Verilator plans to require a C++11 or newer compiler in a future release,

C++11 compiler, please post a message to
https://www.veripool.org/boards/3/topics/2580-Verilator-Requiring-C-11-compiler

configure with the --enable-prec11 argument. Thanks.]])
Verilator will require a C++11 or newer compiler for all releases starting
September 2020. Please investigate a C++11 build environment now so you
will be ready. Until then you may rerun configure with the
--enable-prec11-final argument to enable reduced functionality with such
older compilers. Thanks.]])
