Ubuntu 15.04
Opencv 3.0.0
Matlab R2014a

I downloaded opentld source from here and modify 'include', and 'libpath'
and also comment out ifdef _CHAR16T ....
and I got and error like this,,

Unix

오류 발생: compile (line 77)
eval(['mex lk.cpp -O' include lib]);

so I hope to know what is the problem.
Thank you.
