Cant load images after adding opencv_face450.dll.a libraries

edit

but i soon as i add the opencv_face450.dll.a library to the project, the imread function stops working

this sounds quite unlikely. you probably added some code to detect landmarks, which breaks your program.

please show us, what you have, so we can take a look at it

I am using eclipse CDT 7.0, opencv 4.4

Ok i am trying to uncomment the code step by step to see why it fails

again, show , what you have, please
