手写操作系统篇：环境配置

前言

这篇博客先配置好我们之后的开发环境，下载一些依赖的软件包
建议大家使用ubuntu操作系统

C环境配置

sudo apt-get update && sudo apt-get upgrade
sudo apt-get install git wget build-essential gdb-multiarch qemu-system-misc gcc-riscv64-linux-gnu binutils-riscv64-linux-gnu

Rust环境配置

首先是Rust基本环境配置
https://blog.csdn.net/qq_67733273/article/details/133927336
这里就不再赘述

设置Rust为缺省版本，并安装一些软件包

rustup install nightly
rustup default nightly
rustup target add riscv64gc-unknown-none-elf
cargo install cargo-binutils
rustup component add llvm-tools-preview
rustup component add rust-src

Qemu安装

sudo apt install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev \gawk build-essential bison flex texinfo gperf libtool patchutils bc \zlib1g-dev libexpat-dev pkg-config  libglib2.0-dev libpixman-1-dev libsdl2-dev \git tmux python3 python3-pip ninja-build
wget https://download.qemu.org/qemu-7.0.0.tar.xz
tar xvJf qemu-7.0.0.tar.xz
cd qemu-7.0.0
./configure --target-list=riscv64-softmmu,riscv64-linux-user
make -j$(nproc)vim ~/.bashrc
# 配置环境变量（具体路径根据实际情况写）：export PATH=$PATH:/path/to/qemu-7.0.0/buildsource ~/.bashrc# 检查qemu-riscv64环境是否安装配置成功
qemu-system-riscv64 --version
qemu-riscv64 --version
