Question

I have installed drupal on my localhost. It worked well 2 months ago, but now something happened and I don’t know why. I’ll be very grateful if you can help me. Thanks in advance.

The full error looks like this:

Fatal error: Class ‘Memcache’ not
found in
/srv/www/htdocs/modules/memcache/dmemcache.inc
on line 177

1) php -m gives this:

[PHP Modules]
bz2

json
libxml

Reflection session SimpleXML SPL

[Zend Modules]

2) memcached is installed through package manager.

3) memcache module for drupal installed

what am I doing wrong? thx.

Thank you very much for your answers — I’ve eventually managed with this problem.
Here’s the solution as for openSUSE 11.1.

1. Install memcache extension for php:

   #if apt-get, rpm, or yum doesn't work
   cd /usr/src/
   wget http://pecl.php.net/get/memcache-2.2.5.tgz
   tar -zxvf memcache-2.2.5.tgz
   cd memcache-2.2.5
   phpize5
   ./configure --enable-memcache
   make
   make install
   cp modules/memcache.so /usr/lib/php5/extensions/
   
   # Note: packaged extension modules are now loaded via the .ini files
   # found in the directory /etc/php5/conf.d/
   touch /etc/php5/conf.d/memcache.ini
   echo 'extension=memcache.so' > /etc/php5/conf.d/memcache.ini
   

   now you should restart apache2 service

2. Install memcached daemon for php and run it as a daemon.

3. Install memcache plugin for drupal (all instructions here: http://drupal.org/project/memcache)

UPD. be carefull with upgrading PHP: intalled modules might not be working well with new version — you should recompile them. but somehow “pear install -f pecl/memcache” did the trick for me 🙂
