交叉编译php5

　　软件版本：php-5.4.27

　　依赖库：zlib,libxml2

　　交叉编译器：arm-hisiv200-linux-gnueabi

将交叉编译器路径添加到PATH中，我的交叉编译器目录为/usr/local/arm-hisiv200-linux/，而交叉编译器在交叉编译器目录的/bin中，在控制台输入
```
PATH=$PATH:/usr/local/arm-hisiv200-linux/bin/
```
首先先交叉编译zlib，进入zlib源码目录。
执行CC=arm-hisiv200-linux-gnueabi-gcc ./configure --shared --prefix=ZLIB_PATH(编译成功后的安装路径)
make && make install
在ZLIB_PATH中会有编译成功后的文件和配置。
然后交叉编译libxml2，进入libxml2源码目录。
执行CC=arm-hisiv200-linux-gnueabi-gcc ./configure --host=arm-hisiv200-linux-gnueabi --prefix=LIBXML2_PATH(编译成功后的安装路径)
make && make install
在LIBXML2_PATH中会有编译成功后的文件和配置。
开始交叉编译php5，进入php5源码目录。
首先先执行./buildconf --force，为了防止出现 cp:cannot stat 'sapi/cli/php.1': No such file or directory
执行./configure --host=arm-hisiv200-linux-gnueabi --enable-shared --with-zlib-dir=ZLIB_PATH --with-libxml-dir=LIBXML2_PATH --disable-phar --with-sqlite --with-pdo-sqlite --without-iconv --enable-fpm --prefix=PHP5_PATH
make && make install
编译好的php程序及配置就在PHP5_PATH中。

交叉编译nginx

　　软件版本：nginx-1.6.2

　　依赖源码：pcre,zlib(这里是需要用到它们的源码)

　　交叉编译器：arm-hisiv200-linux-gnueabi

　　linux版本：32位ubuntu(这个很重要，主要是使用32位x86系统才能进行编译成功，因为字长不一样)

　　交叉编译nginx与交叉编译php5不同就是nginx用的是依赖的库的源码，而php5用的是库文件。

在配置和编译nginx会出现很多错误，我们一个一个解决，首先我使用的configure配置如下：

#!/bin/bash

CC_PATH=/home/shanlink/Cross_compile/arm-hisiv200-linux/bin/arm-hisiv200-linux-gnueabi-gcc

CPP_PATH=/home/shanlink/Cross_compile/arm-hisiv200-linux/bin/arm-hisiv200-linux-gnueabi-g++

INSTALL_PATH=/home/shanlink/Cross_compile/nginx_ccs/

PCRE_PATH=/home/shanlink/Cross_compile/pcre-8.11/

ZLIB_PATH=/home/shanlink/Cross_compile/zlib-1.2./

CC_OPTS="-I /home/shanlink/Cross_compile/arm-hisiv200-linux/target/include/"

./configure --prefix=$INSTALL_PATH --with-zlib=$ZLIB_PATH --with-pcre=$PCRE_PATH --with-cc=$CC_PATH --with-cpp=$CPP_PATH --with-cc-opt=$CC_POTS --with-ld-opt="-L /home/shanlink/Cross_compile/arm-hisiv200-linux/target/lib/"

好的，把以上内容做成一个运行脚本，运行，出现一个错误：

checking for OS

 + Linux 3.13.--generic x86_64

checking for C compiler ... found but is not working

./configure: error: C compiler /home/shanlink/Cross_compile/arm-hisiv200-linux/bin/arm-hisiv200-linux-gnueabi-gcc is not found

解决办法就是：编辑auto/cc/name文件，在文件开头有如下一段，注释掉exit 1

if [ "$NGX_PLATFORM" != win32 ]; then

    ngx_feature="C compiler"

    ngx_feature_name=

    ngx_feature_run=yes

    ngx_feature_incs=

    ngx_feature_path=

    ngx_feature_libs=

    ngx_feature_test=

    . auto/feature

    if [ $ngx_found = no ]; then

        echo

        echo $: error: C compiler $CC is not found

        echo

        #exit         注释掉这一行

    fi

fi

再次运行我们的配置脚本，这时候出现

checking for TCP_INFO ... found

checking for accept4() ... found

checking for int size ...objs/autotest: : objs/autotest: Syntax error: word unexpected (expecting ")")

  bytes

./configure: error: can not detect int size

cat: objs/autotest.c: No such file or directory

解决方法：编辑auto/types/sizeof文件，找到

ngx_test="$CC $CC_TEST_FLAGS $CC_AUX_FLAGS \

          -o $NGX_AUTOTEST $NGX_AUTOTEST.c $NGX_LD_OPT $ngx_feature_libs"

将的$CC改为x86上使用的gcc

ngx_test="gcc $CC_TEST_FLAGS $CC_AUX_FLAGS \

          -o $NGX_AUTOTEST $NGX_AUTOTEST.c $NGX_LD_OPT $ngx_feature_libs"

再次运行我们的配置脚本，这时应该可以顺利配置完成。

执行make，这时候会出现一个错误

checking for C compiler default output file name... a.out

checking for suffix of executables...

checking whether we are cross compiling... configure: error: in `/home/shanlink/Cross_compile/pcre-8.11':

configure: error: cannot run C compiled programs.

