I’m new to QT and am having trouble setting up OpenCV for use with QT under OSX. Most of the information I’ve found on this pertains to Windows or Linux so I’m struggling. I’ve written an extensive post about what I have tried so far over at stackOverflow [stackoverflow.com] Rather than repost all that here, the gist is that I don’t seem to be linking to the OpenCV libs correctly. The console output is below.
I’ve tried various ways of specifying the lib path & libs in the project profile. OpenCV is correctly installed for OSX – the headers are at /usr/local/include and the libs at /usr/local/libs. Does QT require something different?
If more detail or specifics are needed, please let me know or check out my post at stackOverflow [stackoverflow.com]
- Thanks!
– one attempt at defining the lib paths. Tried it without periods, etc.
LIBS += -L/usr/local/lib \
-1ibopencv_core.2.4.6 \
-1ibopencv_imgproc.2.4.6 \
-1ibopencv_features2d.2.4.6 \
-1ibopencv_highgui.2.4.6
