python - undefined symbol: _ZN2cv3Mat10deallocateEv -

-

i've been trying extend python script c++ code. able simple libraries of c++ (print "hello world"). followed tutorial available in link below:

http://www.tutorialspoint.com/python/python_further_extensions.htm

when tried add c++ code opencv libraries encountered following problem: importerror: /usr/local/lib/python2.7/dist-packages/kalman.so: undefined symbol: _zn2cv3mat10deallocateev

i searched many solutions on internet, , found 1 common answer didn't workout me: "i able solve going /usr/lib64/pkgconfig , modified opencv.pc explicitly have libraries. had move plugins /usr/lib/gstreamer-0.10 /usr/lib64/gstreamer-0.10"

please note using ubuntu 14.04 lts 64-bit , planning run code later on on raspberry pi model b running raspbian os.

thank you.

check shared library kalman.so ldd so:

 $ ldd kalman.so

and see missing libraries. means have provide correct path 1 of libraries use in code @ linkage stage. like

 $ ...the way linking ... -l path_to_the_missing_library

for more information, please, consult link.
