Invalid MEX-file on Ubuntu 12.04 #64
Description
I get an invalid mex-file error but all my libraries are ok:
Example nbr 1:
run:
detector = cv.CascadeClassifier('haarcascade_frontalface_alt.xml');
output:
`Invalid MEX-file '/tmp/+cv/private/CascadeClassifier_.mexa64': /usr/local/lib/libopencv_highgui.so.2.4: undefined symbol:
_ZNK9QCheckBox15minimumSizeHintEv``
Example nbr 2:
run:
cv.imread
output:
