交叉编译python2.7.7

2023年1月12日 427次阅读

一、python下载网址： http://www.python.org/ftp/python/

二、python的交叉编译依赖openssl ，openssl的下载网址： https://www.openssl.org/source/old/

三、编译：
1、交叉编译 openssl-1.0.2g

# /home/sw/openssh/openssl-1.0.2g
# mkdir build
#  ./config --prefix=/home/sw/openssh/old/openssl-1.0.2g/build  os/compiler:aarch64-linux-gnu-gcc  -fPIC
# make
# make -i install

 

2、交叉编译python

# tar -xvf Python-2.7.7.tar.xz
# cd Python-2.7.7
# mkdir arm_build （存放交叉编译的信息）
# mkdir local_build （存放本地编译的信息）

# cd Python-2.7.7/

 

(1)首先本地编译pgen

# ./configure --prefix=/home/carrie/python/Python-2.7.7/local_build/
# make 
# make install
# cp Parser/pgen  arm_build/
# make clean

 

(2)交叉编译python

# vi Modules/_ctypes/libffi/fficonfig.py.in 
ffi_platforms = {
        'AARCH64': ['src/aarch64/ffi.c', 'src/aarch64/sysv.S'],  ##增加这一行
        'MIPS_IRIX': ['src/mips/ffi.c', 'src/mips/o32.S', 'src/mips/n32.S'],
# ./configure --prefix=/Python-2.7.7/arm_build/ --host=aarch64-linux-gnu --build=x86_64-linux-gnu CC=aarch64-linux-gnu-gcc AR=aarch64-linux-gnu-ar LD=aarch64-linux-gnu-ld ac_cv_file__dev_ptmx=no ac_cv_file__dev_ptc=no --disable-ipv6

# vim Makefile
　　77 LDFLAGS= -L/home/sw/openssh/old/openssl-1.0.2g/build/lib #找到LDFLAGS，在LDFLAGS后面增加这一串字符 
# make 
# make -i install

 

四、编译过程中遇到的错误：

（1）#./configure –prefix=/home/python/Python-2.7.7/build/ –host=aarch64-linux-gnu CC=aarch64-linux-gnu-gcc AR=aarch64-linux-gnu-ar –without-gcc

checking build system type… x86_64-unknown-linux-gnu
checking host system type… aarch64-unknown-linux-gnu
configure: error: Cross compiling required –host=HOST-TUPLE and –build=ARCH

原因：缺少–build的设置

解决方法：#./configure 后面加上 “–build=x86_64-linux-gnu “

 

（2）#./configure –prefix=/home/python/Python-2.7.7/build/ –host=aarch64-linux-gnu –build=x86_64-linux-gnu CC=aarch64-linux-gnu-gcc AR=aarch64-linux-gnu-ar –without-gcc

Fatal: You must get working getaddrinfo() function.
or you can specify “–disable-ipv6”.

解决方法：./configure 后面加上 “–disable-ipv6”

 

（3）# ./configure –prefix=/home/python/Python-2.7.7/build/ –host=aarch64-linux-gnu –build=x86_64-linux-gnu CC=aarch64-linux-gnu-gcc AR=aarch64-linux-gnu-ar –disable-ipv6

checking for /dev/ptmx… not set
configure: error: set ac_cv_file__dev_ptmx to yes/no in your CONFIG_SITE file when cross compiling

解决方法： ./configure后面加上 “ac_cv_file__dev_ptmx=no”

 

（4）#./configure –prefix=/home/python/Python-2.7.7/build/ –host=aarch64-linux-gnu –build=x86_64-linux-gnu CC=aarch64-linux-gnu-gcc AR=aarch64-linux-gnu-ar –disable-ipv6 ac_cv_file__dev_ptmx=no

checking for /dev/ptc… not set
configure: error: set ac_cv_file__dev_ptc to yes/no in your CONFIG_SITE file when cross compiling

解决方法：./configure后面加上 “ac_cv_file__dev_ptc=no”

 

（5）编译出错：

# make

make[1]: Leaving directory ‘/home/python/Python-2.7.7’
Parser/pgen ./Grammar/Grammar Include/graminit.h Python/graminit.c
Parser/pgen: 1: Parser/pgen: Syntax error: “(” unexpected
Makefile:616: recipe for target ‘Include/graminit.h’ failed
make: *** [Include/graminit.h] Error 2

解决方法：编译Parser/pgen ：

# ./configure

# make python Parser/pgen

# cp Parser/pgen build/Parser/

 

（6）交叉编译产生的错误及解决方法：

#make
