I have modified the caffe source code according to

Region of Interest pooling layer (ROIPooling). This is the same layer used by fast RCNN and faster RCNN. A C++ implementation can be found in BVLC/caffe#4163

But cannot succeed compilation. The error is showed in the following. Is there some modification of caffe code between my version (cloned in April,2019) and yours?
And how to run your test code of deep retrieval model At present.
