需要准备的东西:
Apache-1.3.39 for linux
Php-4.4.8 for linux
Ubuntu amd64位 PC机
6410开发板,我用的是友善之臂
交叉编译:
交叉编译呢,简单地说,就是在一个平台上生成另一个平台上的可执行代码,即使用pc上的arm linuxgcc编译器编译好代码,并安装,然后把整个安装包放到开发板的相应目录。
理论上只需在PC上编译安装arm版的apache和php即可,实际上由于在编译安装过程中需要用到某些文件,而这些文件在x86或amd64平台上无法运行的,所以在编译arm版的apache和php之前,需要先使用gcc编译x86版的apache和php。
Apache和php安装包放在/usr/local上,并且arm版的安装在apache_arm文件夹,x86版的安装在apache_test文件夹
编译安装apache
本地x86编译:
tar xvf apache_1.3.39.tar.gz
cd /usr/local/apache_1.3.39/
./configure --prefix=/usr/local/apache_test/apache --enable-module=so
出现:
Syntax error — The configuration file is used only to
define the list of included modules or to set Makefile in src
options or Configure rules, and I don’t see that at all:
`$(SRCDIR)/apaci`
default
default
no

yes

no

default
这是由于某些shell脚本文件使用了错误的interpreter,使用下面的命令就可以解决。
# rm -f /bin/sh
# ln -s /bin/bash /bin/sh
再次./configure,没问题
接着make
出错:
htpasswd.c:101:12: error: conflicting types for ‘getline’
static int getline(char *s, int n, FILE *f)
^
In file included from ../include/ap_config.h:1054:0,

make[1]: *** [build-support] Error 1
make[1]: Leaving directory `/usr/local/apache_1.3.39‘
make: *** [build] Error 2
解决方法:
这个问题是apache里自带了一个getline函数,并和stdio.h里的getline函数冲突了
gedit gedit /usr/include/stdio.h
找到getlline函数,把名字替换成parseline,保存,再make,ok,编译成功,然后记得把parseline函数改回getline
Make install也没有问题
注:(这里必须要注意:事实上,我花了将近一个星期的时间去移植,第一次移植时我是老老实实去make install了,结果在最后,我在pc上运行arm版的apache时竟然不报错,这是有问题的,因为arm linux gcc编译过的运行文件是不能在x86平台上跑的,而且x86和arm的apache能互相start和stop,由此断定肯定是安装出错了, 无奈下我全把所有安装文件全删了,重新再来一遍,但我把x86 的apache安装包备份了,事实上,x86 的apache里面有一个httpd文件在安装arm的php时需要用到,由此建议make install后把安装包备份,然后删掉)
Arm编译:
新建一个文件夹,用来存放apache for arm
mkdir /usr/local/apache_1.3.39_arm
tar xvf apache_1.3.39.tar.gz -C apache_1.3.39_arm
cd /usr/local/apache_1.3.39_arm/apache_1.3.39
CC=arm-linux-gcc ./configure --prefix=/usr/local/apache_arm/apache --enable-module=so
出错:
提示testfunc不能打开二进制文件,因为交叉编译的生成的testfunc这个工具不能在PC上执行,可以不理会它。
接着修改一个配置文件,使用上面pc机编译过的文件,
打开/usr/local/apache_1.3.39_arm/apache_1.3.39/src/main/Makefile这个文件,找 到 这 两 段 代 码
uri_delims.h
: gen_uri_delims
./gen_uri_delims >uri_delims.h
test_char.h
: gen_test_char
./gen_test_char >test_char.h
修改为
uri_delims.h: gen_uri_delims
/usr/local/apache_1.3.39/src/main/gen_uri_delims >uri_delims.h
test_char.h: gen_test_char
/usr/local/apache_1.3.39/src/main/gen_test_char >test_char.h
这里借用了刚才编译生成的本机代码里的工具
Make,出错,修改arm-linux-gcc里的stdio.h,找到getlline函数,把名字替换成parseline,保存,再make,ok,编译成功
再make install ,没问题了,然后记得把parseline函数改回getline
这样,apache for arm就安装结束了,将apache_arm打包到开发板的/usr/local,运行,应该是没有问题了。
PHP编译安装(保证apache没有问题的前提下):
X86版:
cd /usr/llocal
tar -jxvf php-4.4.8.tar.bz2
cd ./php-4.4.8/
./configure
出错:
configure: error: cannot find output from lex; giving up
apt-get install flex
再次./configure,可以了,make,也没有问题
ARM版:
cd /usr/llocal
mkdir /usr/local/php-4.4.8_arm
tar -jxvf php-4.4.8.tar.bz2 -C php-4.4.8_arm
cd ./php-4.4.8_arm/php-4.4.8
CC=arm-linux-gcc ./configure --prefix=/usr/local/apache_arm/php --with-apxs=/usr/local/apache_arm/apache/bin/apxs
报错:
Sorry, I was not able to successfully run APXS. Possible reasons:
1. Perl is not installed;
2. Apache was not compiled with DSO support (--enable-module=so);
3. ‘apxs‘ is not in your path. Try to use --with-apxs=/path/to/apxs
The output of /usr/local/apache-arm11/apache/bin/apxs follows
Use of assignment to $[ is deprecated at /usr/local/apache-arm11/apache/bin/apxs line 86.
/usr/local/apache-arm11/apache/bin/httpd: /usr/local/apache-arm11/apache/bin/httpd: cannot execute binary file
apxs:Error: Sorry, no DSO support for Apache available
apxs:Error: under your platform. Make sure the Apache
apxs:Error: module mod_so is compiled into your server
apxs:Error: binary `/usr/local/apache-arm11/apache/bin/httpd‘.
configure: error: Aborting
解决方法:
在/usr/local/php-4.4.8_arm/php-4.4.8/configure找到checking for Apache 1.x module support via DSO through APXS,把下面的代码注释掉
# $APXS -q CFLAGS >/dev/null 2>&1
# if test "$?" != "0"; then
# echo "$ac_t""" 1>&6
# echo "$ac_t""" 1>&6
# echo "$ac_t""Sorry, I was not able to successfully run APXS. Possible reasons:" 1>&6
# echo "$ac_t""" 1>&6
# echo "$ac_t""1. Perl is not installed;" 1>&6
# echo "$ac_t""2. Apache was not compiled with DSO support (--enable-module=so);" 1>&6
# echo "$ac_t""3. ‘apxs‘ is not in your path. Try to use --with-apxs=/path/to/apxs" 1>&6
# echo "$ac_t""The output of $APXS follows" 1>&6
# $APXS -q CFLAGS
# { echo "configure: error: Aborting" 1>&2; exit 1; }
# fi
搜索“can not run test program while cross compiling”,会搜索到很多个这样的结果:
{ echo "configure: error: can not run test program while cross compiling" 1>&2; exit 1; }
把它们都改为
{ echo "configure: error: can not run test program while cross compiling" 1>&2; }
这样做的目的是直接无视交叉编译测试程序错误。
./config没问题了
Make
出错:
In file included from /usr/local/php-4.4.8-arm/php-4.4.8/sapi/apache/sapi_apache.c:24:0:
/usr/local/php-4.4.8-arm/php-4.4.8/sapi/apache/php_apache_http.h:22:19: fatal error: httpd.h: No such file or directory
compilation terminated.
make: *** [sapi/apache/sapi_apache.lo] Error 1
解决方法:
使用PC机编译的PHP文件
gedit /usr/local/php-4.4.8_arm/php-4.4.8/Makefile
install-pear-packages: $(top_builddir)/sapi/cli/php
@$(top_builddir)/sapi/cli/php $(PEAR_INSTALL_FLAGS) /usr/local/php-4.4.8-arm/php-4.4.8/pear/install-pear.php -d "$(peardir)" -b "$(bindir)" /usr/local/php-4.4.8-arm/php-4.4.8/pear/packages/*.tar
修改为:
: /usr/local/php-4.4.8/sapi/cli/php
@/usr/local/php-4.4.8/sapi/cli/php $(PEAR_INSTALL_FLAGS) /usr/local/php-4.4.8-arm/php-4.4.8/pear/install-pear.php -d "$(peardir)" -b "$(bindir)" /usr/local/php-4.4.8-arm/php-4.4.8/pear/packages/*.tar
并修改相应头文件的绝对路径,不然会提示某些头文件找不到
gedit /usr/local/php-4.4.8_arm/php-4.4.8/sapi/apache/mod_php4.c
#include "/usr/local/apache-arm11/apache/include/http_conf_globals.h"
gedit /usr/local/php-4.4.8_arm/php-4.4.8/sapi/apache/php_apache_http.h
#include "/usr/local/apache_arm/apache/include/httpd.h"
#include "/usr/local/apache_arm/apache/include/http_config.h"
# include "/usr/local/apache_arm/apache/include/ap_compat.h"
#include "/usr/local/apache_arm/apache/include/http_core.h"
#include "/usr/local/apache_arm/apache/include/http_main.h"
#include "/usr/local/apache_arm/apache/include/http_protocol.h"
#include "/usr/local/apache_arm/apache/include/http_request.h"
#include "/usr/local/apache_arm/apache/include/http_log.h"
#include "/usr/local/apache_arm/apache/include/util_script.h"
反正是缺什么补什么,那些头文件都在/usr/local/apache_arm/apache/include里
Make终于可以了:如下
Build complete.
(It is safe to ignore warnings about tempnam and tmpnam).
Make install
出错:
root@Da:/usr/local/php-4.4.8_arm/php-4.4.8# make install
Installing PHP SAPI module: apache

