Error solving when ARN Linux compiles the system

Today intends to compile support Orange PI Development Board Raspbain Jessie System from GitHub to take the source, download, compile, has been relatively smooth

The result is half-compiled with an error:

206:/bin/sleepfile: Exec format error

Based on the error message, the statement was found as follows:

     while kill -0 $12>/dev/nulldo          i=$ (((i+ 1)%4  )      "\r$2 ${spin: $i: 1}"       Sleep . 1     Done

A simple sleep, how can be malformed? It's okay to do it alone? Continue to look up, found in the Create_image script called the Second-stage, the call statement is as follows:

# ********************************************************************************# If running on ARM (ORANGEPI) with the line without"qemu-arm-static"!!! ****# ********************************************************************************#if! Chroot $odir/bin/bash/second-stage; Thenif!chroot$odir/usr/bin/qemu-arm-static-cpu Cortex-a9/bin/bash/second-stage; Then    MV$odir/Install. log. >/dev/NULL 2>&1    Echo "================================================"    Echo "ERROR on Second-stage, instalation not finished."    Echo "================================================"Exit1fi

The original is called after executing the chroot, which means that the actual call is

~/orangepi/orangepih3/output/linux-jessie/bin/Sleep

But it is specified here to be called with the qemu-arm-static command, how is it wrong? What is the use of this command? The following tests were done:

sudo chroot ~/orangepi/orangepih3/output/linux-Jessie/usr/bin/qemu-arm-static-cpu cortex-a9/bin/ Bash

Smooth call! But under the arm version of Bash, it's still not possible to call/bin/sleep, which is the same hint:

file: Exec format error

The original qemu-arm-static is only valid for the current program, and does not change the System program execution environment, so the arm version of the/bin/sleep as a x86 program has been processed, which is called/bin/ Sleep also needs to use the qemu-arm-static command to invoke, do you need to change the script? That's a lot of change, is there a convenient way?

So Google took the next, in the article:

Emulating ARM on Debian/ubuntu

, a key step is missing:

#This can only is run as root (sudo don't work)sudosuecho'  : arm:m::\x7felf\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x28\x00:\xff\xff\xff\xff\xff\ Xff\xff\x00\xff\xff\xff\xff\xff\xff\xff\xff\xfe\xff\xff\xff:/usr/bin/qemu-arm-static:' >/proc/ sys/fs/binfmt_misc/registerexit

This statement means to register qemu-arm-static as the default interpreter for ARM executables! After performing this step, you do not need to specify qemu-arm-static as the interpreter, directly call the ARM program to execute

Continue with the compilation, success!
