用guix编译缺失目标的交叉编译

Question

例如，我可以为目标mips64el-linux-gnu构建

$ guix build --no-substitutes --target=mips64el-linux-gnu hello
...
successfully built /gnu/store/sdhhi1fhgbldl5qyfwvwlzhf2gq41n0j-hello-2.10.drv
/gnu/store/rbl4yrjyj3vxn27cap1y24z5wkr90p8y-hello-2.10

但不是针对目标mipsel-linux-gnu

$ guix build --no-substitutes --target=mipsel-linux-gnu hello

如何为这一目标构建？或者至少找出可用目标的完整清单？

Answer 1

查找可用目标的完整列表

所有活动目标都列在glibc-dynamic-linker函数中的gnu/packages/bootstrap.scm中。

如何为这个目标构建？

你可以：

1. 与您的未来包一起创建一个空目录；

将该路径保存到环境变量$GUIX_PACKAGE_PATH;中的

$GUIX_PACKAGE_PATH/gnu/packages/bootstrap.scm;：

1. 将提到的bootstrap.scm文件放置在这里：

1. 对其进行了必要的更改：

diff -git a/gnu/packages/bootstrap.scm b/gnu/packages/bootstrap.scm索引5a8028a465.102e7378ae 100644 - a/gnu/packages/bootstrap.scm +++ b/gnu/packages/bootstrap.scm @ -317,6 +317,7 @@或误报错误。“(string=？系统"alpha-linux")“/lib/ld-linux.so.2”(string=？系统"s390x-linux")“/lib/ld64.so.1”((string=？系统“riscv64 64-linux”) "/lib/ld-linux-riscv64-lp64d.so.1") + ((string=？系统“mipsel”) "/lib/ld.so.1")；XXX:这个系统使用裸骨，没有libc，所以添加一个情况;；这里，我们可以继续下去。

1. 并构建一个包(同时，将构建一套完整的编译器/binutils/等等--工具链gcc)：
