"SerialControl" - Linker error for Teensy 4.1 board

[asanjib28]

Hello! First of all, thanks a lot for the A quad B programs!! I needed a A quad B emulator which could generate pulse upto 1 MHz, and this solution would work well for me. However, I am facing a glitch when I try to compile the "SerialControl" code using Arduino IDE 2.0.4 for a Teensy 4.1 board. Please note that, I have not made any changes to your "SerialControl" code base. The error message is attached. Could you please help me with a suggestion on what I should do to get rid of this?
