Hi! I have no doubt how to install it on CentOS6.

@Dmitriyverkhov I don't know if you're still looking into this, but I got it building on CentOS 6 and 7 using CentOS Software Collections. https://www.softwarecollections.org/en/

yum -y install centos-release-scl && yum makecache
yum -y install devtoolset-7-gcc devtoolset-7-gcc-c++
scl enable devtoolset-7 bash
make && make install

The issue is that the system-provided gcc/g++ are much too old and don't understand some of newer syntax.
