Hi,
I have the very same problem of @gerrywalsh when executing the line:
eval(['mex lk.cpp -O' include lib]);
However, if I run the command with the -c option (which means "Compiles an object file only. Does not build a binary MEX file.") compilation end successfully (but then "run_TLD.m" fails with "Undefined function or variable 'lk' since the associated mex does not exist I believe" )
I tried also to link to version 2.4 of opencv but the same error occurs.
Thanks
Hi there. I'm trying to run the TLD algorithm on Ubuntu 16.04 (64-bit) and MatLAB R2016b
I have not installed openCV, but rather the libraries as stated in the installation guide by
sudo apt-get install libcv-dev
When running compile.m from within MatLAB I get the error (s)

I have implemented the changes to the files as in Schloegl's pull request and thought this would sort out the error (s) I thought there were between linking MatLAB and OpenCV's libraries
Thanks Gerard