make: *** [install-sapi] Error 1
apache_arm/apache/bin/httpd是运行在arm平台上的,当然不能在x86上跑,明白这点,果断把一开始安装的x86 apache的httpd拷贝过来,不要忘记,备份好arm的httpd,安装完后还要覆盖回来,我当初就是由于忘了覆盖回来,打包好的安装文件在6410上运行,结果报错如下:
输入/usr/local/apache-arm11/apache/bin/apachectl start
报错:
/usr/local/apache_arm/apache/bin/httpd: line1: elf: not found
/usr/local/apache_arm/apache/bin/httpd: line2: syntax error: unexpected ”(”
明显,这个是x86的httpd当然也不能在arm平台上跑,绕的路真是太多了。
再次make install,还是不行,报错如下
make[1]: *** No rule to make target `usr/local/php-4.4.8/sapi/cli/php‘, needed by `install-pear-packages‘. Stop.
make: *** [install-pear] Error 2
usr/local/php-4.4.8/sapi/cli/php,奇葩错误,usr前竟然少了个/,没办法,gedit /usr/local/php-4.4.8-arm/php-4.4.8/Makefile改回来,再次maike install,出现
Php cannot execute binary file,把usr/local/php-4.4.8/sapi/cli/php拷贝到php-4.4.8_arm
/php-4.4.8/sapi/cli/里,注意备份php,make install,成功,同理,把备份的arm版php拷贝回来,不然在开发板上也是跑不了的。
这就是apache+php全部的移植过程
剩下的就是如何修改配置文件将apache和php关联起来,百度一搜大把,前辈们还是很给力的,我就不写了。之所以要写这一篇文章,一是记录,二是网上的教程太多太乱,遇到的问题也因人而异,当然,这文章记录的问题也不一定每个人都会遇到,而遇到的问题这篇文章也不一定有,但我想说的是,无论遇到什么问题,不要放弃,耐心分析,善于百度,问题总可以解决的。
移植过程主要参考
以及大量的博客
