使用phpize建立php擴(kuò)展（Cannot find config.m4）

php源碼:/root//php-5.5.31
php安裝: /usr/local/php

[root@ns root]# phpize
Cannot find config.m4.
Make sure that you run '/usr/local/php/bin/phpize' in the top level source directory of the module

[root@ns root]# phpize
Cannot find config.m4.
Make sure that you run '/usr/local/php/bin/phpize' in the top level source directory of the module

在/usr/local/src/php-4.3.5/ext下找到這個(gè)工具
來建立一個(gè)php擴(kuò)展的一個(gè)框架
[root@ns ext]#cd /root/soft/php-5.3.4/ext/
[root@ns ext]# ./ext_skel --extname=my_module
Creating directory my_module
Creating basic files: config.m4 .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
執(zhí)行了這個(gè)步驟以后你會(huì)看到這樣的結(jié)果
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.
這樣以后我們會(huì)在這個(gè)目錄下生成一個(gè)目錄叫my_module
進(jìn)入這里面我們看看
[root@ns ext]# cd my_module/
[root@ns my_module]# ls
config.m4  EXPERIMENTAL          my_module.php    tests
CREDITS    my_module.c  php_my_module.h

然后我們要修改文件順序是
configue.m4
my_module.c
php_my_module.h

使用文本編輯器打開config.m4文件，文件內(nèi)容大致如下：
dnl $Id$d
dnl config.m4 for extension my_module
dnl don't forget to call PHP_EXTENSION(my_module)
dnl Comments in this file start with the string 'dnl'.
dnl Remove where necessary. This file will not work
dnl without editing.
dnl If your extension references something external, use with:
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])

dnl Otherwise use enable:
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])

if test "$PHP_MY_MODULE" != "no"; then
  dnl If you will not be testing anything external, like existence of

  dnl headers, libraries or functions in them, just uncomment the

  dnl following line and you are ready to go.
  dnl Write more examples of tests here...
  PHP_EXTENSION(my_module, $ext_shared)

Fi
根據(jù)你自己的選擇將
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])

或者將
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])
我這里用了后者
然后保存退出
然后在編輯
Vi my_module.c
將文件其中的下列代碼進(jìn)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)  /* ?添加著一行代碼 */

        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碼
PHP_FUNCTION(say_hello)
{
        zend_printf("hello world/n");

}
保存文件退出
然后我們就可以在這個(gè)目錄下使用上面的命令了
/usr/local/php/bin/phpize
執(zhí)行以后會(huì)看到下面的
[root@ns my_module]# /usr/local/php/bin/phpize

PHP Api Version:         20020918
Zend Module Api No:      20020429

[root@ns my_module]#
然后執(zhí)行./configure --enable-my_module --with-apxs=/usr/local/apache/bin/apxs --with-php-config=/usr/local/php/bin/php-config
我們?cè)诎惭b以后的php的bin目錄下的可以找到這個(gè)文件的
php-config 和phpize
這一步驟一定要注意你的apache的apxs放在哪里了
然后執(zhí)行make
你會(huì)看到出現(xiàn)錯(cuò)誤了你重新定義了函數(shù)我們前面的
這個(gè)你在回頭改一下這個(gè)文件把原來的函數(shù)刪除掉在生成的文件里面會(huì)有同樣的函數(shù)
你在加入你的代碼
就可以通過了
這個(gè)時(shí)候會(huì)在當(dāng)前的目錄下生成一個(gè)目錄叫modules他的下面就放著你要的
my_module.so文件
cp modules/my_module.so /usr/local/php/ext/
這里需要你先設(shè)置你的php的擴(kuò)展目錄的在
在php.ini里面
通過extension_dir
最后一不是你在php.ini文件中打開這個(gè)擴(kuò)展
extension=my_module.so
然后
重新起動(dòng)apache
用phpinfo來察看一下ok了
