MATLAB: MEX cannot find library ‘m’ specified with the -l option

i am using matlab2017b

mex -O -I/usr/include/opencv -lcxcore -lcv -lhighgui -c seeds2.cpp
mex -O mexSEEDS.cpp -I/usr/include/opencv -lcxcore -lcv -lhighgui seeds2.o
i am getting error in this file MEX cannot find library 'cxcore' specified with the -l option. MEX looks for a file with one of the names: libcxcore.lib cxcore.lib Please specify the path to this library with the -L option.
can you help me to solved this error? my opencv folder in c drive in download "C:\Users\Admin\Downloads\opencv" can you help to write path of opencv?

Best Answer

I assume you're following some instructions in order to compile some mex library. Clearly, from the format of the paths the instructions you're following are for a Linux OS, whereas you're on Windows.
Find the instruction for Windows. Possibly this may work:
mex -O '-LC:\Users\Admin\Downloads\opencv' -lcxcore -lcv -lhighgui -c seeds2.cpp
mex -O mexSEEDS.cpp '-IC:\Users\Admin\Downloads\opencv' -lcxcore -lcv -lhighgui seeds2.o