If you meant to cross compile, use `--host'.

See `config.log' for more details.

make[]: *** [/home/shanlink/Cross_compile/pcre-8.11//Makefile] Error 1

make[]: Leaving directory `/home/shanlink/Cross_compile/nginx-1.6.'

make: *** [build] Error

这个是由于nginx在编译时会同时配置pcre并且进行编译，而由于是交叉编译，pcre的配置时需要添加--host=arm-hisiv200-linux-gnueabi，因为是由nginx自动配置的，所以我们需要手动添加此选项于pcre，然后再make，此选项添加在

文件：objs/Makefile

找到如下一段：

/home/shanlink/Cross_compile/pcre-8.11//Makefile:    objs/Makefile

    cd /home/shanlink/Cross_compile/pcre-8.11/ \

    && if [ -f Makefile ]; then $(MAKE) distclean; fi \

    && CC="$(CC)" CFLAGS="-O2 -fomit-frame-pointer -pipe " \

    ./configure --disable-shared 

将

    ./configure --disable-shared

改为

    ./configure --disable-shared --host=arm-hisiv200-linux-gnueabi(这个交叉编译器前缀填你们电脑上自己的)

如果遇到一下错误，原因是你们的linux系统是64位的，而arm上一般都是32位的，所以会有这个错误，解决办法就是重新装一个32位的linux系统。

make[]: *** [objs/src/core/ngx_slab.o] Error

make[]: Leaving directory `/home/shanlink/Cross_compile/nginx-1.6.'

make: *** [build] Error

这时候继续make，还会出现两个错误，一个是

src/os/unix/ngx_errno.c: In function 'ngx_strerror':

src/os/unix/ngx_errno.c:: error: 'NGX_SYS_NERR' undeclared (first use in this function)

src/os/unix/ngx_errno.c:: error: (Each undeclared identifier is reported only once

src/os/unix/ngx_errno.c:: error: for each function it appears in.)

src/os/unix/ngx_errno.c: In function 'ngx_strerror_init':

src/os/unix/ngx_errno.c:: error: 'NGX_SYS_NERR' undeclared (first use in this function)

make[]: *** [objs/src/os/unix/ngx_errno.o] Error

make[]: Leaving directory `/home/shanlink/Cross_compile/nginx-1.6.'

make: *** [build] Error

解决方法就是打开objs/ngx_auto_config.h,添加

#ifndef NGX_SYS_NERR

#define NGX_SYS_NERR    132

#endif

另一个错误

objs/src/event/ngx_event_accept.o: In function `ngx_event_accept':

/home/shanlink/Cross_compile/nginx-1.6./src/event/ngx_event_accept.c:: warning: warning: accept4 is not implemented and will always fail

collect2: ld returned  exit status

make[]: *** [objs/nginx] Error

make[]: Leaving directory `/home/shanlink/Cross_compile/nginx-1.6.'

make: *** [build] Error

shanlink@ubuntu:~/Cross_compile

同样的，我们需要修改objs/ngx_auto_config.h文件，在文件中加入

#ifndef NGX_HAVE_SYSVSHM

#define NGX_HAVE_SYSVSHM 1

#endif

好了，这时候make && make install就应该能编译过去了。

交叉编译squid

　　软件版本：squid-2.7-STABLE9

　　交叉编译器：arm-hisiv200-linux-gnueabi

　　系统：32位ubuntu

　　在对squid进行交叉编译时，需要用到x86版本的squid，所以我们要进行两个版本的编译。

首先编译x86版本的使用配置为
```
./configure --prefix=X86_SQUID_PATH
```
make && make install
进入到squid源码目录下的src/文件夹，有个cf_gen程序，备份起来，交叉编译时会用到。

建立一个arm-linux.cache文件，写入

ac_cv_epoll_works=

ac_cv_af_unix_large_dgram=

ac_cv_func_setresuid=

ac_cv_func_va_copy=

ac_cv_func___va_copy=

执行

#!/bin/bash

./configure --host=arm-hisiv200-linux-gnueabi --prefix=/home/shanlink/Cross_compile/squid_ccs/ --cache-file=arm-linux.cache

这时应该是能够顺利通过的

执行make，会出现一个错误
```
./cf_gen: cannot execute binary file
```
将之前备份的x86的cf_gen复制到src/目录下替换arm的
再次执行make，应该可以顺利通过编译
make install
完成
