Beginners • undefined reference to `wiringPiSetupGpio'　

After purchasing Raspberrypi4B and installing it, I created a sample program and built it.
A link error will occur.

This is a basic link error, but please provide a solution or any helpful comments.

gcc -Wall -I/usr/local/include -I/usr/include -IwiringPi -lpthread -lcrypt -lm -L/usr/lib,/usr/local/lib,/usr/lib/aarch64-linux-gnu -o hssprg001 hssprg001.o

/usr/bin/ld: hssprg001.o: in function `main':

Thank you.
