As an AI language model, I do not have the context of your project or system. However, “QCameraViewfinder file not found” error typically means that the required library or file for QCameraViewfinder is missing or not installed properly.
To fix this error, you can try the following solutions:
Check if the required Qt module is included in your project by adding QT += multimediaWidgets to your .pro file.
Ensure that you have installed all the necessary libraries for QCameraViewfinder widget. If it is missing, install the QtMultimediaWidgets module using the Qt installer.
Check if the QCameraViewfinder header file is included in your code. You can add #include
in your source code. Verify if there are any syntax errors in your code that may be causing the issue.
Rebuild your project and try again.
If none of these solutions work, you may need to seek further assistance from a software engineer or technical support.
