不幸的是，debhelper 具有递归依赖性。
当我尝试安装时apt-get source --compile debhelper，它说：

然后当我这样做时apt-get source --compile po4a，它说：

我可以编译除 debhelper 之外的所有其他包，因为它需要 po4a，而 po4a 又需要 debhelper，依此类推。
编辑：顺便说一句，我有不须藤使用权。
答案1
debhelper可以在没有 NLS 的情况下构建，这不需要po4a;看https://bugs.debian.org/709557了解详情。一旦你有了 的源代码debhelper，你就可以运行
USE_NLS=no dpkg-buildpackage -d -b -uc
获得可安装的.deb，然后您可以使用它来构建po4a，然后debhelper使用 NLS 重新构建。
请注意，这debhelper是一个Architecture: all包，因此不需要为新架构重新构建它，因此不会在引导努力。
