'Mex Configuration in MATLAB for OpticalFlow.cpp code

Hello, I am using the Optical Flow Matlab/C++ Code (source code). I am using MATLAB under a Linux-Ubuntu 14.04 64-bit OS. In the configuration file it says:

Before compiling, please check project.h file in subfolder "mex". You don't have to do anything if you use Windows. If you use Mac Os or Linux, please uncomment the line #define _LINUX_MAC.

This has been done. Also it follows:

In Matlab, after you configure mex appropriately, change directory to "mex" and run the following command:

mex Coarse2FineTwoFrames.cpp OpticalFlow.cpp GaussianPyramid.cpp

I think becuase of failing to properly configure mex compilerin MATLAB, I recieve the following error after running the above mex-command:

How can I solve this problem please?

Solution 1:[1]

I also face this problem when using OpticalFlow in MATLAB on a Linux server. I solve this by adding an option -compatibleArrayDims,

mex -compatibleArrayDims Coarse2FineTwoFrames.cpp OpticalFlow.cpp GaussianPyramid.cpp
