Thanks for your quick response!
Compiled successfully when I switched to tag 9.4.116 and added an #include
<utility> in include/cppgc/allocation.h.
But it shows error during the link stage:
Undefined symbols for architecture arm64:
"v8::internal::trap_handler::RegisterDefaultTrapHandler()",
referenced from:
v8::internal::trap_handler::EnableTrapHandler(bool) in
libv8_monolith.a(handler-outside.o)

__siginfo*, void*)", referenced from:

ld: symbol(s) not found for architecture arm64
