This is a warning, but the project is being compiled with -Werror which causes the compiler to treats warnings as errors. To get around this, open util/c.make and make the below change to ignore all warnings:

-CFLAGS += -Wall -Wextra -Werror -Wno-unused-parameter
+CFLAGS += -w

better to just disable that one warning though:

CFLAGS += -Wall -Wextra -Werror -Wno-unused-parameter -Wno-stringop-overflow
