很多朋友只有x86的系统,因为我们上学时代和工作机大部分都x86系统。loongson推出LoongArch指令集后,也想尝尝鲜或者作为一个开发者又不想买新的机器,此时就可以用到我下边为大家介绍的方法。
此处也给大家提供一个debian社区发布的官方的文档:
debian社区发布:LoongArch/sbuildQEMU - Debian Wiki
也可以参考我为大家已经整理好的资料 GitHub - loongson-zn/qemu-debian
如果你翻墙困难,我将整理的readme粘贴到此处:
宿主机环境
架 构:x86_64
系统环境:debian bookworm
具体操作步骤:
-
安装qemu-user
root@debian:~# apt install binfmt-support
root@debian:~# apt build-dep qemu-user-static
root@debian:~# git clone https://github.com/qemu/qemu.git
root@debian:~# cd qemu
root@debian:~/qemu# ./configure --static --disable-system --target-list=loongarch64-linux-user
root@debian:~/qemu# make
root@debian:~/qemu# cp build/loongarch64-linux-user/qemu-loongarch64 /usr/bin/qemu-loongarch64-static
root@debian:~/qemu# cat >/tmp/qemu-loongarch64 <<EOF

制作LA最小镜像
root@debian:~# apt install debootstrap sbuild debian-ports-archive-keyring
root@debian:~# debootstrap --foreign --arch=loong64 --variant=buildd --include=debian-ports-archive-keyring --verbose --components=main --keyring=/etc/apt/trusted.gpg.d/debian-ports-archive-2023.gpg --resolve-deps --extra-suites=unreleased unstable /srv/chroots/sid-loong64-sbuild/ http://ftp.ports.debian.org/debian-ports
root@debian:~# cd /srv/chroots/sid-loong64-sbuild/
root@debian:/srv/chroots/sid-loong64-sbuild# cp /usr/bin/qemu-loongarch64-static usr/bin/
root@debian:/srv/chroots/sid-loong64-sbuild# chroot .
I have no name!@loongson01:/# /debootstrap/debootstrap --second-stage -
准备gcc编译器(我提供的gcc及qemu是支持lasx及lsx向量的,如果不需要,用debian仓库安装即可)
git clone https://github.com/loongson-zn/qemu-debian.git
cd qemu-debian/gcc_13.2.0-7.1_nodbg
apt install ./*
apt install gcc gfortran
mount -t proc proc proc
mount -t sysfs sys sys
mount -t devtmpfs dev dev
mount -t devpts devpts dev/pts
mount -t tmpfs shmfs dev/shm
