build error

caffe-action building failed on my PC (Ubuntu16.04, cuda-8.0, cudnn-7), the error log is as follows:

it seems to be caused by the conflict between opencv and cuda-8.0... If I use the system-default opencv (installed by 'sudo apt-get install python-opencv'), I can successfully pass the caffe-action build. But in test phase, I will get another error: Error parsing text-format caffe.NetParameter: 19:12: Message type "caffe.LayerParameter" has no field named "bn_param". Do you have any suggested solution?

p.s. Thanks for your outstanding contribution in video recognition field!

problem resolved by building static library i.e. libprotobuf.a from the source code of protobuf and change the cmake configurations when building opencv and caffe.

besides, caffe.LayerParameter has no field named "bn_param" is caused by that I installed another version of caffe i.e. caffe-latest-master, and the default PYTHONPATH is set as 'caffe-latest-master/python'. it can be solved by python package-management.

Thanks for posting your solution.
