    @rajatdongre79 Please show the actual error "Error 2" is not the error. In QtCreator open the "Compile Output" tab at the bottom to see the error message copy/paste it here.

    Start your application with the QT_DEBUG_PLUGINS environment variable set to one to see exactly what happens with the plugin.

    I went back to QT Online Installer 4.5.2 and everything is working fine. It seems there is a bug in version 4.6.0.

    @Piotrek102 From the Qt Open Source Development page: When selecting an open source license for your project, you contribute to free and open source software development by using Qt under any of the following licenses: LGPL version 3, GPL version 2 and GPL version 3. Please note that there are parts of Qt that are only provided under GPL for open source users that will require you to license your application under a GPL compatible license. Since you are using Charts, which is licensed under GPLv3, the GPLv3 license is the correct one for your project. As for the LGPLv2.1 and MIT licenses, those are GPL compatible.. For the installer, it is recommended to add a disclaimer of warranty and a limitation of liability clause similar to sections 15-17 of the GPLv3 to the installer that the user has to accept to install your program.

    @YogeshR Open a command prompt in the directory of the installer .exe and type: qt-unified-windows-x64-4.6.0-online.exe --mirror https://qt.mirror.constant.com/ or use 1 of the other mirrors at: https://download.qt.io/online/qtsdkrepository/windows_x86/root/qt/Updates.xml.mirrorlist Only use the first part of the mirror link before online/

    @quan-wei-jun Check in Creator's kits where it has picked up its gcc (or g++) from. Maybe you have multiple versions of gcc installed, and you need to pick the right one?

    Hi and welcome to devnet, You should rather use CMake to manage your C++ project and the corresponding VSCode integration.

    @jsulm looks like a wider issue. I would check the bug report system and open a ticket.
