During installation of matcaffe I get the following issue:

I am using gcc--4.6 compiler
Matlab R2014b
Ubuntu 14.04
Only CPU.


Any advice on how to rectify the issue??

I don't know about gcc-4.6, but with 4.7.3 I needed to enable c++11 support with

export CXXFLAGS="-std=c++11" ; make mat

cheers,
