python arm开发_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

10 docker0        8000.024280392ab1    no
