iMX6系列-iMX6Q 开发板 Python 移植
本文基于飞凌OKMX6Q/DL开发板为基础讲解，主要使用平台是imx6系列，linux3.0.35操作系统，其他平台也可以参考，不同平台之间会存在差异，需自行修改适应自己的使用iMX6 Python移植注：所需工具包在Python移植/工具包 已经生成的可移植Python在Python移植/output过程一：Python编译过程准备工作以下文件在下面的编译中需要用到Python-2.7.13.tgzsqlite-autoconf-3200100.tar.gzPython-2.7.13-xcompile.patch.tar.gzntp-4.2.8p10.tarsetuptools-0.6c11-py2.7.eggopenssl-OpenSSL_1_0_1b.zipzlib-1.2.3.tar.g准备环境cd /rootmkdir mx6q-python2.7/ && cd mx6q-python2.7mkdir –p {python2_7_13_for_x86_64,python2_7_13_for_arm,INSTALL,sqlite3,misc,output/sources}复制上文中准备的软件包到mx6q-python2.7,把zlib-1.2.3.tar.gz和openssl-OpenSSL_1_0_1b.zip移动到misc目录下。或者直接复制提供的软件包中mx6q-python2.7文件到/root目录下。
确定交叉编译工具链确定当前交叉编译器链,如果交叉编译链不一致， 替换下文中的编译器。当前的交叉编译链为arm-none-linux-gnueabi-.可以通过下面命令确定当前编译链。find / -name arm-*-gcc如果交叉编译链不一致，替换下文中的编译器
编译安装编译安装sqlite3编译安装sqlite3, python需要sqlite3支持。cd /root/mx6q-python2.7/
tar xvf sqlite-autoconf-3200100.tar.gz
cd sqlite-autoconf-3200100
./configure --host=arm-none-linux-gnueabi --prefix=$PWD/../sqlite3

cd openssl-OpenSSL_1_0_1b
mkdir arm_install
./Configure --prefix=`pwd`/arm_install/ os/compiler:arm-none-linux-gnueabi-gcc需要修改Makefile中的CC变量为CC= $(CROSS_COMPILE)gccmake
make install打包编译好的安装包,移植到开发板需要用到cd arm_install

LDFLAGS="-L$PWD/../sqlite3/lib -L$PWD/lib" \
CPPFLAGS="-I$PWD/../sqlite3/include -I$PWD/include -I$PWD/include/openssl"在下一步make执行之前，需要先安装zlib和openssl，并将其各自的include和lib拷贝到python2_7_13_for_arm文件夹下.或者可直接运行py2-cp-libAndssl-arm-toHere.sh脚本会自动把misc下的zlib和openssl库的头文件和库拷贝到当前目录下。编译cd /root/mx6q-python2.7/python2_7_13_for_arm/运行py2make-for-arm.sh或者运行下面的命令。make HOSTPYTHON=../python2_7_13_for_x86_64/python \HOSTPGEN=../python2_7_13_for_x86_64/Parser/pgen \BLDSHARED="arm-none-linux-gnueabi-gcc -shared" \CROSS_COMPILE=arm-none-linux-gnueabi- \CROSS_COMPILE_TARGET=yes \HOSTARCH=arm-none-linux-gnueabi \BUILDARCH=x86_64-linux-gnu \SSL=`pwd`安装运行py2install.sh或者运行下面的命令。make install HOSTPYTHON=../python2_7_13_for_x86_64/python \

└── setuptools-0.6c11-py2.7.egg到此，python编译完整， 移植到开发板的步骤请参考"python2.7直接使用手册".过程二：Python在开发板配置将以上生成的output文件夹拷贝到iMX6Q开发板1. 解压缩包岛开发版tarxvfpython2.7-arm.tar.bz2-C/tarxvfopenssl-OpenSSL_1_0_1b.tar.bz2-C/cpsetuptools-0.6c11-py2.7.egg/ cp ntp-4.2.8p10-arm-no-share.tar.gz/2. 修改配置修改文件/lib/pkgconfig/python2.pc如下.
prefix=/
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include修改文件vi /bin/python2.7-config的第一行如下.#!/bin/python2.7在/etc/profile中添加一下配置， 修改成功后source /etc/profileexport PYTHONHOME=/
export PYTHONPATH=$PYTHONHOME:$PYTHONHOME/lib/python2.7:$PYTHONHOME/lib:$PYTHONHOME/lib/python2.7/site-packages
export PATH=$PATH:$PYTHONHOME:$PYTHONPATH3.进入到easy_install文件夹， 安装easy_install.输入 /bin/bash setuptools-0.6c11-py2.7.egg 安装easy_install.修改文件vi /etc/profile,添加alias easy_install='easy_install -i http://pypi.douban.com/simple'.保存退出便于之后安装管理, source /etc/profile使生效配置4. 取消SSL全局验证并验证easy_install,修改文件vi /bin/easy_install增加如下配置. import ssl
ssl._create_default_https_context = ssl._create_unverified_context5. 配置好网络参考其他配置应用笔记配置网络的方法。6. 安装ntp网络对时， 进入ntp文件夹.tar xvf ntp-4.2.8p10-arm-no-share.tar.gz -C /
ntpdate time.buptnet.edu.cn注：此处可能因为对时网址问题会出现错误，针对报错信息直接搜索即可解决。7. 安装pipeasy_install pip 安装成功后, pip -V 查看当前安装版本.8. pip安装模块测试 pip install requestspip list 查看已安装的模块.9. 导入模块测试,输入python2.7进入python2.7 shell.输入 import requests，无错误输出。输入exit() 退出python shell.
支持一下，配置咋这么复杂呢？ 谢谢分享，问一下，IMX6能装python3和opencv库吗？
