Problem with OpenCV after updates to 4.0.1

shav

Hi everyone!

I'm updated the OpenCV on my Mac with brew to 4.0.1 version and now when I'm build my project I'm receiving this error:

Library not loaded: /usr/local/opt/opencv/lib/libopencv_stitching.3.4.dylib
  Referenced from: /Volumes/HPDD/Applications/Qt/Qt5.x/5.12.0/clang_64/qml/ShavComponents/libShavComponents_debug.dylib
  Reason: image not found)

When I saw this error in first time I'm checked the path and didn't find the library and this is correct because I'm updated OpenCV to 4.0.1. My question is how I can set version of OpenCV if my integration in pro file looks like this:

QT_CONFIG -= no-pkg-config
CONFIG += link_pkgconfig
PKGCONFIG += opencv4
INCLUDEPATH += /usr/local/Cellar/opencv/4.0.1/include/

By the way, my project is building correctly but can not start because library which my application trying load doesn't exists. How I can fix this?

Hi,

Try adding the DYLD_LIBRARY_PATH environment variable to the Run part of the Project panel.
Put /usr/local/opt/opencv/lib/ as its value.

You can also run otool -L /usr/local/opt/opencv/lib/libopencv_stitching.3.4.dylib and compare the output of the same call to the equivalent library of OpenCV 3.
