Compilers / C++11 only or C++11 and C++14?

Hi!

Now I found it:

Moving to C++11 (again)

We (Ben, Aki, Rob, Daniel, Mike, Jonah) discussed this at the meeting today. We concluded that starting in April 2017, we could require a C++ compiler that supports C++14. In particular, the minimum g++ version we could require is 4.9. XCode’s default clang++ version supports more of the C++14 standard than g++ 4.9, so we’re ok with Mac. The reasoning is: R will release 3.4 in April. Starting with version 3.3, RTools has been using g++ 4.9. In April, R will no longer support 3.2, the last ve…

So the decision so far is to go with g++ 4.9.3 from Rtools. I am happy to put this on the open discussion points as I am not sure if RHEL was being considered.
