教你小技巧——Python 移植教程

教你小技巧——Python 移植教程

        这篇文章中会详细讲到关于Python的移植教程，过程复杂，操作稍微麻烦，但是值得尝试。

一、使用的源文件需要自行从网上下载。

二、准备文件：

Python-2.7.13.tgz

sqlite-autoconf-3200100.tar.gz

Python-2.7.13-xcompile.patch.tar.gz

————————————————

步骤1、准备环境

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

————————————————

步骤2、安装sqlite

cd sqlite-autoconf-3200100

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

    --prefix=$PWD/../sqlite3

make

make install

————————————————

步骤3、安装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

————————————————

步骤4、打补丁

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

————————————————

步骤5、配置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"

————————————————

步骤6、编译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

————————————————

步骤7、安装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

————————————————

步骤8、移植到开发板之后的配置

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/

为Python安装easy_install工具

————————————————

步骤1、下载setuptools-0.6c11-py2.7.egg

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

————————————————

步骤2、安装easy_install

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

————————————————————————————————————————————

————————————————————————————————————————————

修改openssl.so库的版本

————————————————

步骤1、下载openssl-OpenSSL_1_0_1b.zip，并解压缩

tar xvf openssl-OpenSSL_1_0_1b.zip

————————————————

步骤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/

————————————————

步骤3、在开发板上进行操作

mv /media/mmcblk1p1/arm_install.tar /

tar xvf arm_install.tar

cp -r /arm_install/lib/* /usr/lib

cp /arm_install/bin/* /usr/bin/

————————————————

步骤4、取消SSL全局验证并验证easy_install

vi /INSTALL/bin/easy_install

增加

import ssl

ssl._create_default_https_context = ssl._create_unverified_context

easy_install web.py

————————————————

步骤5、安装pip工具

easy_install pip

//此时使用pip工具会报SSL 认证错误，需要安装ntp网络对时

————————————————————————————————————————————

########################################################################################

————————————————————————————————————————————

移植ntp网络对时 (335x已有不用移植)

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

--------------------------------------

./ntpdate time.buptnet.edu.cn

    步骤虽然比较麻烦，但是大家可以尝试一番，Python并不是一个简单的程序，所以大家可以尝试来学习一下。
