The following steps will explain you how to install the mcrypt extension for the default PHP version (5.4.24) that is shipped with OSX Mavericks. You need this extension for stuff like Laravel and phpMyAdmin. Otherwise you will get this error:
Mcrypt PHP extension required.
Step 1: Install autoconf and mcrypt
I used homebrew to install autoconf and mcrypt, which is as easy as:
brew install autoconf mcrypt
If this does not work for you, or you don't want to use homebrew, then check out this tutorial.
Step 2: Build the PHP extension
To build the PHP extension you will need the PHP 5.4.17 source code that is available for download here and extract it:
cd ~/Downloads unzip PHP-5.4.17.zip
Then build the extension using the following commands:
cd php-src-PHP-5.4.17/ext/mcrypt/ /usr/bin/phpize ./configure make sudo make install
Step 3: Enable the extension
All that is left is to enable the extension by editing
/etc/php.ini. If this file is not present, copy
/etc/php.ini.default and rename it:
sudo cp /etc/php.ini.default /etc/php.ini
/etc/php.ini file and add the following:
Step 4: Restart apache
Now just restart apache and you're done!
sudo apachectl restart
