Installing Memcache on MAMP

For the better part of 2 hours I tried and failed to get the Memcache extension installed on MAMP.  I tried following several guides, but everything fell flat on it’s face about 75% of the way through.  I eventually figured it out, and I wanted to share it so that other people don’t have to go through the pain and suffering that I did.  It turns out to be surprisingly easy, but YMMV.

Step 1: Install XCode

Step 2: Make the MAMP PHP binary files executable

sudo chmod +xrw /Applications/MAMP/bin/php5.3/bin/p*

Step 3: Get the Memcache extension source

cd ~
wget http://pecl.php.net/get/memcache-2.2.5.tgz
tar -zxvf memcache-2.2.5.tgz
cd memcache-2.2.5

Step 4: PHPize the Memcache extension files

/Applications/MAMP/bin/php5.3/bin/phpize

Step 5: Compile the Memcache extension

./configure
make

Step 6: Add the extension to the PHP.ini file

Add the following to the end of your PHP 5.3 ini file via the MAMP file menu.

extension=memcache.so

Step 7: Copy the memcache extension to the PHP extension folder

cp modules/memcache.so /Applications/MAMP/bin/php5.3/lib/php/extensions/no-debug-non-zts-[yourtimestamp]/

The “[yourtimestamp]” varies per installation, but you should just be able to tab complete that part.

    As an update to Jack’s great tutorial on installing memcache, when I followed his instructions, everything was compiling and configured successfully, but for the life of me, I could not get MAMP to see the module. I had a suspicion that the memcache.so file was compiled for 32-bit or 64-bit and MAMP wasn’t loading the extension correctly.

    if you run into this problem, in Step 5, replace the ./configure line with:

    CFLAGS=’-O3 -fno-common -arch i386 -arch x86_64 -g -Os’ LDFLAGS=’-O3 -arch i386 -arch x86_64′ CXXFLAGS=’-O3 -fno-common -arch i386 -arch x86_64 -g -Os’ ./configure –disable-dependancy-tracking –disable-shared -enable-static

    … Then continue on with the steps and memcache will install against MAMP Pro / PHP 5.3 successfully.

    Thanks for the brilliant tut! I’ve followed it exactly but I get the following error when starting MAMP.

    PHP Warning: PHP Startup: memcache: Unable to initialize module
    Module compiled with module API=20100525
    PHP compiled with module API=20121212
    These options need to match
    in Unknown on line 0

    I am running MAMP Pro v3 with PHP 5.5.10. Any ideas?
