Espidf-arduino-blink example fails to build...again?

Using the@maxgerhardt example from

fails with this error:

c:/users/peter/.platformio/packages/toolchain-xtensa32@2.80200.200827/bin/…/lib/gcc/xtensa-esp32-elf/8.2.0/…/…/…/…/xtensa-esp32-elf/bin/ld.exe: cannot find -lUsersPeter.platformiopackagesframework-espidf@3.40001.200521componentsxtensaesp32libhal

platform.ini is unmodified from the example.

does anyone have an example arduino-espidf that currently works?

OK, after much thrashing about, this appear to be some kind of tool chain corruption. I mostly fixed the issue by uninstalling PIO from VSCode and deleting the .platformio directory and then reinstalling PIO. (OS is Win 10)

so now example blink builds as well as my own arduino-esp32 code but i do get an “error” in installing windows-curses. Is windows-curses required??
