mcrypt?is a file encryption method using secure techniques to exchange data. It is required for some web apps for example? Magento , the shopping cart software or a php framework likeLaravel. This tutorial has been tested in OSX 10.10?Yosemite.

This guide is really for users with the version of PHP that shipped with OSX Yosemite which is version 5.5.14. Other downloadable?AMP stacks already have?mcrypt?baked in.

?

Command Line Tools

First up you will need the OSX 10.10 version of?Command Line Tools?which you can download via the Apple available updates in the App store.

Run in the Terminal

    xcode-select --install
  

?

Getting it on in OS X?Yosemite 10.10

This tutorial works mostly in the?Terminal, launch it from /Applications/Utilities, change directory (cd) to the home account and make a directory that you will work in, call it?mcrypt

    cd ~ ; mkdir mcrypt ; cd mcrypt
  

Get?libmcrypt 2.5.8?from Sourceforge,? ?this is direct download link.

Get the?php?code in a?tar.gz or .bz2?format- ?(version?5.5.14 is the one that currently ships with OSX 10.10)

Move both of these files that you downloaded into your working directory –?mcrypt?in this instance, and go back to Terminal

    cd ~/mcrypt
  

Expand both files via the command line or just double click them in the Finder:

    tar -zxvf libmcrypt-2.5.8.tar.gz
  

    tar -zxvf?php-5.5.9.tar.gz
  

Remove the compressed archives

    rm *.gz
  

Any errors on the command line including C++ and g++ mostly are due to the command line tools missing.

?

Configuring libmcrypt

      cd?libmcrypt-2.5.8
    

    ./configure
  

    make
  

    sudo make install
  

With the libmcrypt configured and libraries now installed, time for to make the mcrypt extension.

?

?

Install Autoconf

Install? autoconf ?– some more Terminal heavy lifting:

    cd ~/mcrypt
  

    curl -O http://ftp.gnu.org/gnu/autoconf/autoconf-latest.tar.gz
  

    tar xvfz autoconf-latest.tar.gz
  

    cd autoconf-2.69/
  

    ./configure
  

    make
  

    sudo make install
  

?

Compile mcrypt php Extension

    cd ../php-5.5.9/ext/mcrypt/
  

    /usr/bin/phpize
  

Output should be similar to:

Configuring for:
PHP Api Version: 20121113
Zend Module Api No: 20121212
Zend Extension Api No: 220121212

    ./configure
  

    make
  

    sudo make install
  

The result of this should be similar to:

Installing shared extensions: ?/usr/lib/php/extensions/no-debug-non-zts-20121212/

?

?

Enabling mcrypt.so ?php Extension

Open?/etc/php.ini?and add the line below at the end

    extension=mcrypt.so
  

If there is no?php.ini?file, ?then you need to make one from php.ini.default?in the same location like so:

    sudo cp /etc/php.ini.default /etc/php.ini
  

And allow write capability

    sudo chmod u+w ?/etc/php.ini
  

Then add the line as above in your favourite text editor:

    sudo nano /etc/php.ini
  

or

    sudo vi /etc/php.ini
  

and add in the line:

    extension=mcrypt.so
  

?

Restart Apache

    sudo apachectl restart
  

That’s it, create a php page with the function?phpinfo();??to see if it loaded correctly.

?

If it didn’t load you may need to declare the extensions directory in /etc/php.ini

    extension_dir = "/usr/lib/php/extensions/no-debug-non-zts-20100525/"
  

?

Hopefully it wasn’t too much of a nightmare…
