#2660: create autoconf test that checks for too old g++ STL in combination with icpc
Reporter: Roland Haas Status: new Milestone: Version: Type: task Priority: minor Component:
Compilation of the ET on clusters regularly fails if icpc is combined with a too old STL from g++. As of [https://www.einsteintoolkit.org/about/releases/ET%5C_2022%5C_05%5C_announcem...) the ET must be compiled with STL from gcc-6 (or later) when using icpc to provide for full C++11 support (and not technical preview C++11).
Similarly before, using gcc-4.3 (default on some redhat systems) will fail to compile vectors due to bad default constructors.
We should construct an autoconf test that tests for these issues and reports a useful error message to users setting up Cactus / the ET on their cluster. Note that technically Cactus would work with older C++ compilers but the Einstein Toolkit will not.
