Running on FreeBSD 10.3, which uses clang/clang++ by default.  That
said, I _do_ have gcc 5.4.0 installed and accessible as gcc/g++, so I
don't know why it did not work.

Cheers,

All very good info, but why did the OP not have a g++?  Using a
non-linux operating system? Using a non-GNU tool chain? Inquiring
minds want to know...

I don't recall having had to do this before.

Phew! Very glad to have this working again.  I'm not aware of any other tool
that is as good as org-mode for literate programming and reproducible

Good to know it is solved.
You can customize this variable:
  C-h v org-babel-C++-compiler

In case someone else bump into a similar problem, the actual command
launched by Babel can be obtained through the debugger:
  M-x debug-on-entry RET org-babel-eval

RET
   evaluate the Babel block
The debugger shows a line like this one:
  * org-babel-eval("g++ -o /tmp/babel-3110Zeg/C-bin-3110Fwh
-std=c++11 ...
This works for many languages supported by Babel.

Solved by setting:

(setq org-babel-C++-compiler "c++")

I don't recall having had to do this before.

Phew! Very glad to have this working again.  I'm not aware of any other tool
that is as good as org-mode for literate programming and reproducible
research.  A big thank you to those who created and maintain it.
