   Glen,
   Thank’s again for this excellent tutorial. 2 issues here for me:
   I first followed the tutorial but couldn’t get memcached to work on SL 10.6.
   Then i realized that i had to specify has for “mcrypt” to compill for 64 bit so i started the whole process by typing in terminal:
   export CFLAGS=”-arch x86_64″
   Everything installed fine and i added to php.ini:
   extension=memcached.so

   2nd (minor) issue: for the php extension, this line is missspelled:

   cd memcache-1.0.0; phpize –> # cd memcached-1.0.0; phpize

   Thank’s again

   Thanks for the feedback, I’ve corrected the path to the memcached PHP extension directory. I personally didn’t need the CFLAGS environment variable set, but if you have problems then it makes sense to include it to specifically build 64 bit libraries.

   Just curious as to why you choose to use /temp to hold all the files?
4. Glen says:

   Actually, it’s not particularly important where you have your source files. I picked /tmp because I wouldn’t need the sources after install. The system cleans /tmp periodically so it’s a handy way to save space. If you think you might need the source code again in the future, it would make more sense to save to, for example, ~/src or perhaps /usr/local/src if you want to make it available system-wide.

   Thanks, that is what I figured. This is my first time through compiling my own php extensions — I had been using entropy previously. One more question. I notice you did not ure the –prefix flag. Do you have any strategies for keeping /usr/local organized?

   Okay, I followed your steps without any problems, but here’s the weird thing:
   Fatal error: Class ‘Memcache’ not found in
   That’s what I get when I’m trying to use the memcached module in PHP..
   BUT, when I create a phpinfo()-file:
   memcached
   memcached support enabled
   Version 1.0.0
   libmemcached version 0.31
   Session support yes
   igbinary support no
   Doesn’t make sense imho. Who knows what’s going on here?
7. Glen says:

   Martijn: can you post the code that is causing the error?
8. Rodrigo Dominguez says:

   Yes, I’m having the same issue
   I installed memcached, I got it listed with phpinfo, but if I do something like
   $a = new Memcache();
   it brokes saying that it cannot find the class

   I’m having the same problem of The Memcache class not being found. Has anyone found a solution for this?
10. Glen says:

    The class name is actually Memcached, so you would create a new instance using the following:

    m1 = new Memcached();

    For full information about the class, please see http://php.net/manual/en/class.memcached.php

    Hi there, I did have this kind of error and I also did php -i | grep memcache and it says memcache is enabled, but my solution that solved the problem was when I edited the php.ini, i simply modified the extension_dir=”./” line to the full path of the extensions directory which now looked like this, extension_dir=”/usr/local/lib” — you need to check where the extension directory of the php reside and make sure memcache.so is there..

    then i simply restarted httpd and alas the problem is gone.

    you can check the detailed steps here:

    I actually don’t get it : which class should it be ? Memcache or Memcached

    I installed everything as stated, got memcached support => enabled
    libmemcached version => 0.31

    but in the lextensions library, I have a module memcached.so testing
    $memcache = new Memcached;
    $memcache->connect(’localhost’, 11211) or die (”Could not connect”);
    I get :
    Fatal error: Call to undefined method Memcached::connect()
    it seems that the class should be Memcached.., but connect is wrong !
    so I tested
    $memcache = new Memcached;
    $memcache->addServer(’localhost’, 11211) or die (”Could not connect”);
    and got the connection
    but an error later in the number of parameters :
    $memcache->set(’key’, $tmp_object, false, 10) or die (”Failed to save data at the server”);
    Warning: Memcached::set() expects at most 3 parameters, 4 given

    I am not a php dev… so what’s wrong there ? why some teste examples use Memcache and other Memcached (any change between php versions ?…)

    thanks for php enlightments )

    I tried this on 10.6.2 Server, and I got through the process ok, but memcached doesn’t show up in the phpinfo() page. Is there anything different I should be doing?
15. Art says:

    December 8, 2009 at 5:58 am

    Got it figured out. Needed a specific directive with the full path as Xifer84 suggested. Thanks!

    I received the successful install message -

    “mike-2:memcached-1.0.2 mike$ sudo make install
    Installing shared extensions: /usr/lib/php/extensions/no-debug-non-zts-20090626/”

    - and restarted apache, but I don’t see the memcache section within a file containing phpinfo(). I’m running SL 10.6.4 – any thoughts?

    I have a problem when I get to the stage of installing the PHP extension. When running pecl download memcached I get the following error:

    Warning: touch(): Unable to create file /usr/lib/php/.lock because Permission denied in PEAR/Registry.php on line 835

    I checked the folder, and despite being administration of my iMac (running Snow Leopard), the folder says I can only read in the “Get Info” dialog, and I’ve been unable to change the owner to myself via sudo.

    What can I do to install memcached at this stage?

    Ignore my last comment; I’m now at the same point as Mike (comment xvii). Any thoughts?
