I'm getting:

Invalid MEX-file '/home/tiago/Documents/MATLAB/mexopencv/+cv/findChessboardCorners.mexa64': libopencv_calib3d.so.2.4: cannot open shared object file: No such file or directory.

even with:

LD_PRELOAD=/usr/lib/libstdc++.so.6 matlab

any idea of what's wrong?
I'm on Ubuntu 10.10, Matlab R2010b and opencv 2.4.3

Required shared object varies. Check you installed opencv in the standard path, such as /usr/local/, and you can load any shared objects in matlab. After that, use ldd to locate which library is failing. See #62

I found what was wrong!
I seems that I accidentally skipped one step at the end of OpenCV installation:

$ export LD_LIBRARY_PATH=/usr/local/lib

After this, everything went smooth
