#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\_2022\_05\_announcement.h… 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. -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2660/create-autoconf-t…
