使用phpize創建php擴展（Cannot find config.m4）

php源碼:/root/soft/php-5.3.4
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下找到這個工具
來創建一個php擴展的一個框架
[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
執行了這個步驟之後你會看到這樣的結果
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.
這樣之後咱們會在這個目錄下生成一個目錄叫my_module
進入這裏面咱們看看
[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

而後咱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，文件內容大體以下：
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
根據你本身的選擇將
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])

修改爲
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])

修改爲
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])
我這裏用了後者
而後保存退出
而後在編輯
Vi my_module.c
將文件其中的下列代碼進行修改

/* 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[] */

};
在文件的最後添加下列代碼
PHP_FUNCTION(say_hello)
{
       zend_printf("hello world/n");

}
保存文件退出
而後咱們就能夠在這個目錄下使用上面的命令了
/usr/local/php/bin/phpize
執行之後會看到下面的
[root@ns my_module]# /usr/local/php/bin/phpize
