正文

1、下载解压python源码

到https://www.python.org/downloads/下载最新的python2系列的软件，这里我用的是Python-2.7.13

1 #解压
2 tar -xf Python-2.7.13.tar.xz
3 
4 #创建python2_7_13_for_x86_64
5 mkdir python2_7_13_for_x86_64
6 
7 #创建python2_7_13_for_arm
8 mkdir python2_7_13_for_arm

2、编译x86_64版本的python软件

我把编译过程写成了脚本， 进入python2_7_13_for_x86_64/目录，然后执行如下脚本：

  • 配置 mk1_conf.sh 

1 #!/bin/bash
2 
3 ../Python-2.7.13/configure --prefix=`pwd`

  • 编译mk2_make.sh

1 #!/bin/bash
2 
3 make -j4

  • 安装 mk3_install.sh

1 #!/bin/bash
2 
3 make install

3、交叉编译

交叉编译的第一步是为python源码打上交叉编译用的patch：Python-2.7.13-compile.patch.tar.gz

1 cd Python-2.7.13/
2 patch -p1 < ../python2_7_13_for_arm/Python-2.7.13-xcompile.patch

我也把编译过程放到脚本，也分为三个：

  • 配置 mk1_conf.sh

1 #!/bin/bash
2 export PATH=/home/pengdonglin/src/qemu/aarch32/arm-2014.05/bin:$PATH
3 ../Python-2.7.13/configure --prefix=`pwd` \
4     --host=arm-none-linux-gnueabi \
5     --build=x86_64-linux-gnu \
6     --enable-ipv6 \
7     --enable-shared \
8     ac_cv_file__dev_ptmx="yes" \
9     ac_cv_file__dev_ptc="no"

  • 编译 mk2_make.sh

 1 #!/bin/bash
 2 export PATH=/home/pengdonglin/src/qemu/aarch32/arm-2014.05/bin:$PATH
 3 make HOSTPYTHON=../python2_7_13_for_x86_64/python \
 4     HOSTPGEN=../python2_7_13_for_x86_64/Parser/pgen \
 5     BLDSHARED="arm-none-linux-gnueabi-gcc -shared" \
 6     CROSS_COMPILE=arm-none-linux-gnueabi- \
 7     CROSS_COMPILE_TARGET=yes \
 8     HOSTARCH=arm-none-linux-gnueabi \
 9     BUILDARCH=x86_64-linux-gnu \
10     -j4

  • 安装 mk3_install.sh

1 #!/bin/bash
2 export PATH=/home/pengdonglin/src/qemu/aarch32/arm-2014.05/bin:$PATH
3 make install HOSTPYTHON=../python2_7_13_for_x86_64/python \
4     BLDSHARED="arm-none-linux-gnueabi-gcc -shared" \
5     CROSS_COMPILE=arm-none-linux-gnueabi- \
6     CROSS_COMPILE_TARGET=yes \
7     prefix=`pwd`

 

