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
