LoongArch Debian bootstrap 项目启动，已可用

杜比

整个自动编译的流程，可以先用如下命令测试了解下：
> ./bootstrap.sh HOST_ARCH=mips64el GCC_VER=12
实测，使用sid的源，可以完成整个bootstrap的构建
loongarch源码逐步添加！

dexter

原来构建Debian的工具这么方便！学习了！

why

这个是需要在x86的电脑上运行？还是在3a5000上运行？

杜比

why x86电脑，debian11 ubuntu都可以，在虚拟机下运行也可以

因为交叉编译的过程先后的次序很重要，所以编译时是单进程的，处理器核多少关系不大
内存越大越好

杜比

因为debian官方或者镜像的代码库目前都不支持loongarch64，所以要单独把源码包下载，解压和再封包
也因为脚本是自动运行的，除非编译出错停止，所以需要配置一个代码库，把做好的包提交到里面，在rebootstrap脚本的第12行进行修改，添加配置的代码库：

: ${MIRROR:="http://http.debian.net/debian"}

why

https://github.com/loongson/binutils-gdb/tree/master

https://github.com/loongson/glibc/tree/release/2.33/master

https://github.com/loongson/gcc/tree/loongarch-12

我下载上面的源码然后把debootstrap-la下对应的修改并入之后打成deb包放入在rebootstrap脚本的第12行进行修改，添加配置的代码库。是这样的吧

杜比

why 建议先按2楼的说明，先跑一遍mips64el的，看下过程。项目里使用的源码都是debian sid代码包加入loongarch补丁的方式

杜比

debian sid源代码库发生变化，linux从5.16升级到了5.17，gcc的cross补丁版本也升级了，所以新开了个分支linux-5.17，后续构建主要在这个分支。
升级到5.17，基于 github.com/loongson/linux 制作的补丁全部可用

大道无形若水

杜比厉害，继续加油

杜比

5月6日发布的gcc12.1已经进入debian sid ，已包含提交的loongarch基础代码

杜比

代码库建了一个20220606分支，三大件bootstrap交叉编译已全部完成

大道无形若水

杜比强

时空质能

有没有考虑用龙芯旧世界的工具链从零开始交叉编译debian10，还可以使用向量指令

淡炒番茄

时空质能不仅是工具链，基础的库例如glibc等，也是旧世界。

如果你仅仅想用更新的软件，可以自行挑选软件包编译，这样反而方便。

杜比

时空质能 loongnix 20 就是基于debian10的，目前有个extralibs库的项目，一方面针对loongnix20查漏补缺，另一方面在版本不冲突的前提下，爱好者可以提交一些新版本的deb包。
