opencv fault

[pczebra]

when i compile ShapePFCN, after the "make -j32" command, it returns the following error

/usr/bin/ld: warning: libopencv_core.so.3.4, needed by ./caffe-ours/build/lib/libcaffe.so, may conflict with libopencv_core.so.2.4
/usr/bin/ld: build_release/./MeshProcessor.o: undefined reference to symbol '_ZN2cv6String10deallocateEv'
//usr/local/lib/libopencv_core.so.3.4: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
Makefile:156: recipe for target 'build_release/mvfcn.bin' failed
make: *** [build_release/mvfcn.bin] Error 1

what should i do to solve it ?

thank you for your attention!

Did you solve this problem?

[viralbthakar]

Incase anyone faces this error, here is the solution. This error suggest that it is not able to find OpenCV Library files. I have modifiers Makefile (Not Makefile.config) and added following path

CV_LIB_PATH := /usr/local/lib/

and the append the CV_LIB_PATH to LIBRARY_DIRS using

LIBRARY_DIRS += $(CV_LIB_PATH)

FYI
I have built Caffe using OpenCV 3.
