本文章为各位介绍解决编译php memcached扩展的问题:php_libmemcached_compat.h:5:40:错误:libmemcached-1.0/memcached.h:没有那个文件或目录,希望文章对各位有帮助.

服务器是Centos6 64，PHP5.4.23,需要安装php memcached扩展,尝试使用pecl安装:

1. # yum install libmemcached libmemcached-devel zlib-devel 
2. # yum -y install php-pear 
3. # pecl install memcached 

但出现错误:在包含自 /var/tmp/memcached/php_memcached.h:22 的文件中,从 /var/tmp/memcached/php_memcached.c:47:

/var/tmp/memcached/php_libmemcached_compat.h:5:40:错误:libmemcached-1.0/memcached.h:没有那个文件或目录.

上面明显php_libmemcached_compat.h文件中找不到memcached.h,于是下载文件包,一看究竟:

1. # wget http://pecl.php.net/get/memcached 
2. # mv memcached memcached.tar.gz 
3. # tar zxf memcached.tar.gz 
4. # cd memcached-2.2.0b1/ 
5. # vi php_libmemcached_compat.h 
6.   #ifndef PHP_LIBMEMCACHED_COMPAT 
7.   #define PHP_LIBMEMCACHED_COMPAT 
8.    
9.   /* this is the version(s) we support */ 
10.   #include <libmemcached/memcached.h> 

看到上面包含libmemcached/memcached.h,但事实上memcached.h文件位于:

1. # find /usr -name memcached.h 
2. /usr/include/libmemcached/memcached.h 

那么修改上面的路径为正常路径:

1. #ifndef PHP_LIBMEMCACHED_COMPAT 
2. #define PHP_LIBMEMCACHED_COMPAT 
3. --phpfensi.com  
4. /* this is the version(s) we support */ 
5. #include </usr/include/libmemcached/memcached.h> 

保存后,使用phpize来编译:

configure: error: no, sasl.h is not available. Run configure with --disable-memcached-sasl to disable this check cyrus-sasl-devel

只好加上 --disable-memcached-sasl,重新进行,但依然出现错误:

1. # ./configure --disable-memcached-sasl 
2. ...省略... 
3. In file included from /root/download/memcached-2.2.0b1/php_memcached_private.h:28, 
4.                  from /root/download/memcached-2.2.0b1/php_memcached.c:26: 
5. /root/download/memcached-2.2.0b1/php_libmemcached_compat.h:53: 错误：expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘php_memcached_instance_st’ 
6. ...省略... 

看来此路不通,只有手动编译libmemcached来尝试了,下面是手动编译libmemcached和php memcached扩展.

1.先卸载yum安装的libmemcached

# yum remove libmemcached libmemcached-devel

2.下载源码包

1. # cd .. 
2. # wget https://launchpad.net/libmemcached/1.0/1.0.17/+download/libmemcached-1.0.17.tar.gz 
3. # tar zxf libmemcached-1.0.17.tar.gz 
4. # cd libmemcached-1.0.17 
5. # ./configure 
6. # make 
7. # make install 

成功安装libmemcached.

3.接下来安装memcached,先查找memcached.h头文件在哪里,需要在php_libmemcached_compat.h设置正确的include路径.

1. # cd ../memcached-2.2.0b1 
2. # find / -name memcached.h 
3. /root/download/libmemcached-1.0.17/libmemcached/memcached.h 
4. /root/download/libmemcached-1.0.17/libmemcached-1.0/struct/memcached.h 
5. /root/download/libmemcached-1.0.17/libmemcached-1.0/memcached.h 
6. /root/download/libmemcached-1.0.17/libtest/memcached.h 
7. /root/download/mysql-5.6.15/plugin/innodb_memcached/daemon_memcached/daemon/memcached.h 
8. /usr/local/include/libmemcached/memcached.h 
9. /usr/local/include/libmemcached-1.0/struct/memcached.h 
10. /usr/local/include/libmemcached-1.0/memcached.h 

4.修改memcached-2.2.0b1下的php_libmemcached_compat.h文件中include路径为正确路径:

1. #ifndef PHP_LIBMEMCACHED_COMPAT 
2. #define PHP_LIBMEMCACHED_COMPAT 
3.  
4. /* this is the version(s) we support */ 
5. #include </usr/local/include/libmemcached/memcached.h> 

5.开始编译安装php memcached扩展:

1. # phpize 
2. # ./configure  
3. # make 
4. ...省略... 
5. Build complete. 
6. Don't forget to run 'make test'. 
7.  
8. # make install 
9. Installing shared extensions: /usr/lib64/php/modules/ 
10.  

6. 查看是否已生成了memcached.so:

1. # ls /usr/lib64/php/modules/ 
2.  
3. bcmath.so    gd.so        memcached.so         mysql.so       phar.so     sysvsem.so  xcache.so     xsl.so 
4. curl.so      json.so      memcache.so          pdo_mysql.so   posix.so    sysvshm.so  xmlreader.so  zip.so 
5. dom.so       mbstring.so  mysqli.so            pdo.so         sqlite3.so  tidy.so     xmlrpc.so 
6. fileinfo.so  mcrypt.so    mysqlnd_memcache.so  pdo_sqlite.so  sysvmsg.so  wddx.so     xmlwriter.so
