configure failure on g++14 (due to Fedora not providing it by default)
Installation on fedora 30 fails during configure with error message "A compiler with support for C++14 language features is required." GCC version 9.2.1-1 is installed and capable of providing requested feature. However, out-of-box install doesn't include this feature. Work-around run "g++ -v" and follow the prompts to update GCC.
