undefined reference to `_Z13__USBHIDReadyv'

[Mons1ter]

When compiling, it displays "C:\Users\admin\AppData\Local\Arduino15\packages\rp2040\hardware\rp2040\3.6.0\libraries\Keyboard\src/Keyboard.cpp:43: undefined reference to `_Z13__USBHIDReadyv'", But the code ""_Z13__USBHIDReadyv" was not found in the source code.

It is error: c:/users/admin/appdata/local/arduino15/packages/rp2040/tools/pqt-gcc/2.1.0-a-d3d2e6b/bin/../lib/gcc/arm-none-eabi/12.3.0/../../../../arm-none-eabi/bin/ld.exe: C:\Users\admin\AppData\Local\Temp\arduino\sketches\08CF636668B5462CB34EDB6061AA0222\libraries\Keyboard\Keyboard.cpp.o: in function tud_hid_set_report_cb': C:\Users\admin\AppData\Local\Arduino15\packages\rp2040\hardware\rp2040\3.6.0\libraries\Keyboard\src/Keyboard.cpp:59: multiple definition oftud_hid_set_report_cb'; C:\Users\admin\AppData\Local\Temp\arduino\sketches\08CF636668B5462CB34EDB6061AA0222\libraries\Adafruit_TinyUSB_Library\arduino\hid\Adafruit_USBD_HID.cpp.o:c:\Users\admin\Documents\Arduino\libraries\Adafruit_TinyUSB_Library\src\arduino\hid/Adafruit_USBD_HID.cpp:243: first defined here c:/users/admin/appdata/local/arduino15/packages/rp2040/tools/pqt-gcc/2.1.0-a-d3d2e6b/bin/../lib/gcc/arm-none-eabi/12.3.0/../../../../arm-none-eabi/bin/ld.exe: C:\Users\admin\AppData\Local\Temp\arduino\sketches\08CF636668B5462CB34EDB6061AA0222\libraries\Keyboard\Keyboard.cpp.o: in function _ZN9Keyboard_18sendConsumerReportEt': C:\Users\admin\AppData\Local\Arduino15\packages\rp2040\hardware\rp2040\3.6.0\libraries\Keyboard\src/Keyboard.cpp:52: undefined reference to_Z13__USBHIDReadyv' c:/users/admin/appdata/local/arduino15/packages/rp2040/tools/pqt-gcc/2.1.0-a-d3d2e6b/bin/../lib/gcc/arm-none-eabi/12.3.0/../../../../arm-none-eabi/bin/ld.exe: C:\Users\admin\AppData\Local\Temp\arduino\sketches\08CF636668B5462CB34EDB6061AA0222\libraries\Keyboard\Keyboard.cpp.o: in function _ZN9Keyboard_10sendReportEP9KeyReport': C:\Users\admin\AppData\Local\Arduino15\packages\rp2040\hardware\rp2040\3.6.0\libraries\Keyboard\src/Keyboard.cpp:43: undefined reference to_Z13__USBHIDReadyv' collect2.exe: error: ld returned 1 exit status Multiple libraries were found for "Adafruit_TinyUSB.h" Used: C:\Users\admin\Documents\Arduino\libraries\Adafruit_TinyUSB_Library Not used: C:\Users\admin\AppData\Local\Arduino15\packages\rp2040\hardware\rp2040\3.6.0\libraries\Adafruit_TinyUSB_Arduino exit status 1

Install the Pi Pico/RP2040 board version 2.7.3 and the code should compile. Something broke starting with version 3 of the RP2040 board library and I haven't fixed it yet.

This issue is now officially fixed. The project builds with the latest Arduino-Pico version 3.9.0.
