交叉编译libxml2 zlib-1.2.11

https://blog.csdn.net/c1194758555/article/details/73888960

1. 下载libxml2-2.9.4.tar.gz

http:///sources/libxml2-2.9.4.tar.gz

2. 配置并编译libxml

$ ./configure --prefix=$work --host=arm-chy-linux-gnueabihf CC=arm-chy-linux-gnueabihf-gcc CXX=arm-chy-linux-gnueabihf-g++

$ make

/home/chy/x-tools/arm-chy-linux-gnueabihf/lib/gcc/arm-chy-linux-gnueabihf/5.4.0/../../../../arm-chy-linux-gnueabihf/bin/ld: cannot find -lz
collect2: error: ld returned 1 exit status

出现上述错误，则按下面步骤交叉编译libz：

① 下载zlib-1.2.11.tar.gz

http://www./zlib-1.2.11.tar.gz

②  配置环境变量及zlib

$ export work=/home/chy/mys/meas-build/meas-arm //安装目录

$  export CC=/home/chy/x-tools/arm-chy-linux-gnueabihf/bin/arm-chy-linux-gnueabihf-gcc

$ ./configure --prefix=$work 

③编译并安装

$ make && make install

重新配置并编译libxml

$ ./configure --prefix=$work --host=arm-linux-gnueabihf CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++ Z_CFLAGS=-I/home/chy/mys/meas-build/meas-arm/include Z_LIBS=-L/home/chy/mys/meas-build/meas-arm/lib LDFLAGS=-L/home/chy/mys/meas-build/python-arm/lib

/usr/include/python2.7/pyconfig.h:24:54: fatal error: arm-linux-gnueabihf/python2.7/pyconfig.h: No such file or directory

出现上述错误，则按照下述步骤操作。

(1)交叉编译Python-2.7.13.tgz

①下载链接：

https://www./ftp/python/2.7.13/Python-2.7.13.tgz

②建立环境变量

$  export work=/home/chy/mys/meas-build/python-arm/

③配置并编译PC版python

$ mkdir ./build-pc

$ cd build-pc

$ ../configure

$ make python Parser/pgen

④配置并安装arm版的python

$ mkdir build-arm

$ cd build-arm

$ ../configure --host=arm-linux-gnueabihf --build=x86_64-linux-gnu --prefix=/home/xpf/code/python-arm/ --disable-ipv6 ac_cv_file__dev_ptmx=no ac_cv_file__dev_ptc=no ac_cv_have_long_long_format=yes PGEN_FOR_BUILD=../build-pc/Parse/pgen

$ make

$ make isntall -i

(2)配置交叉编译链

$ sudo vim /usr/include/python2.7/pyconfig.h

把交叉编译得到的pyconfig.h复制到交叉编译器的arm-chy-linux-gnueabihf/lib/gcc/arm-chy-linux-gnueabihf/5.4.0/include/arm-chy-linux-gnueabihf/目录下

$ cp python-arm/include/python2.7/pyconfig.h /opt/gcc-linaro-4.9-2016.02-x86_64_arm-linux-gnueabihf/lib/gcc/arm-linux-gnueabihf/4.9.4/include/

$ sudo gedit /usr/include/python2.7/pyconfig.h

修改include <armlinux-gnueabihf/python2.7/pyconfig.h>为include <arm-chy-linux-gnueabihf/python2.7/pyconfig.h>

$ sudo cp -rf python-arm/lib/* /opt/gcc-linaro-4.9-2016.02-x86_64_arm-linux-gnueabihf/lib

交叉编译python2.7得到的库文件，添加到交叉编译链的/lib目录中。

3. 重新配置并编译安装

$ ./configure --prefix=$work --host=arm-chy-linux-gnueabihf CC=arm-chy-linux-gnueabihf-gcc CXX=arm-chy-linux-gnueabihf-g++ Z_CFLAGS=-I/home/chy/mys/meas-build/meas-arm/include Z_LIBS=-L/home/chy/mys/meas-build/meas-arm/lib LDFLAGS=-L/home/chy/mys/meas-build/python-arm/lib CPPFLAGS=-I/home/chy/mys/meas-build/python-arm/include 

$ make && make install
