Issues on Cygwin

sorry for having so many questions for today~

but i do need a help on cygwin.

i've tried to install crunch on cygwin but it shows this to me.

User@User-PC ~/crunch-3.6

$ make

Building binary...

/usr/bin/gcc -pthread -Wall -pedantic -std=c99 undefined crunch.c -lm -o crunch

gcc: error: undefined: No such file or directory

Makefile:74: recipe for target 'crunch' failed

make: * crunch Error 1

is there anyone could teach me on how do i solve it?
