Hello,
I’ve been having reoccurring troubles with root6 on my Mac. I’ve tried to install it both from source and binary without success. I have a root-60416 installed which was working previously but not anymore for some reason, and the problem is
input_line_1:1:10: fatal error: 'new' file not found
#include <new>
^
input_line_3:38:10: fatal error: 'string' file not found
#include <string>
^
input_line_8:1:10: fatal error: 'iostream' file not found
#include <iostream>
I’m fairly sure this is due to some C++ standard library mismatches. Because when I try to reinstall root with cmake and do “cmake …/root-6.04.16/ -Droofit:string=ON” I get early on that it finds clang 7.3.0 but further down it lists 3.7.0

[...]When I then do “cmake --build .” it starts to build, with a lot of warning about "redundant move"s, up until 34% where I get

This looks a lot like what is described here Embedded cling error with latest xcode, but I have the latest Xcode, installed after my recent upgrade to El Capitan:
edvinsidebo@eduroam-55-254:~/root60416-ElCapitan$ xcode-select -version
xcode-select version 2343.
edvinsidebo@eduroam-55-254:~/root60416-ElCapitan$ xcodebuild -version
Xcode 7.3
Build version 7D175
Could someone hint at a solution? This is becoming annoying as I also failed to install it via homebrew, so I’m quite stuck.
