Phpize build PHP Extension error cannot find CONFIG.M4.

First, enter the PHP source installation package directory below to execute a command:

cd /home/oldboy/tools/php-5.5.32/ext/./ext_skel --extname=redis

Then go to the extension directory, you can see the following three files, respectively, to edit:

cd redis/lsconfig.m4    redis.c    php_redis.h

Habit of getting back up before operation
Edit CONFIG.M4 First In order
Will

> dnl PHP_ARG_ENABLE(redis, whether to enable redis support,> dnl Make sure that the comment is aligned:> dnl [  --enable-redis           Enable redis support])

Revision changed to

< PHP_ARG_ENABLE(redis, whether to enable redis support,< [  --enable-redis           Enable redis support])

Save exit

Then edit REDIS.C
Add one line of code in this paragraph: Php_fe (Say_hello, NULL)

const zend_function_entry redis_functions[] = {        PHP_FE(say_hello,       NULL)        PHP_FE(confirm_redis_compiled,  NULL)           /* For testing, remove later. */        PHP_FE_END      /* Must be the last line in redis_functions[] */};

Add the following code at the end of the file:

PHP_FUNCTION(say_hello){        zend_printf("hello redis!");}

Save exit

Last edited Php_redis.h
Add one line of code in this paragraph: php_function (Say_hello)

PHP_FUNCTION(confirm_redis_compiled);   /* For testing, remove later. */PHP_FUNCTION(say_hello); /* For testing, remove later. */

Save exit

No accident at this time can execute phpize command, no error, problem solving!
