I just build the latest version of boost (1.64)

I tried running the following code: http://ideone.com/n6FSKr

It didn't compile and instead gave the following error: https://usercontent.irccloud-cdn.com/file/Pf0b8F8L/Screenshot%20from%202017-05-22%2012-37-43.png

Can someone please help in understanding and rectifying it. 

Thanks in advance, 

Best Regards,
