Weird linker error linking to opencv... "LNK1107: invalid or corrupt file: cannot read at 0x2E8"

Question

This OpenCV build was working for me a few nights ago. I am trying to run the example grabcut.cpp file given with the OpenCV examples and so I set up a quick project and brough the cpp file in. Then, I set up all of the standard configurations and got this error on building.

error LNK1107: invalid or corrupt file: cannot read at 0x2E8   
opencv_calib3d231.dll

What does this mean?

Answer 1

If I would have to guess (partially based on the documentation of that error), I'd say you're trying to link directly against the DLL.

You probably want to link against its corresponding .lib file.
