Bug Description

Hello! I'm trying to setup CVA6 environment and I cannot run the script correctly. I followed the README and installed riscv-gnu-toolchain, then I ran ./verif/regress/smoke-tests.sh but failed. Here's the error message:

I also tried to run the command make verilate, and it seems that my g++ don't support C++17, but my g++ version is g++-11.

OK. I tried many versions of Verilator and somehow fixed this problem. Thanks anyway!
