Dear list,

I tried to load integer data from a Python .npy file by using RcppCNPy, 
while I tried to install RcppCNPy, I got the following error messages:
R> install.packages('RcppCNPy')

The downloaded source packages are in
Warning message:

My system specification:

glibc: 2.17 (Ubuntu package version: 2.17-0ubuntu4)
libstdc++6-4.7-dev (Ubuntu package version: 4.7.2-21ubuntu3)

It seems that this problem is caused by some function defined 
Does anyone have encountered similar problem ?
