Cross-compile Python-2.7.13 to ARM (aarch64) platform

The method is basically the same as cross-compiling Python-2.7.13 to ARM (aarch32) platform. The only difference is that the toolchain is replaced with the toolchain for compiling aarch64. You can refer to using qemu to build an aarch64 learning environment.

Create a directory:

mkdir python2_7_13_for_aarch64

Here are the scripts for configuration, compilation and installation:

1. Configuration: 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. Compile: 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. Installation: 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`

Also, don't forget to modify the ramdisk creation script and the kernel configuration.

Run Qemu:

 1 sudo qemu-system-aarch64

 2     -M  virt

 3     -cpu cortex-a53

 4 - junior high school 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

Start 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

 10 docker0        8000.024280392ab1    no
