When compiling the xcache module for php, you need to run phpize
Got an error
#/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.
This can be solved by installing autoconf
Execute yum install autoconf under centos
Under Ubuntu, execute apt-get install autoconf
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
Modification method:
[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
According to your own choice, place
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])
Modify to
PHP_ARG_WITH(my_module, for my_module support,
Make sure that the comment is aligned:
[ --with-my_module Include my_module support])
Or replace
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])
Modify to
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
Modify the following code in the file
/* Every user visible function must have an entry in my_module_functions[].
*/
function_entry my_module_functions[] = {
PHP_FE(say_hello,　 NULL)　/* ?Add a line of code */
PHP_FE(confirm_my_module_compiled,　NULL) /* For testing, remove later. */
{NULL, NULL, NULL}　 /* Must be the last line in my_module_functions[] */
};
Add the following code at the end of the file
PHP_FUNCTION(say_hello)
{
zend_printf("hello sdomain!");
}
Modify again: php_sdomain.h
vi php_sdomain.h
Add a line below the line PHP_FUNCTION(confirm_my_module_compiled); /* For testing, remove later. */:
PHP_FUNCTION(say_hello); /* For testing, remove later. */
Save file and exit
Then we can use the above command in this directory
/usr/local/php/bin/phpize
After execution, you will see the following
[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]#
Then execute ./configure --with-php-config=/usr/local/php/bin/php-config
Then execute make
make install
Then he will generate the corresponding so file and put it in a folder under the PHP installation directory, and prompt where it is, and then copy the SO file inside to the place where you store the SO file
That is, the location specified by extension_dir in php.ini
The final step is for you to open the extension in your php.ini file
extension=sdomain.so
Then
Restart apache
