@SGaist
yes all opencv files is included in the path.
After some research in log file, i think I have a problème with the génération of libopencv_imgcodecs310 and libopencv_imgproc310 files.
@mvuori yes i did check these solutions but i have no idea about these compiler directives. How do i use them in QtCreator. And it throws error for only one project and my other projects are working fine.
@SGaist Hi, nothing, it compiles ok and runs.
The only closest thing is a flaw in my fix, though just a warning
And when it crashes, nothing as far as I can tell or find.
