=== Compiler Version and C++11 === Compiler Version and C++11
Verilator supports GCC 4.4.7 and newer. GCC 4.4.7 does not support C++11, Verilator requires C++11. Verilator does not require any newer versions,
therefore C++11 is generally not required. Exceptions may be made to but is maintained to build successfully with C++14/C++17/C++20.
require C++11 for features that are only practical with C++11,
e.g. threads.
