$ export CC=clang CXX=clang++ CXXFLAGS=-stdlib=libc++
$ meson setup _build
$ meson compile -C _build

It doesn't help with assigning to .. from incompatible type ... or cannot initialize a variable of type ... with an rvalue of type ....

these functions are copied from xdpw, so whatever compile args they use should work here too.

xdpw is built by C compiler, not C++.
