Description:
------------
Here is my phpize and ./configure
phpize
./configure --prefix=/opt/php \
--with-libdir=lib64 \
--enable-memcached=shared \
--enable-memcached-igbinary \
--with-libmemcached-dir=/opt/libmemcached


When I run 'make', the following error occurs:
/usr/src/redhat/BUILD/memcached-1.0.1/php_memcached.c: In 
function 'php_memc_zval_to_payload':
/usr/src/redhat/BUILD/memcached-1.0.1/php_memcached.c:2002: 
error: too few arguments to function 'php_json_encode'
/usr/src/redhat/BUILD/memcached-1.0.1/php_memcached.c: In

error: too few arguments to function 'php_json_decode'
/usr/src/redhat/BUILD/memcached-1.0.1/php_memcached.c: In 
function 'php_memc_do_result_callback':
/usr/src/redhat/BUILD/memcached-1.0.1/php_memcached.c:2328: 
warning: assignment discards qualifiers from pointer target 
type

warning: assignment discards qualifiers from pointer target 
type
make: *** [php_memcached.lo] Error 1
error: Bad exit status from /var/tmp/rpm-tmp.34373 (%build)


I found that the 'php_json_encode' requires 3 parameters 
while 'php_json_decode' requires 5 parameters:

/opt/php/include/php/ext/json/php_json.h:PHP_JSON_API void 
php_json_encode(smart_str *buf, zval *val, int options 
TSRMLS_DC);


/opt/php/include/php/ext/json/php_json.h:PHP_JSON_API void 
php_json_decode(zval *return_value, char *str, int str_len, 
zend_bool assoc, long depth TSRMLS_DC);

But in 'php_memcached.c', there are not enough parameter 
passed.
 php_json_encode(&buf, value TSRMLS_CC);
 php_json_decode(value, payload, payload_len, 0 TSRMLS_CC);

I am seeing this very behavior on FreeBSD 8.0 while trying to upgrade from PHP 5.2.x to 5.3.2 using the ports system. I get the compile error with or without igbinary support turn on at ./configure time.

The JSON encode and decode functions do indeed require more arguments as GCC states. The following patch addresses the issue. The use of 512 as the depth parameter was taken from the PHP JSON manual and may need to be changed to a constant, if available. I hope this helps someone out there in the same situation as I found myself:

Thanks for the patch andy at siliconlandmark dot com.

Also had the same compile problem when igbinary was enabled. Patch fixed this.

This issue is addressed in pecl-memcached 1.0.2. This ticket should probably be closed.
 [2010-07-21 04:11 UTC] imwxyz at gmail dot com 
There is new issue with php 5.2.13，when run 'make', 
error 
occurs:
too many arguments to function to function 'php_json_encode'
too many arguments to function to function 
'php_json_dencode'

in php_json.h, the definition is
PHP_JSON_API void php_json_encode(smart_str *buf, zval *val 
TSRMLS_DC);
PHP_JSON_API void php_json_decode(zval *return_value, char 
*buf, int buf_len, zend_bool assoc TSRMLS_DC);

so need the old php_memcached.c
