求助：chroot运行arm程序的问题

[开天辟地]

x86系统
问题是之前我的chroot到这个arm是成功的
但现在不知为何不行了

[royclark]

我搜到了这个东西： https://wiki.ubuntu.com/ARM/BuildEABIChroot， 也许你是用它来做的，用了 qemu 来模拟。我昨天的观点片面了。
你可以按里面的重新做一次 qemu-debootstrap。
不想重做的话，我觉得可以检查 qemu-user-static 和 binfmt-support 是否安装、正确配置，chroot 里的动态库是否完整，qemu-arm-static 是否复制到了 eabi-chroot/usr/bin 下。

应该是 binfmt 配置有问题。
检查一下宿主机里 binfmt-support 是否安装，update-binfmts --display 是否有类似的输出。

代码： 全选

$ update-binfmts --display
