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:
Error using cv.imread Invalid MEX-file '/tmp/+cv/imread.mexa64': /usr/local/lib/libopencv_highgui.so.2.4: undefined symbol: _ZNK9QCheckBox15minimumSizeHintEv

recently I was having the same problem. Just set up the LD_LIBRARY_PATH as
environment variable, to the directory containing your opencv libraries (i
put it in the .bashrc). then restart you matlab. It should solve it.

hmm, doesn't help.
I found this link but it didn't help since I have all qt libraries installed.

what's the best way to debug this?

Compare the output of ldd on the MEX-file both run from inside MATLAB and on the system shell (similar to #62).

Take note of the Qt libraries. If there is a mismatch, try using LD_LIBRARY_PATH and/or LD_PRELOAD tricks

Problem goes away using the correct preloading:

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libQtCore.so:/usr/lib/x86_64-linux-gnu/libQtGui.so:/usr/lib/x86_64-linux-gnu/libQtOpenGL.so /usr/local/bin/matlab-2012b
