can't build the python wrapper with make pycaffe

[helxsz]

I have compiled and built the caffe through the cmake, and it is working well for the example - imagenet, which I can train the CNN network and get the model. Now I want to use the model to classify, the classification example - http:https://nbviewer.ipython.org/github/BVLC/caffe/blob/master/examples/classification.ipynb is given in the python example. so I need to have a python wrapper built as well.
According to the python instruction, use
make pycaffe
so I also downloaded the cudnn6.5 library, and place cudnn.h into /usr/include. and I tried to make all , the error of 'cannot find cudnn.h' is gone.
But more errors come out

./include/caffe/util/cudnn.hpp:11:28: note: in definition of macro ‘CUDNN_CHECK’
     cudnnStatus_t status = condition; \
                            ^

Anyone experience the similar problem ?

Install cuDNN R1 instead of the R2 release candidate which is still experimental. See #1731 for an in-progress R2 branch.
