So a little more progress on this one. Turning on C++ Exception support for the PicoW:nsh build configuration generates errors:
CC: pthread/pthread_testcancel.c machine/arm/gnu_unwind_find_exidx.c:32:8: error: unknown type name '__EIT_entry' 32 | static __EIT_entry *__exidx_start_elf; | ^~~~~~~~~~~ Configuration is: - C++ enabled - uCLib++ library - GNU low level support - Exceptions enabled. Turning exceptions off gives me missing symbols, guess that is going to be a missing library in the link phase.
