需求：
|
||
1. 在qemu -machine sifive 上运行起来debian linux for rv64;
|
||
2. 用gcc OR llvm +musl lib编译静态库busybox，能跑在 debian linux for rv64上;
|
||
3. 用gcc OR llvm +musl lib编译静态 helloworld app, 能跑在 debian linux for rv64上。
|
||
|
||
参考：[wiki.debian.org](https://wiki.debian.org/RISC-V#Setting_up_a_riscv64_virtual_machine)
|
||
|
||
#### 0. 环境准备
|
||
|
||
##### 0.1 工具链
|
||
|
||
```
|
||
sudo apt install gcc-riscv64-linux-gnu
|
||
```
|
||
|
||
##### 0.2 qemu
|
||
|
||
```
|
||
git clone https://github.com/qemu/qemu.git
|
||
cd qemu
|
||
./configure --target-list=riscv64-softmmu
|
||
sudo make install
|
||
./configure --target-list=riscv64-linux-user
|
||
sudo make install
|
||
```
|
||
|
||
##### 0.3 创建chroot环境
|
||
|
||
```
|
||
# 注意！！！需要在debian testing版上才可成功创建chroot环境。
|
||
sudo apt install mmdebstrap qemu-user-static binfmt-support debian-ports-archive-keyring
|
||
sudo mmdebstrap --architectures=riscv64 --include="debian-ports-archive-keyring" sid /tmp/riscv64-chroot "deb http://deb.debian.org/debian-ports/ sid main" "deb http://deb.debian.org/debian-ports/ unreleased main"
|
||
sudo chroot /tmp/riscv64-chroot
|
||
passwd
|
||
exit
|
||
```
|
||
|
||
|
||
|
||
#### 1. 编译kernel和BBL
|
||
|
||
```
|
||
wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.19.16.tar.xz
|
||
git clone https://github.com/riscv/riscv-pk
|
||
|
||
cd linux
|
||
make CROSS_COMPILE=riscv64-linux-gnu- ARCH=riscv defconfig
|
||
make CROSS_COMPILE=riscv64-linux-gnu- ARCH=riscv menuconfig
|
||
# Kernel hacking -> Compile-time checks and compiler options -> Compile the kernel with debug info 加入这个选项后可以用gdb调试kernel
|
||
make CROSS_COMPILE=riscv64-linux-gnu- ARCH=riscv -j8
|
||
|
||
cd ../riscv-pk/
|
||
mkdir build
|
||
cd build
|
||
../configure --prefix=/tmp --host=riscv64-linux-gnu --with-payload=../../linux/vmlinux
|
||
# 编译pk的时候，如果提示没有对__stack_chk_guard的引用，需要在Makefile的CFLAGS里加-fno-stack-protector
|
||
# 编译pk的时候，如果提示没有对__vsnprintf_chk的引用，需要在Makefile的CFLAGS里加-U_FORTIFY_SOURCE
|
||
make
|
||
cd ../../
|
||
```
|
||
|
||
#### 2. 创建镜像
|
||
|
||
```
|
||
qemu-img create rootfs.img 10G
|
||
/sbin/mkfs.ext4 rootfs.img
|
||
|
||
mount rootfs.img /mnt -o loop
|
||
cp -r /tmp/riscv64-chroot/* /mnt
|
||
umount /mnt
|
||
```
|
||
|
||
#### 3. 在qemu中运行
|
||
|
||
```
|
||
qemu-system-riscv64 -nographic -machine virt -m 2G -kernel riscv-pk/build/bbl \
|
||
-object rng-random,filename=/dev/urandom,id=rng0 -device virtio-rng-device,rng=rng0 \
|
||
-append "console=ttyS0 rw root=/dev/vda" \
|
||
-device virtio-blk-device,drive=hd0 -drive file=rootfs.img,format=raw,id=hd0 \
|
||
-device virtio-net-device,netdev=usernet -netdev user,id=usernet,hostfwd=tcp::22222-:22
|
||
```
|
||
|
||
#### 4. 设置网络
|
||
|
||
```
|
||
# 编辑/etc/network/interfaces，重启系统以开启dhcp
|
||
auto eth0
|
||
allow-hotplug eth0
|
||
iface eth0 inet dhcp
|
||
```
|
||
|
||
#### 5. 更新源
|
||
|
||
```
|
||
# 编辑/etc/apt/sources.list
|
||
deb http://ftp.ports.debian.org/debian-ports/ sid main
|
||
deb http://ftp.ports.debian.org/debian-ports/ unreleased main
|
||
deb-src http://ftp.ports.debian.org/debian-ports/ sid main
|
||
|
||
# 更新源
|
||
apt update
|
||
apt upgrade
|
||
```
|
||
|
||
#### 6. 静态编译helloworld
|
||
|
||
```
|
||
riscv64-linux-gnu-gcc hello.c -static -o hello
|
||
```
|
||
|
||
#### 7. 静态编译busybox
|
||
|
||
```
|
||
wget https://busybox.net/downloads/busybox-1.30.0.tar.bz2
|
||
tar xjf busybox-1.30.0.tar.bz2
|
||
cd busybox-1.30.0
|
||
make defconfig # 使用默认配置生成.config
|
||
make menuconfig # 调整.config
|
||
# Settings->Build Options选择Build static binary，使用静态编译
|
||
make CROSS_COMPILE=riscv64-linux-gnu- ARCH=riscv -j8 install
|
||
```
|
||
|
||
#### 问题解决
|
||
|
||
1. 问题描述：libwacom9 : Depends: libwacom-common (= 2.2.0-1) but 1.12-1 is to be installed
|
||
|
||
原因分析：依赖冲突？
|
||
|
||
解决方法：`apt install libwacom9 libwacom2-`
