After successfully building caffe with cmake.Problems about making matcaffe in root dir.

[Alan Teng]

config:

ubuntu 16.04

gcc g++ 5.4.0

protobuf 2.6.0 

cmake 3.5.1

Caffe has been built with cmake, but when I try to make matcaffe in the root dir (I'm not sure it's right ). Some probelms arise, I guess it is the path of protobuf causing those error. Does some one can help me out? 

I've upload some details.

AR -o .build_release/lib/libcaffe.a

Insert a row

CXXFLAGS += -std=c++11

to your Makefile.config and retry. It works for me. Hope it helps.

I don't think MATLAB mex compiler support gcc > 4. See Supported and Compatible Compilers.
