mac配置 rcore开发环境

qemu¶

安装依赖

$ brew install libffi gettext glib pkg-config autoconf automake pixman ninja

下载qemu7.0源码

$ wget https://download.qemu.org/qemu-7.0.0.tar.xz

解压

$ tar xvJf qemu-7.0.0.tar.xz

编译

$ mkdir build
$ cd build
../configure --target-list=aarch64-softmmu,riscv64-softmmu --enable-cocoa --disable-sdl

完成后, 把当前目录加入到 PATH路径里

gdb客户端¶

下载客户端

https://static.dev.sifive.com/dev-tools/freedom-tools/v2020.12/riscv64-unknown-elf-toolchain-10.2.0-2020.12.8-x86_64-apple-darwin.tar.gz

解压后在 bin 目录下即可找到 riscv64-unknown-elf-gdb 以及另外一些常用工具 objcopy/objdump/readelf 等

添加到PATH路径内即可

clion的gdb配置¶

由于clion没办法在gdb启动时添加命令行参数设置-ex之类的, 所以我们需要通过环境变量修改启动参数

修改 ~/.gdbinit

set arch riscv:rv64
file /Users/zhangxinyu/Documents/rCore-Tutorial-v3/os/target/riscv64gc-unknown-none-elf/release/os

makefile¶

添加外部工具¶

使其执行前运行Makefile目标debug

其他命令¶
