Plugging mcrypt into PHP, on Leopard 10.5.6

mcrypt on Fedora Core easy - on Leopard with PHP 5.2.6 not so much.

First, you are going to need a few things…

1) libmcrypt-2.5.8, which you can pick up here;

2) PHP 5.2.6 source, which you grab here; and

3) Xcode 3 tools (dig through your sock drawer to find your Leopard disk).

Next, create a directory at root called ‘SourceCache’ and dump the files from #1 and #2 in there and unwrap.

Move to the libmcrypt-2.5.8 directory, and punch in this…

MACOSX_DEPLOYMENT_TARGET=10.5 CFLAGS='-O3 -fno-common -arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' LDFLAGS='-O3 -arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' CXXFLAGS='-O3 -fno-common -arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' ./configure --disable-dependency-tracking

and then…

make -j6

and finally…

sudo make install

libmcrypt is ready - now for the PHP extension…

Move back to /SourceCache, then down to php-5.2.6/ext/mcrypt - type…

/usr/bin/phpize (phpize should be in /usr/bin - if not go find it and change the command as appropriate)

Then configure as follows…

MACOSX_DEPLOYMENT_TARGET=10.5 CFLAGS='-O3 -fno-common -arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' LDFLAGS='-O3 -arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' CXXFLAGS='-O3 -fno-common -arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' ./configure --with-php-config=/Developer/SDKs/MacOSX10.5.sdk/usr/bin/php-config

Again make -j6 then sudo make install

Make sure you have php.ini in the /etc directory (it may be php.ini.default to start, so rename it). Ensure that enable_dl = On but do not remove the ; from in front of ;extension_dir = "./". UPDATE: Almost forgot - add one line to the .ini file in the Dynamic Extensions section… ‘extension=mcrypt.so’, without the quotes of course (thanks to Badrul).

Restart Apache - when all’s said and done you should be able to see this with phpinfo():
