交叉编译Python-3.6.8

准备

平台

安装　python3.6
安装　交叉编译器（按实际工程安装对应版本，这里是gcc 版本 8.2.1 20180802 (GNU Toolchain for the A-profile Architecture 8.2-2018-08 (arm-rel-8.23))）

源码

Python-3.6.8.tgz
zlib-1.2.11.tar.xz
openssl-1.1.1d.tar.gz

sudo mv /usr/bin/lsb_release_ /usr/bin/lsb_release

根据需要修改交叉编译器、SSL_LIB和ZLIB_LIB的路径。

编译

chmod +x build.sh
sudo ./build.sh

输出

ls python_arm/
bin  include  lib  share
