It compiles fine:

c++ -std=3Dc++11 -I/usr/local/include -L/usr/local/lib -lginac
C-src-1053hn1.cpp

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 t=
ool
that is as good as org-mode for literate programming and reproducible
research.  A big thank you to those who created and maintain it.

Cheers,

Good to know it is solved.
You can customize this variable:
=A0 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:
=A0 M-x debug-on-entry RET org-babel-eval RET
=A0=A0 evaluate the Babel block
The debugger shows a line like this one:
=A0 * org-babel-eval("g++ -o /tmp/babel-3110Zeg/C-bin-3110Fwh -std=3Dc++11 ...
This works for many languages supported by Babel.
