Linux kernel 为Linux内核构建rootfs时出错

我试图通过引用来构建我的根文件系统

我所做的改变是（arm linux gnueabi-代替arm linux-）

此步骤失败（部分错误日志）。请告知

在vinay hunachyal的帮助下，答案如下

• 使用最新稳定的busybox代码
• 对所有步骤使用相同的工具链（arm none linux gnueabi gcc）（与博客上实际给出的不同）

---

您已经试过了吗？它将关心您的工具链和rootfs。此外，你可以在许多包裹中选择。不，我没有。它用于构建根文件系统吗？是的。您甚至可以在文件系统类型、压缩等之间进行选择。只需下载它，执行make menuconfig并查看菜单选项。您使用的工具链是arm none linux gnueabi gcc还是arm linux gnueabi-？请使用相同的工具链，即arm none linux gnueabi gcc进行所有步骤，如果工作正常，请告诉我。我猜是由于工具链的改变，你得到了错误
