使用phpize建立php扩展（Cannot find config.m4）

php源码:/root/soft/php-5.3.4
php安装: /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下找到这个工具
来建立一个php扩展的一个框架
[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
执行了这个步骤以后你会看到这样的结果
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.
这样以后我们会在这个目录下生成一个目录叫my_module
进入这里面我们看看
[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
然后我们要修改文件顺序是
configue.m4
my_module.c
php_my_module.h
使用文本编辑器打开config.m4文件，文件内容大致如下：
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])
我这里用了后者
然后保存退出
然后在编辑
Vi 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 world/n");
}
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
my_module]# /usr/local/php/bin/phpize
