Public bug reported:
I am trying to build https://github.com/sthalik/headtracker
but when it comes to linking I am getting the following error:
/usr/bin/ld: /usr/lib/x86_64-linux-gnu/libopencv_objdetect.so.2.4.8: undefined
reference to symbol 'cvResize'
/usr/lib/x86_64-linux-gnu/libopencv_imgproc.so.2.4.8: error adding symbols: DSO
missing from command line
collect2: error: ld returned 1 exit status
make[2]: *** [headtracker-ftnoir] Error 1
make[1]: *** [CMakeFiles/headtracker-ftnoir.dir/all] Error 2
make: *** [all] Error 2
I have tried uninstalling/purging and reinstalling opencv. The author of
the software suggested it may be conflicting versions of opencv, but I
can't see any sign of that on my system.
This is the cmake link.txt file:
