Tutorial on porting Python to arm

The source files you use need to be downloaded from the Internet.

Prepare the file:

Python-2.7.13.tgz

Sqlite-autoconf-3200100.tar.gz

Python-2.7.13-xcompile.patch.tar.gz

-

Step 1. Prepare the environment

Tar xvf Python-2.7.13.tgz

Tar xvf sqlite-autoconf-3200100.tar.gz

Mkdir python2_7_13_for_x86_32

Mkdir python2_7_13_for_arm

Mkdir INSTALL

Mkdir sqlite3

-

Step 2. Install sqlite

Cd sqlite-autoconf-3200100

. / configure-- host=arm-arago-linux-gnueabi\

-- prefix=$PWD/../sqlite3

Make

Make install

-

Step 3. Install python2_7_13_for_x86_32

Cd.. / python2_7_13_for_x86_32/

Sed-I 's/self.extensions.remove (ext) / print (ext.name) / g'.. / Python-2.7.13/setup.py

.. / Python-2.7.13/configure-- prefix= `pwd`

Make

Make install

-

Step 4. Patch

Cd..

Tar xvf Python-2.7.13-xcompile.patch.tar.gz-C Python-2.7.13

Cd Python-2.7.13/

Patch-p1 < Python-2.7.13-xcompile.patch

-

Step 5. Configure python2_7_13_for_arm

Cd.. / python2_7_13_for_arm/

.. / Python-2.7.13/configure-- prefix= `pwd`\

-- host=arm-arago-linux-gnueabi\

-- build=i686-linux-gnu\

-- enable-ipv6\

-- enable-static\

Ac_cv_file__dev_ptmx= "yes"\

Ac_cv_file__dev_ptc= "no"\

LDFLAGS= "- L$PWD/../sqlite3/lib"\

CPPFLAGS= "- I$PWD/../sqlite3/include"

-

Step 6. Compile python2_7_13_for_arm

Make HOSTPYTHON=../python2_7_13_for_x86_64/python\

HOSTPGEN=../python2_7_13_for_x86_64/Parser/pgen\

BLDSHARED= "arm-arago-linux-gnueabi-gcc-shared"\

CROSS_COMPILE=arm-arago-linux-gnueabi-\

CROSS_COMPILE_TARGET=yes\

HOSTARCH=arm-arago-linux-gnueabi\

BUILDARCH=i686-linux-gnu

-

Step 7. Install python2_7_13_for_arm

Make install HOSTPYTHON=../python2_7_13_for_x86_64/python\

BLDSHARED= "arm-arago-linux-gnueabi-gcc-shared"\

CROSS_COMPILE=arm-arago-linux-gnueabi-\

CROSS_COMPILE_TARGET=yes\

Prefix=$PWD/../INSTALL

-

Step 8. Configuration after migration to the development board

Export PATH=/INSTALL/bin:$PATH

Python python2.7-config-prefix / INSTALL

Python python2.7-config-includes / INSTALL/include/

Python python2.7-config-libs / INSTALL/lib/

-

#

-

Install easy_install tools for Python

-

Step 1. Download setuptools-0.6c11-py2.7.egg

Wget https://pypi.python.org/packages/25/5d/cc55d39ac39383dd6e04ae80501b9af3cc455be64740ad68a4e12ec81b00/setuptools-0.6c11-py2.7.egg#md5=fe1f997bc722265116870bc7919059ea

-

Step 2. Install easy_install

/ bin/sh setuptools-0.6c11-py2.7.egg

-

#

-

Modify the version of the openssl.so library

-

Step 1. Download openssl-OpenSSL_1_0_1b.zip and extract it

Tar xvf openssl-OpenSSL_1_0_1b.zip

-

Step 2,

Mkdir arm_install

CC=arm-arago-linux-gnueabi-gcc

. / Configure linux-elf no-asm-- prefix=$PWD/arm_install-- openssldir=$PWD-- cross-compile-prefix=arm-arago-linux-gnueabi- shared

Make

Make install

Tar cvf arm_install.tar arm_install/

Mv arm_install.tar / media/BOOT/

-

Step 3. Operate on the development board

Mv / media/mmcblk1p1/arm_install.tar /

Tar xvf arm_install.tar

Cp-r / arm_install/lib/* / usr/lib

Cp / arm_install/bin/* / usr/bin/

-

Step 4. Cancel SSL global verification and verify easy_install

Vi / INSTALL/bin/easy_install

Increase

Import ssl

Ssl._create_default_https_context = ssl._create_unverified_context

Easy_install web.py

-

Step 5. Install the pip tool

Easy_install pip

/ / SSL authentication error will be reported when using pip tool at this time, and ntp network alignment needs to be installed.

-

#

-

Porting ntp network timing (335x does not need to be ported)

Wget http://www.eecis.udel.edu/~ntp/ntp_spool/ntp4/ntp-4.2/ntp-4.2.8p10.tar.gz

Tar xvf ntp-4.2.8p10.tar.gz

Cd ntp-4.2.8p10/

Mkdir arm_install

CC=arm-arago-linux-gnueabi-gcc

. / configure-prefix=$PWD/arm_install-host=arm-arago-linux-gnueabi-enable-static-with-yielding-select=yes

Make

Make install
