To reproduce

arduino-cli core update-index
arduino-cli core install esp32:esp32@3.3.0-RC1
export BOARD=esp32:esp32:esp32c6
arduino-cli compile -v --build-path=/tmp/arduino -b "$BOARD" NimBLE-Arduino-2.3.2/examples/NimBLE_Client/NimBLE_Client.ino

Build for C5 gives the failure as well.
However, build for C3 is fine.

The failure is noticed with most recent 3.3.0-RC1
Build with previous 3.3.0-alpha1 is successful.

Looks like they have enabled the nimble stack by default now so this repo will no longer work with the new cores, sad day 😞.

Using esp-nimble-cpp may be an option, sadly though you will no longer be able to configure the build settings.
