When compiled with:
-std=c++11
the simple hello_world.cpp:
#include <iostream>
int main()
{
std::cout<<"hello World\n";
return 0;
}
runs OK; however, with:
-std=c++1y
it gives error:
clang++ -std=c++1y hello_world.cpp -o hello_world.exe

How do I get right iostream for -std=c++1y.
I used default configure (except I specified--enable-optimized).
I'm running on ubuntu 14.04:
evansl@lje-OptiPlex-9020:~/dwnlds/llvm/git/build/release/object$ uname -a
Linux lje-OptiPlex-9020 3.13.0-30-generic #54-Ubuntu SMP Mon Jun 9
22:45:01 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
and followed instruction on:
http://llvm.org/docs/GettingStarted.html#git-mirror
What should I do to get hello_world to compile & run?
-regards,
Larry
