build failed in "make -j8 && make pycaffe" step

[Geo-fortune]

I have build Caffe successfully before building the fast-rcnn.
My opencv version is 3.0.0 .
the Terminal shows the error below :

Add opencv_imgproc in your Makefile might help.

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

Try it without the -j8 flag and see if you still get the error.
