Solve the problem of compiling PHP memcached extensions: PHP

This article introduces you to solve the problem of compiling PHP memcached extensions: php_libmemcached_compat.h:5:40: Error: libmemcached-1.0/ Memcached.h: Without that file or directory, I hope the article will help you.

   

The server is CENTOS6 64,php5.4.23, and you need to install the PHP memcached extension

Attempt to install using PECL:
# yum Install libmemcached libmemcached-devel zlib-devel
# yum-y Install Php-pear
# pecl Install memcached

But an error occurred:
In the file containing the/var/tmp/memcached/php_memcached.h:22, from/var/tmp/memcached/php_memcached.c:47:
/VAR/TMP/MEMCACHED/PHP_LIBMEMCACHED_COMPAT.H:5:40: Error: libmemcached-1.0/memcached.h: no file or directory

The above obvious php_libmemcached_compat.h file can not find the memcached.h, so download the package, a look at the following:
# wget Http://pecl.php.net/get/memcached
# MV Memcached memcached.tar.gz
# tar zxf memcached.tar.gz
# CD MEMCACHED-2.2.0B1/
# VI Php_libmemcached_compat.h
#ifndef Php_libmemcached_compat
#define Php_libmemcached_compat
19
/* This is the version (s) We support * *
#include <libmemcached/memcached.h>

See above contains libmemcached/memcached.h, but in fact memcached.h files are located at:
# Find/usr-name Memcached.h
/usr/include/libmemcached/memcached.h

Then modify the path above to the normal path:

#ifndef Php_libmemcached_compat
#define Php_libmemcached_compat
19
/* This is the version (s) We support * *
#include </usr/include/libmemcached/memcached.h>

After saving, use Phpize to compile:

Configure:error:no, Sasl.h is not available. Run Configure with--DISABLE-MEMCACHED-SASL to disable this check
Cyrus-sasl-devel

Had to add the--DISABLE-MEMCACHED-SASL, again, but there are still errors:
#./configure--DISABLE-MEMCACHED-SASL
... Omitted...
In file included From/root/download/memcached-2.2.0b1/php_memcached_private.h:28,
FROM/ROOT/DOWNLOAD/MEMCACHED-2.2.0B1/PHP_MEMCACHED.C:26:

... Omitted...

It seems blocked, only manually compiled libmemcached to try.

The following is a manual compilation of libmemcached and PHP memcached extensions

1. Uninstall the libmemcached of the Yum installation first

# yum Remove libmemcached libmemcached-devel

2. Download the source package

# CD ...
# wget https://launchpad.net/libmemcached/1.0/1.0.17/+download/libmemcached-1.0.17.tar.gz
# tar zxf libmemcached-1.0.17.tar.gz
# CD libmemcached-1.0.17
#./configure
# make
# make Install

Successfully installed libmemcached.

3. Next install memcached, first find memcached.h header file where, need to set the correct include path in php_libmemcached_compat.h

# CD ... /memcached-2.2.0b1
# Find/-name Memcached.h
/root/download/libmemcached-1.0.17/libmemcached/memcached.h
/root/download/libmemcached-1.0.17/libmemcached-1.0/struct/memcached.h
/root/download/libmemcached-1.0.17/libmemcached-1.0/memcached.h
/root/download/libmemcached-1.0.17/libtest/memcached.h
/root/download/mysql-5.6.15/plugin/innodb_memcached/daemon_memcached/daemon/memcached.h
/usr/local/include/libmemcached/memcached.h
/usr/local/include/libmemcached-1.0/struct/memcached.h
/usr/local/include/libmemcached-1.0/memcached.h

4. Modify the include path in the Php_libmemcached_compat.h file under Memcached-2.2.0b1 to the correct path:

#ifndef Php_libmemcached_compat
#define Php_libmemcached_compat
19
/* This is the version (s) We support * *
#include </usr/local/include/libmemcached/memcached.h>

5. Start compiling and installing PHP memcached extensions:

# phpize
#./configure
# make
... Omitted...
Build complete.
Don ' t forget to run ' make test '.

# make Install
Installing Shared extensions:/usr/lib64/php/modules/

6. See if memcached.so has been generated:

# ls/usr/lib64/php/modules/
