make error(s)

[arghhahhs1j2rug82rbr2g]

Hey, I tried installing the code and I followed all the steps up to make but when I ran make it gave me the following errors.

❱ make
usage: grep [-abcDEFGHhIiJLlmnOoqRSsUVvwxZ] [-A num] [-B num] [-C[num]]
	[-e pattern] [-f file] [--binary-files=value] [--color=when]

objcopy -I ihex bin/dongle.ihx -O binary bin/dongle.bin
make: objcopy: No such file or directory
make: *** [dongle.bin] Error 1
❱ 

first off, grep -P doesn't work (or even exist)
second, I have no idea how make works because it says it ran test -lt and I don't see that in the makefile
and last it looks like it can't find obj copy or dongle.bin

Any help would be appreciated,
Thanks.
