'm sure they will do it well. I still have another issue with lldb. But therefore I will start another thread or even create a bug ticket. And for the issue with gdb not showing the object member values (which was my original one) I first will try to find out, whether there is a new gdb version doing it better.

    Hello, you can have multiple executables in one CMake project, and deal with it in one single Qt Creator instance. As a template you can git clone "https://codereview.qt-project.org/qt/qtqa" and load .../src/fuzzgen/CMakeLists.txt in Qt Creator. It's a project with multiple executables. You can select the run target like that: [image: aa73058f-e72b-45f2-9e27-b532d2583f5e.png]

    Not that I want to discourage you but did you consider using Qt Multimedia ? It already provides support for playing music using ffmpeg under the hood. That said, did you already check the mpv C client api ?

    Hi, Which version of Qt Creator ? Which version of Qt ? On which OS ? Does it happen if you use a default project ? Is it a complex class ? Do you have a more complete error message ?

    I have similar issue, working on a fairly large project. When build completes and VS is about to launch a debug instance. The process freezes for 5-10 seconds. I'm also getting repeated warnings from Visual Studio that the extension caused VS to become unresponsive. Previous Qt Vs Tools version was working fine.

    A question: How is this integrated. Uses it the full codemodel for the project (I have 140000 LOC) or looks it only the corrosponding CPP-File what should be fast ? I will check the other hints.

    I never thought I'd have to add the current folder (.). That solved my issue indeed.

    @oldbrad said in Creator error but command line works.: The moral of this tail is you can NOT install over a Linux package manager installation. Glad you found a solution but the rule is: you shall not install a custom build of a library, whether Qt or another one, over a distribution provided one. You could break your system doing that. However, nothing should prevent them from being properly co-located and used independently by your application.

    You should at least mention that your problem is within QtCreator when you are not even able to post in the correct category...

    @berliner : It was fixed in https://codereview.qt-project.org/c/qt-creator/qt-creator/+/708134 commit. However, it went to Creator 19.0 so please try this version to verify whether it fixes your issue.

    Hi, I've solved this problem. In README.md, I found an extra step to install the documentation. I should've run these commands after installing Qt: cmake --build . --target docs sudo cmake --build . --target install_docs But, since I had deleted my qt-build and /opt/Qt6/examples, I did these following to make the examples, along with the documentation, accessible from within Qt Creator: mkdir qt-build && cd qt-build ~/qt-sources/configure -prefix /opt/Qt6 -skip qtwebengine -nomake tests -make examples -- -DQT_BUILD_EXAMPLES_BY_ DEFAULT=OFF -DQT_INSTALL_EXAMPLES_SOURCES=ON cmake --build . --parallel --target docs sudo cmake --install . --component examples_sources sudo cmake --build . --parallel --target install_docs After that, the examples and documentation are accessible from Qt Creator: [image: edb125fb-5997-469c-bdb2-f50239796b90.png] Screenshot of Examples [image: 5a9e5824-ab94-48fc-8351-7bb5b5ba89d8.png] Screenshot of Help

    And if you have Ninja installed via Qt SDK, you should have in your QtCreator.ini something like: [CMakeSpecificSettings] NinjaPath=/Users/cristian/Qt/Tools/Ninja//ninja which should get CMAKE_MAKE_PROGRAM set to this value.

    I found out that if I create a new project without any translation files, it opens the project normally. Then if I add a TRANSLATIONS section to the .pro file, I get the error described above. So it might have something to do with Qt Linguist? But I can use different AI models in Lnguist, not necessarily ollama?
