Complie riscv-gnu-toolchain on MacOS Error

Question

I compile gnu-tool-chain on my Mac, and get some error message
I'm in the riscv-gnu-toolchain root directory, and

./configure --prefix=/usr/local/opt/riscv-gnu-toolchain
make

I get

...

      [-Werror,-Wimplicit-function-declaration]

make[3]: *** [rltty.o] Error 1
make[2]: *** [all-readline] Error 2
make[1]: *** [all] Error 2
make: *** [stamps/build-gdb-newlib] Error 2

My MacOS version is 10.15.7. Should I add some headers file in somewhere?
