Answer 1

This usually happens when you have either forgotten to uncomment line number 21(in my case) when you have opencv3 or if you have not checked the version properly.If opencv>=3.0 then in the makefile on line 181(in my case) add libraries like

LIBRARIES += glog gflags protobuf leveldb snappy \
  lmdb boost_system hdf5_hl hdf5 \
  opencv_core opencv_highgui opencv_imgproc opencv_imgcodecs

And also make sure to rebuild.
