linux docker arm环境搭建,arm 开发环境搭建-基于QEMU和Docker

又花了半天的时间终于搞完了,实现了半自动化搭建环境.废话少说,开始了!!

主要思路:在Docker容器中交叉编译linux-3.16,busybox-1.20.2.在主机中制作根目录并搭建QEMU模拟硬件运行环境.

Docker镜像制作脚本Dockerfile如下:FROM ubuntu:16.04

WORKDIR /root/

RUN apt-get update && apt-get install bc xz-utils bzip2 wget make gcc gcc-4.9-arm-linux-gnueabi vim -y

ADD busybox-1.20.2.tar.bz2 ./

ADD linux-3.16.tar.xz ./

COPY compile.sh mkvm.sh ./

由脚本可知需要在buid content(Dockerfile文件所在的目录)中准备四个文件(下载连接 busybox,linux):## 源文件

busybox-1.20.2.tar.bz2

linux-3.16.tar.xz

## shell 脚本

compile.sh // 编译源文件

mkvm.sh // 从编译完成的文件中收集QEMU运行所需要的文件,并打包成vm.tar.bz2#!/bin/bash

# link arm-gcc

[ ! -f /usr/bin/arm-linux-gnueabi-gcc ] && ln -s /usr/bin/arm-linux-gnueabi-gcc-4.9 /usr/bin/arm-linux-gnueabi-gcc

# compile busybox

cd /root/busybox-1.20.2/

[ ! -f include/.libbb.h ] && cp include/libbb.h include/.libbb.h

sed '43i #include' include/.libbb.h > include/libbb.h # why? 请参考我的文章 交叉编译busybox

make defconfig

make CROSS_COMPILE=arm-linux-gnueabi-

make install CROSS_COMPILE=arm-linux-gnueabi-

# compile kernel

cd /root/linux-3.16/

# collect files to rootfs/

cd /root/

mkdir -p vm/rootfs/{proc,etc/init.d,sys,tmp,root,var,mnt,lib,dev}

cp busybox-1.20.2/_install/* vm/rootfs/ -r

cp busybox-1.20.2/examples/bootfloppy/etc/* vm/rootfs/etc/ -r

cp /usr/arm-linux-gnueabi/lib/* vm/rootfs/lib/ -Pr

dd if=/dev/zero of=a9rootfs.ext3 bs=1M count=32

mkfs.ext3 a9rootfs.ext3

mv a9rootfs.ext3 vm/a9rootfs.ext3

cp linux-3.16/arch/arm/boot/dts/vexpress-v2p-ca9.dtb vm/

cp linux-3.16/arch/arm/boot/zImage vm/

# generate boot.sh mkrootfs.sh

cat > vm/boot.sh << EOF

cat > vm/mkrootfs.sh << EOF

sudo mknod ./rootfs/dev/tty1 c 4 1

sudo mknod ./rootfs/dev/tty2 c 4 2

mkdir tmpfs

sudo mount -t ext3 a9rootfs.ext3 tmpfs/ -o loop

sudo cp rootfs/* tmpfs/ -r

# tar

tar cjf vm.tar.bz2 vm/

rm -fr vm

此时build content中有五个文件:light@light-Inspiron-3559 ~/Docker/arm $ ls

busybox-1.20.2.tar.bz2 compile.sh Dockerfile linux-3.16.tar.xz mkvm.sh

build一下,"镜子"就做好了:light@light-Inspiron-3559 ~/Docker/arm $ docker build -t arm-compil ./

light@light-Inspiron-3559 ~/Docker/arm $ docker images | grep arm

arm-compile latest 1bb5ddf21eca About an hour ago 929MB

足足有1G....^.^```

构建容器:light@light-Inspiron-3559 ~/Docker/arm $ docker run --name arm -ti arm-compil /bin/bash

编译源文件:root@5845a78f3cc9:~# bash compile.sh

从编译完成的文件中收集QEMU运行所需要的文件,并打包成vm.tar.bz2:root@5845a78f3cc9:~# bash mkvm.sh

解包,切换文件,构建根文件:light@light-Inspiron-3559 ~/Docker/arm $ tar xjf vm.tar.bz2 ; cd vm

light@light-Inspiron-3559 ~/Docker/arm/vm $ bash mkrootfs.sh
