为php编译xcache模块的时候，需要运行phpize
得到了一个错误
#/usr/local/php/bin/phpize
Configuring for:
PHP Api Version: 20041225
Zend Module Api No: 20060613
Zend Extension Api No: 220060519
Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF
environment variable is set correctly and then rerun this script.
通过安装 autoconf 可以解决
centos下执行 yum install autoconf 即可
Ubuntu下执行 apt-get install autoconf 即可
17）
# /usr/local/php/bin/phpize
Cannot find config.m4.
Make sure that you run '/usr/local/php/bin/phpize' in the top level source directory of the module
修改方法：
[root@centos lnmp]# cd php-5.2.14ext/
[root@centos ext]# ./ext_skel --extname=my_module
Creating directory my_module
Creating basic files: config.m4 config.w32 .cvsignore my_module.c php_my_module.h CREDITS EXPERIMENTAL tests/001.phpt my_module.php [done].
To use your new extension, you will have to execute the following steps:
1. $ cd ..
2. $ vi ext/my_module/config.m4
3. $ ./buildconf
4. $ ./configure --[with|enable]-my_module
5. $ make
6. $ ./php -f ext/my_module/my_module.php
7. $ vi ext/my_module/my_module.c
8. $ make
Repeat steps 3-6 until you are satisfied with ext/my_module/config.m4 and
step 6 confirms that your module is compiled into PHP. Then, start writing
code and repeat the last two steps as often as necessary.
[root@centos ext]# cd my_module/
[root@centos my_module]# vim config.m4
根据你自己的选择将
dnl PHP_ARG_WITH(my_module, for my_module support,
dnl Make sure that the comment is aligned:
dnl [ --with-my_module Include my_module support])
修改成
PHP_ARG_WITH(my_module, for my_module support,
Make sure that the comment is aligned:
[ --with-my_module Include my_module support])
或者将
dnl PHP_ARG_ENABLE(my_module, whether to enable my_module support,
dnl Make sure that the comment is aligned:
dnl [ --enable-my_module Enable my_module support])
修改成
PHP_ARG_ENABLE(my_module, whether to enable my_module support,
Make sure that the comment is aligned:
[ --enable-my_module Enable my_module support])
[root@centos my_module]# vim my_module.c
　　将文件其中的下列代码进行修改
/* Every user visible function must have an entry in my_module_functions[].
*/
function_entry my_module_functions[] = {
　　　　PHP_FE(say_hello,　　　 NULL)　/* ?添加着一行代码 */
　　　　PHP_FE(confirm_my_module_compiled,　　　NULL) /* For testing, remove later. */
　　　　{NULL, NULL, NULL}　　　/* Must be the last line in my_module_functions[] */
};
　　在文件的最后添加下列代码
PHP_FUNCTION(say_hello)
{
　　　　zend_printf("hello sdomain!");
}
再修改：php_sdomain.h
vi php_sdomain.h
在PHP_FUNCTION(confirm_my_module_compiled ); /* For testing, remove later. */ 这行的下面添加一行：
PHP_FUNCTION(say_hello); /* For testing, remove later. */
　　保存文件退出
　　然后我们就可以在这个目录下使用上面的命令了
　　/usr/local/php/bin/phpize
　　执行以后会看到下面的
　　[root@ns sdomain]# /usr/local/php/bin/phpize
　　Configuring for:
　　PHP Api Version:　　　　 20020918
　　Zend Module Api No:　　　20020429
　　Zend Extension Api No:　 20050606
　　[root@ns sdomain]#
　　然后执行./configure --with-php-config=/usr/local/php/bin/php-config
　　然后执行make
　 make install
然后他会把对应的so文件生成放到PHP安装目录下面的一个文件夹，并提示在在什么地方，然后再把里面的SO文件拷到你存放SO文件的地方
　　即你在php.ini里面的extension_dir所指定的位置
　　最后一步是你在php.ini文件中打开这个扩展
　　extension=sdomain.so
　　然后
　　重新起动apache
