When i execute make i get this error:

mkdir -p target
cc -Wall -g -o target/client -pthread -lm -lbsd -O3 -std=gnu11 client/main.c

For Debian, it requires libbsd-dev.

Ah, yes, this is because of the use of arc4random in client/main.c. If someone wants to submit a PR replacing it with some other good (and thread-safe) source of randomness, I'd consider merging it to get rid of this dependency.

@xekoukou im using libbsd-dev, but still give this error.
