Update to Flatbuffers 1.12.0 to resolve this problem. In addition when building flatbuffers specify -fPIC CXX flag to allow the libraries to be used in our shared objects.

This appears to be incomatible with Caffe. Building results in missing definitions of "CV_LOAD_IMAGE_COLOR". When building Caffe to use with ArmNN you can disable OpenCV. In the Makefile.config uncomment "# USE_OPENCV := 0". -- cgit v1.2.1
