交叉编译工具链
公开版本使用可以参考这篇博文:一次搞定 Arm Linux 交叉编译 定制版本一般配置文件比较齐全,一键配置:
- 将交叉编译工具链文件夹放到对应目录(有的工具链存放目录已写入配置文件,如/opt/,更改存放文件夹可能导致无法使用)
- 进入交叉编译工具链,source environment-xxxx
- 查看交叉编译工具链是否设置成功:
arm-xxx-xxx-gcc -v arm-xxx-xxx-g++ -v
交叉编译python
- 下载python源码: Python
- 解压源码:tar -xvf Python-3.10.4.tar.xz
- 进入文件夹:cd Python-3.10.4
- 先切换到python3.10环境下,或者在本地编译python(./configure ; make),同时创建软连接将运行python链接到本地编译python(ln -s ./python /xx/bin/python),否则直接交叉编译python会报错(checking for python interpreter for cross build… configure: error: python3.10 interpreter not found)
- 交叉编译:./configure --prefix=
pwd /build --host=arm-xxx-xx --build=x86_64-linux-gnu - 编译报错:configure: error: set ac_cv_file__dev_ptmx(ac_cv_file__dev_ptc) to yes/no in your CONFIG_SITE file when cross compiling (解决方案:进入部署的arm平台,进入dev文件夹,查看是否有ptmx/ptc文件,有则设置yes否则设置no)
- 最终编译命令:
./configure --prefix=pwd /build --host=arm-xxx-xxx --build=x86_64-linux-gnu ac_cv_file__dev_ptmx=yes ac_cv_file__dev_ptc=no
make HOSTPYTHON=./hostpython HOSTPGEN=./Parser/hostpgen BLDSHARED=“arm-xxx-xxx-gcc -shared” CROSS_COMPLIE=arm-xxx-xxx- CROSS_COMPLIE_TARGET=yes HOSTARCH=arm-xxx-xxx BUILDARCH=x86_64-linux-gnu -j2
make install HOSTPYTHON=./hostpython BLDSHARED=“arm-xxx-xxx-gcc -shared” CROSS_COMPILE=arm-xxx-xxx- CROSS_COMPILE_TARGET=yes prefix=$PWD/mybuild
- 将编译好的文件拷贝到arm设备上:
adb push ./Python-3.10.4 /xxx/test/
- 进入arm设备对应目录/xxx/test/Python-3.10.4/bin/,查看python:
./python3 --version ./python3
- 可以建立软链接,链接到新编译的python
ln -s ./python3 /usr/bin/python3
