交叉编译 Python3.10.8¶

此文构建的 Python 含 pip/zlib/ffi

请使用 Ubuntu 22.04，这个版本测试成功编译。

系统自带与需要编译的版本相同的 Python3.10，这省去了需要在本机安装 Python 的过程：

$ python3 -V
Python 3.10.6

首先确保安装了 aarch64-himix200-linux 交叉编译工具链。

其次安装 make：

$ sudo apt-get install build-essential

将zlib加入Python的编译脚本¶

compile-python.sh:

#!/bin/bash
TARGET_HOST="aarch64-himix200-linux" # 这一行有修改 换成HiLinux的编译工具链
ROOT_FILESYSTEM="/usr/arm-linux-gnueabi/"
BUILD_HOST="x86_64-linux-gnu" # find out with uname -m
PYTHON_VERSION="3.10.8"
PYTHON_ARCHIVE="Python-$PYTHON_VERSION.tar.xz"
ROOT_DIR="$HOME/Desktop/HiLinux"
SOURCE_DIR="Python-$PYTHON_VERSION"
INSTALL_DIR="${ROOT_DIR}/libraries"

export RFS="$ROOT_FILESYSTEM"
mkdir -p $ROOT_DIR $INSTALL_DIR

ENABLE_MODULES="_ctypes zlib array cmath binascii _collections cPickle cStringIO datetime
_elementtree fcntl _functools itertools _io math _md5 operator _random select
_sha _socket _struct termios time unicodedata"

# Step 1 - Downloading Python and extracting
cd $ROOT_DIR
wget -c http://www.python.org/ftp/python/$PYTHON_VERSION/$PYTHON_ARCHIVE
tar -xf $PYTHON_ARCHIVE
cd $SOURCE_DIR

# Step 2 - Enable modules by uncommenting them in Modules/Setup.dist
for module in $ENABLE_MODULES
do
    sed "s/^#$module/$module/" -i Modules/Setup # is `-i Modules/Setup.dist` before in Python3.6
done

# Step 3 - Cross-Compile
make distclean
# 在这里添加刚才编译好的zlib
CFLAGS="-I$INSTALL_DIR/include" CPPFLAGS="-I$INSTALL_DIR/include" LDFLAGS="-L$INSTALL_DIR/lib -L$INSTALL_DIR/lib64" ./configure --host=$TARGET_HOST --build=$BUILD_HOST --prefix=$INSTALL_DIR --disable-ipv6 ac_cv_file__dev_ptmx=no ac_cv_file__dev_ptc=no ac_cv_have_long_long_format=yes --with-ensurepip=install
make -j4 # 可以加-j多核编译来加速
make install

cd $ROOT_DIR
rm -rf $SOURCE_DIR $PYTHON_ARCHIVE

$ vim compile-python.sh
$ chmod +x compile-python.sh
$ ./compile-python.sh

执行完这个脚本可以在 INSTALL_DIR/bin 中找到Python。

安装¶

按照安装 libraries 中的步骤进行安装。
