verilator: fails to compile "trace" output

[ragge0 (Anders Magnussoon)]

I tried to use the macports version of verilator to generate a trace file, but it complains about the system headers. Normal usage of verilator works just fine.

Macos 10.15.3 MacPorts 2.6.3

Here is the complete compilation output. The clang error is quite obvious, but I don't understand why it fails (I do not have deep enough knowledge about macos compilation environment).

-- R

verilator --trace -Wall -Mdir nvaxtracedir --prefix Vnvax -cc -y .. sbi.v
(cd nvaxtracedir; make -f Vnvax.mk)

In the future, please use WikiFormatting, fill in the Port field and add the port maintainer(s) to Cc (port info --maintainers verilator), if any.

I do not believe this is a verilator problem.
The code seems to require ​C++17.
