首先说下环境
python 版本： 2.7.3
/* 下载地址 */
https://www.python.org/downloads/release/python-273/
交叉编译器 arm-linux-gnueabi
gcc version 4.9.4 (Linaro GCC 4.9-2017.01)
第一步 先搞定能在ARM 环境下运行python
1. 编译python 可参考
https://www.cnblogs.com/hit-python/p/4079506.html /* 求毕业 */
以下是我的命令：
kyq@kyq:~/python/Python-2.7.3$
/* 这几步是为了编译出host的解释器 */
./configure
make python Parser/pgen
mv python hostpython
mv Parser/pgen Parser/hostpgen
make distclean
/* 给python源码打上交叉编译补丁 */
patch -p1 < Python-2.7.3-xcompile.patch
/* 交叉编译配置 */
CC=arm-linux-gnueabihf-gcc
CXX=arm-linux-gnueabihf-g++
AR=arm-linux-gnueabihf-ar
RANLIB=arm-linux-gnueabihf-ranlib
./configure --host=arm-linux-gnueabihf --prefix=/home/kyq/python/Python-2.7.3/_install/
make HOSTPYTHON=./hostpython HOSTPGEN=./Parser/hostpgen BLDSHARED="arm-linux-gnueabihf- -shared" CROSS_COMPILE=arm-linux-gnueabihf- CROSS_COMPILE_TARGET=yes
make install HOSTPYTHON=./hostpython BLDSHARED="arm-linux-gnueabihf- -shared" CROSS_COMPILE=arm-linux-gnueabihf- CROSS_COMPILE_TARGET=yes prefix=/home/kyq/python/Python-2.7.3/_install
/* 拷贝到开发板的文件系统中 */
/* 这里我是通过网络文件系统nfs 挂载的方式验证的 */
sudo cp -r _install/ /home/kyq/nfs/rootfs
在_install/bin目录下./python就进入了python环境，输入exit()就退出python。
/* 出现的问题 */
arm-linux-gnueabihf-gcc -c -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -DPy_BUILD_CORE -o Modules/python.o ./Modules/python.c

/* 解决办法 */
在/home/kyq/python-2.7.3/pyconfig.h 中 947行
找到#undef PY_FORMAT_LONG_LONG,添加一行#define PY_FORMAT_LONG_LONG “ll”
/* 出现的问题 */
Parser/pgen ./Grammar/Grammar ./Include/graminit.h ./Python/graminit.c
Parser/pgen: 1: Parser/pgen: Syntax error: word unexpected (expecting ")")
Makefile:562: recipe for target 'Parser/pgen.stamp' failed
make: *** [Parser/pgen.stamp] Error 2
/* 解决办法 */
补丁打的不对 重新打补丁去 |