4、重新制作ramdisk镜像

参考博文：用Qemu搭建aarch32学习环境

修改mk_ramdisk.sh如下：

 1 #!/bin/bash
 2 sudo rm -rf rootfs
 3 sudo rm -rf tmpfs
 4 sudo rm -rf ramdisk*
 5 sudo mkdir rootfs
 6 sudo cp ../busybox-1.24.2/_install/*  rootfs/ -raf
 7 sudo mkdir -p rootfs/proc/
 8 sudo mkdir -p rootfs/sys/
 9 sudo mkdir -p rootfs/tmp/
10 sudo mkdir -p rootfs/root/
11 sudo mkdir -p rootfs/var/
12 sudo mkdir -p rootfs/mnt/
13 sudo cp etc rootfs/ -arf
14 sudo cp -arf ../arm-2014.05/arm-none-linux-gnueabi/libc/lib rootfs/
15 sudo rm -rf rootfs/lib/*.a
16 sudo /home/pengdonglin/src/qemu/aarch32/arm-2014.05/bin/arm-none-linux-gnueabi-strip rootfs/lib/*
17 # 拷贝python相关的文件到根文件系统中
18 sudo mkdir -p rootfs/usr
19 pushd rootfs/usr
20 sudo cp  -raf /home/pengdonglin/src/qemu/python_cross_compile/python2_7_13_for_arm/lib .
21 sudo cp  -raf /home/pengdonglin/src/qemu/python_cross_compile/python2_7_13_for_arm/include .
22 sudo cp  -raf /home/pengdonglin/src/qemu/python_cross_compile/python2_7_13_for_arm/bin .
23 sudo cp  -raf /home/pengdonglin/src/qemu/python_cross_compile/python2_7_13_for_arm/share .
24 sudo /home/pengdonglin/src/qemu/aarch32/arm-2014.05/bin/arm-none-linux-gnueabi-strip lib/python*
25 popd
26 sudo mkdir -p rootfs/dev/
27 sudo mknod rootfs/dev/tty1 c 4 1
28 sudo mknod rootfs/dev/tty2 c 4 2
29 sudo mknod rootfs/dev/tty3 c 4 3
30 sudo mknod rootfs/dev/tty4 c 4 4
31 sudo mknod rootfs/dev/console c 5 1
32 sudo mknod rootfs/dev/null c 1 3
33 sudo mkdir -p rootfs/lib/modules/4\.10\.0\+
34 sudo mkdir -p rootfs/tools
35 sudo cp ./other_tools/* rootfs/tools
36 # 将ramdisk的大小扩展为100MB
37 sudo dd if=/dev/zero of=ramdisk bs=1M count=100
38 sudo mkfs.ext4 -F ramdisk
39 sudo mkdir -p tmpfs
40 sudo mount -t ext4 ramdisk ./tmpfs/  -o loop
41 sudo cp -raf rootfs/*  tmpfs/
42 sudo umount tmpfs
43 sudo gzip --best -c ramdisk > ramdisk.gz
44 sudo mkimage -n "ramdisk" -A arm -O linux -T ramdisk -C gzip -d ramdisk.gz ramdisk.img

这里需要注意：

1、将刚才交叉编译python所得的文件拷贝到rootfs/usr下面： bin、lib、include和share

2、由于Python的lib目录占用了很大空间，有70MB左右，所以这里我们把ramdisk的大小设置为100MB

3、此外，qemu-system-arm运行的，可以给-m设置较大的物理内存，这里我设置的是1GB

5、修改kernel配置

修改ramdisk的大小设置， 这里我设置的是100MB：

1 Device Drivers  ---> 
2 
3         [*] Block devices  --->
4 
5                 (102400) Default RAM disk size (kbytes)

6、测试

制作好ramdisk以及编译出新的kernel后，运行系统：

 1 sudo qemu-system-arm \
 2     -M vexpress-a9 \
 3     -m 1024M \
 4     -smp 2 \
 5     -kernel ./linux-4.10/out_aarch32/arch/arm/boot/zImage \
 6     -nographic \
 7     -append "root=/dev/ram0 rw rootfstype=ext4 console=ttyAMA0 init=/linuxrc ignore_loglevel" \
 8     -initrd ./rootfs/ramdisk.img \
 9     -net nic,vlan=0 -net tap,vlan=0,ifname=tap0 \
10     -dtb ./linux-4.10/out_aarch32/arch/arm/boot/dts/vexpress-v2p-ca9.dtb
下面是启动log：
  1 $./run.sh 
  2 sudo tunctl -u root -t tap0
  3 TUNSETIFF: Device or resource busy
  4 sudo ifconfig tap0 0.0.0.0 promisc up
  5 sudo brctl addif br0 tap0
  6 brctl show
  7 bridge name    bridge id        STP enabled    interfaces
  8 br0        8000.480fcf3ace87    no        eth0
  9                             tap0
 10 docker0        8000.02423772cc85    no
