例如，我可以为目标构建mips64el-linux-gnu：

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

但不适用于目标mipsel-linux-gnu：

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

如何为这个目标构建？或者至少找出可用目标的完整列表？

找出可用目标的完整列表

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

如何为这个目标构建？

你可以：

  1. 用你未来的包创建一个空目录；

  2. 将路径保存到环境变量中$GUIX_PACKAGE_PATH；

  3. 将提到的bootstrap.scm文件放在这里：$GUIX_PACKAGE_PATH/gnu/packages/bootstrap.scm;

  4. 对其进行必要的更改：

    diff --git a/gnu/packages/bootstrap.scm b/gnu/packages/bootstrap.scm
index 5a8028a465..102e7378ae 100644
--- a/gnu/packages/bootstrap.scm
+++ b/gnu/packages/bootstrap.scm
@@ -317,6 +317,7 @@ or false to signal an error."

         ((string=? system "s390x-linux") "/lib/ld64.so.1")
         ((string=? system "riscv64-linux") "/lib/ld-linux-riscv64-lp64d.so.1")
+        ((string=? system "mipsel-linux") "/lib/ld.so.1")

         ;; XXX: This one is used bare-bones, without a libc, so add a case
         ;; here just so we can keep going.

  5. 并构建一个包（同时会构建一整套compiler/binutils/etc.-gcc-toolchain-）：

    $ guix build --target=mipsel-linux-gnu hello
...
