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
1 #!/bin/bash
2
3 export PATH=/home/pengdonglin/src/qemu/aarch64/gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/bin:$PATH
4
5 ../Python-2.7.13/configure --prefix=`pwd` \
6 --host=aarch64-linux-gnu \
7 --build=x86_64-linux-gnu \
8 --enable-ipv6 \
9 --enable-shared \
10 ac_cv_file__dev_ptmx="yes" \
11 ac_cv_file__dev_ptc="no"
2、编译： mk2_make.sh
1 #!/bin/bash
2
3 export PATH=/home/pengdonglin/src/qemu/aarch64/gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/bin:$PATH
4
5 make HOSTPYTHON=../python2_7_13_for_x86_64/python \
6 HOSTPGEN=../python2_7_13_for_x86_64/Parser/pgen \
7 BLDSHARED="aarch64-linux-gnu-gcc -shared" \
8 CROSS_COMPILE=aarch64-linux-gnu- \
9 CROSS_COMPILE_TARGET=yes \
10 HOSTARCH=aarch64-linux-gnu \
11 BUILDARCH=x86_64-linux-gnu \
12 -j4
3、安装： mk3_install.sh
1 #!/bin/bash
2
3 export PATH=/home/pengdonglin/src/qemu/aarch64/gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/bin:$PATH
4
5 make install HOSTPYTHON=../python2_7_13_for_x86_64/python \
6 BLDSHARED="aarch64-linux-gnu-gcc -shared" \
7 CROSS_COMPILE=arm-none-linux-gnueabi- \
8 CROSS_COMPILE_TARGET=yes \
9 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：
1 sudo qemu-system-aarch64 \
2 -M virt \
3 -cpu cortex-a53 \
4 -smp 2 \
5 -m 4096M \
6 -kernel ./linux-4.10/out_aarch64/arch/arm64/boot/Image \
7 -nographic \
8 -append "root=/dev/ram0 rw rootfstype=ext4 console=ttyAMA0 init=/linuxrc ignore_loglevel" \
9 -initrd ./rootfs/ramdisk.img \
10 -net nic,vlan=0 -net tap,vlan=0,ifname=tap0 \
11 -fsdev local,security_model=passthrough,id=fsdev0,path=/nfsroot \
12 -device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare
启动log：
1 $./run_all.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 8000.36de5b2e5a93 no eth0
9 tap0
