opencv:imread error

Hello,

I am trying to run a LINUX system executable code from MATLAB's cmd window using system command. The executable is created by making a simple c++ code reading and writing an image using OpenCV, but unfortunately I get this error (./MeshStereo is the executable)-

./MeshStereo: symbol lookup error: ./MeshStereo: undefined symbol: ZN2cv6imreadERKNSt7_cxx1112basic_stringIcSt11char_traitsIcESaIcEEEi

This error comes up on R2016a, but surprisingly not on R2017a. Can somebody please help me with resolving this error?

Thanks so much!

cv::imread(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int)

is the expanded name for that routine. Possibly the executable is not linked against libcv or libcv is not on LD_LIBRARY_PATH

Dear Walter,

Thanks for your response. The executable works well if I run it from a bash terminal, but fails with the mentioned error when executed from matlab's command line. Do you think it removes the first suspicion?

Thanks!

You are having LD_LIBRARY_PATH (Mac) or DYLD_LIBRARY_PATH problems. Does it happen to be the case that you are using High Sierra or Sierra? Apple made some security changes to LD_LIBRARY_PATH

Dear Walter,

Sorry I am not that familiar with this. I am running my code on Ubuntu16.04 release. If you can guide me, I will be happy to provide you any further information. Thanks!
