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

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’

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.

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:

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_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
