交叉编译Python-2.7.13到ARM（aarch64）平台

方法跟交叉编译Python-2.7.13到ARM（aarch32）平台基本一样， 不同的地方只是把工具链换成编译aarch64的工具链，这里可以参考用qemu搭建aarch64学习环境.

创建目录：

mkdir python2_7_13_for_aarch64

下面是配置、编译和安装的脚本：

1、配置: mk1_conf.sh

#!/bin/bash

export PATH=/home/pengdonglin/src/qemu/aarch64/gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/bin:$PATH

../Python-2.7.13/configure --prefix=`pwd` \
--host=aarch64-linux-gnu \
--build=x86_64-linux-gnu \
--enable-ipv6 \
--enable-shared \
ac_cv_file__dev_ptmx="yes" \
ac_cv_file__dev_ptc="no"

2、编译： mk2_make.sh

#!/bin/bash

export PATH=/home/pengdonglin/src/qemu/aarch64/gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/bin:$PATH

make HOSTPYTHON=../python2_7_13_for_x86_64/python \
HOSTPGEN=../python2_7_13_for_x86_64/Parser/pgen \
BLDSHARED="aarch64-linux-gnu-gcc -shared" \
CROSS_COMPILE=aarch64-linux-gnu- \
CROSS_COMPILE_TARGET=yes \
HOSTARCH=aarch64-linux-gnu \
BUILDARCH=x86_64-linux-gnu \
-j4

3、安装： mk3_install.sh

#!/bin/bash

export PATH=/home/pengdonglin/src/qemu/aarch64/gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/bin:$PATH

make install HOSTPYTHON=../python2_7_13_for_x86_64/python \
BLDSHARED="aarch64-linux-gnu-gcc -shared" \
CROSS_COMPILE=arm-none-linux-gnueabi- \
CROSS_COMPILE_TARGET=yes \
prefix=`pwd`

此外别忘了修改制作ramdisk的脚本以及修改内核配置。

运行Qemu：

sudo qemu-system-aarch64 \
-M  virt \
-cpu cortex-a53 \
-smp 2 \
-m 4096M \
-kernel ./linux-4.10/out_aarch64/arch/arm64/boot/Image \
-nographic \
-append "root=/dev/ram0 rw rootfstype=ext4 console=ttyAMA0 init=/linuxrc ignore_loglevel" \
-initrd ./rootfs/ramdisk.img \
-net nic,vlan=0 -net tap,vlan=0,ifname=tap0 \
-fsdev local,security_model=passthrough,id=fsdev0,path=/nfsroot \
-device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare

启动log：

$./run_all.sh
sudo tunctl -u root -t tap0

sudo ifconfig tap0 0.0.0.0 promisc up
