Error building Opencv4 with Qt5

On the photo, there is actually useful text. It was a windows cmd prompt terminal, I didn’t output the huge amount of logs to a file. The screenshot was convenient.

If it is an advice you are giving, I think there is a way to say it in a more friendly manner. In that case I would take it into account heartily.

(Anyway thanks for the quick reply).

After the changes the logs just changed from std::hypot to std::_hypot.

Right, it seems a 32 bit, I probably should have used the mingw810_64 tool.
I try that one, and come back to precise the new results.
