[Openmp-dev] ld too old?

[Jeff Hammond via Openmp-dev]

Please response on the list.

You'll have to look at the Clang docs for minimum compiler versions but I
think this is a library issue and perhaps can be solved by setting
-std=c++11 or perhaps the ABI preprocess macro (
https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html).
