# we assume that the utilities from RISC-V cross-compiler (i.e., riscv64-unknown-elf-gcc and etc.)
# are in your system PATH. To check if your environment satisfies this requirement, simple use
# `which` command as follows:
# $ which riscv64-unknown-elf-gcc
# if you have an output path, your environment satisfy our requirement.
