• 安装Qemu

sudo apt updatesudo apt -y install qemu-user-binfmt qemu-user-static systemd-container
sudo apt -y install zstd

• 配置环境

RISCV_FILE=archriscv-2023-10-09.tar.zstwget -c http://mirrors.wsyu.edu.cn/archriscv/images/${RISCV_FILE}
mkdir archriscv
sudo tar -I zstd -xvf ${RISCV_FILE} -C archriscv

• 启动虚拟机

sudo systemd-nspawn -D ${HOME}/archriscv/ --machine archriscv

• 测试

# pacman -Syyu# uname -m
riscv64

• 安装gcc

pacman -Syyu g++
pacman -S vi jdk11-openjdk

• 代码

#include <stdio.h>int main(int argc, char *argv[])
{printf("Hello RISC-V!\n");return 0;
}

• 测试

# gcc hello.c -o hello# file hello
hello: ELF 64-bit LSB pie executable, UCB RISC-V, RVC, double-float ABI, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-riscv64-lp64d.so.1, BuildID[sha1]=ca19bb1cab6f06c75002e1a6e0cde25c12432355, for GNU/Linux 4.15.0, not stripped# ./hello
