Compiling .pio/build/pico/src/i2c_tiny_usb_adapter.ino.cpp.o
What happened ?
The way tud_vendor_control_xfer_cb is linked in Adafruit_USBD_WebUSB.cpp causes runtime-only errors that are remarkably hard to track down, as they cause no compilation hiccups.
Emptying src/arduino/webusb/Adafruit_USBD_WebUSB.* is a workaround.
This platformio thread recomended trying lib_archive = false, which didn't work for me
or using extern "C" {...} around the tud_vendor_control_xfer_cb function, which also didn't work, I think because the function is a class member?
How to reproduce ?
Try to compile the i2c example in platformio.
