Использовать OpenCV в функции mex: ошибка после компиляции

Я работаю над проектом, разработанным под Matlab, но мне пришлось использовать С++ и OpenCV. Чтобы интегрировать мою работу с проектом, мне нужно использовать mex файлы. Поэтому я установил Matlab 2013 на свой компьютер и gcc 4.4. Я изменил файл ~/.matlab/R2013a/mexopts.sh, чтобы установить правильный компилятор и параметры для opencv. Это результат компиляции в matlab с mex -v

  Warning: Neither -compatibleArrayDims nor -largeArrayDims is selected. 
           Using -compatibleArrayDims. In the future, MATLAB will require
           the use of -largeArrayDims and remove the -compatibleArrayDims
           option. For more information, see:

Но когда я пытаюсь использовать mxFunction как this mxFunction ('path_to_my_file'), результат:

Invalid MEX-file '/home/amine/Stage2A/stage2a/src/HypothesisGeneration/mxFunction.mexa64': /usr/local/lib/libopencv_ocl.so.2.4: undefined symbol:
_ZTIN2cv16ParallelLoopBodyE

Не могли бы вы помочь решить эту проблему?

PS: Я использую ubuntu 14.04 и Opencv 2.4.8
