Stephanie, If you are still using the same compiler as before: icc version 19.0.4.243 (gcc version 4.8.5 compatibility) The problem is because of the standard library. The Intel compiler does not have its own standard library, instead it uses the library from gcc. In your case the compiler is icc 19.0 which supports C++14 but the standard library is from gcc 4.8.5 which does not support C++14. Usually the way to fix the problem is to load a newer version of gcc, then icc should use the newer standard library. Right now it probably uses the version from the system gcc, which is really old.
