Use LD_PRELOAD instead.

I'm having this error while using cv.findChessboardCorners:

I've tried to run matlab as:
LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/libstdc++.so.6 matlab
but I got the same result...

I'm able to use some other mexopencv functions but not this one.
I'm on Ubuntu 12.04 LTS and running MATLAB r2012b

It worked!
Thanks a lot.

If anyone have this problem and using LD_PRELOAD worked as well, it may be useful to change the matlab shortcut (matlab.desktop) adding a line like:

LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/libstdc++.so.6

if you don't know where is libstdc++.so.6, just write on the terminal:

locate libstdc++.so.6

You can also link to the correct libstdc++ library and replace the one in Matlab's installation directory.

and I also has use:

sudo ln -sf /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.19 /usr/local/MATLAB/R2011a/bin/glnxa64/libstdc++.so.6

than solve the problem, but unfortunately, when I running run_cifar10, it running to：
