   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?

      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?

   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?

   1. Glen Post authorOctober 10, 2009 at 7:43 pm

      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?

    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?

    I realize this thread is months old but I’m having difficulty getting past the phpize step, and I haven’t been able to find any other resource on the web that helps me solve it. If you have got the time, I am encountering this error:

    jon@memcached-1.0.2: phpize
    Configuring for:
    PHP Api Version: 20090626
    Zend Module Api No: 20090626

    Try `/Developer/usr/bin/gm4 –help’ for more information.
    autom4te-2.63: /Developer/usr/bin/gm4 failed with exit status: 1

    It looks like an error in passing options to the m4 script.. any thoughts?

    This is my version of m4:
    m4 (GNU M4) 1.4.15

       Hey Jon,

       You seem to have a different m4 version installed to me. Mine is:

       This is the version that was installed after using the Xcode installer on my Snow Leopard install DVD. How did you install your UNIX Dev Support tools?

    Ah, I see that the version installed by fink was taking precendence, I hijacked my PATH to use the xcode installed version and the install was successful! Thank you very much.

    Regarding the Memcache vs. Memcached class name that several commenters in this thread have mentioned:

    There are TWO Memcached clients in the PHP Extension Community Library. They are quite unhelpfully named Memcache (http://pecl.php.net/package/memcache) and Memcached (http://pecl.php.net/package/memcached). Here is a handy comparison chart: http://code.google.com/p/memcached/wiki/PHPClientComparison

    The instructions in this blog post are for the Memcached client. If you’re using a library that calls the Memcache class, this client will not work for you. However, the installation steps should be quite similar to get the Memcache client up and running.

    Which is a preferable library? For a long while there was no development activity on Memcache, so it appeared as though Memcached was going to supplant it. However, as of this morning it looks like there is some new activity in the last 30 days on Memcache, so who knows. Some (old) discussion is here: http://serverfault.com/questions/63383/memcache-vs-memcached

    I lost about 15 minutes trying to sort this out, so hopefully some future visitor to this page will save themselves the trouble.

    I realize that this is a very old tutorial, but I am running into an issue that I can’t seem to figure out. I’m running MAMP on my MacBook Pro (10.6.8) and on running the phpize command in memcached-2.1.0 I get the folloiwng error:

    grep: /Applications/MAMP/bin/php/php5.3.6/include/php/main/php.h: No such file or directory
    grep: /Applications/MAMP/bin/php/php5.3.6/include/php/Zend/zend_modules.h: No such file or directory
    grep: /Applications/MAMP/bin/php/php5.3.6/include/php/Zend/zend_extensions.h: No such file or directory
    Configuring for:
    PHP Api Version:
    Zend Module Api No:
    Zend Extension Api No:

    I believe it has to do with MAMP not including the header files, but I don’t know how to fix this. A while back I ran into the same issue when installing the client library for MongoDB, but in that case I got lucky as someone had posted the precompiled mongo.so file. No such luck here, any help would be appreciated…

       Hi Mark,

       Your errors indicate that you are using MAMP, but my instructions are specifically for the native version of Apache that ships with Snow Leopard. Either uninstall MAMP and follow these instructions, or else you will need to install the memcached module via MAMP — this may be helpful:
