问题
I am using Ubuntu and am trying to use Octave to run a Matlab script that runs the mex compiler on some cpp files https://github.com/yuxng/MDP_Tracking/blob/master/compile.m I have the OpenCV requirement already installed but am receiving some errors.
Basically the commands in octave are
compile
MOT_test
The errrors I got from the compile command are shown below. Based on my google search plus this thread Mex file building with Octave (issue with wrappers) it seems like this issue of compiling the MDP Tracker remains unsolved. I have minutes of experience running mex and octave so there is not much that I can do other than ask. I hope to get some help here. Thanks !
