Plugging GD into PHP, on Leopard 10.5.7

Every Mac web developer will at some time in their lives have to deal with images. Unfortunately, the PHP installation on the Leopard OS (5.2.8 as of OS X 10.5.7) doesn’t have GD compiled in by default. If you’ve tried testing web components like CAPTCHA on your Mac, and can’t render the images, that’s the reason.

First and foremost, I try to make things easy around here. Before you begin the somewhat arduous task of compiling GD (and the pre-reqs) for your Leopard-powered Mac, there is a simpler solution: the Entropy PHP Apache module from Mark Liyanage. I used Mark’s work extensively when on Tiger, and both his compilations and instructions are what I consider the gold standard in simplicity and efficiency. Unless you have XCode tools handy and are really comfortable with the terminal window, I highly recommend going that route instead. When I compiled mcrypt for dynamic loading the Entropy package wasn’t available yet, but it is now and includes mcrypt too.

For those who don’t want an additional PHP install floating around on their machine and/or like everything updated when Apple says so, here’s how you get GD running with PHP on Leopard 10.5.7…


Running a secure web server on your Leopard-powered Mac

This is not something most of you would want to do, but I’m in the midst of a project that requires SSL for testing purposes. My MacBook Pro serves as a primary communications center, research tool, and as the access interface to the blog blather you’re reading right now. Plus, it’s one hell of a development platform too. SSL is a big part of building secure web services, so I’m putting this forth just in case.

Quick note: this is a fairly detailed process, so take a firm hold of the wheel and be prepared for a lengthy ride. You are going to need your terminal and su access. You will be generating encryption keys and certificates, and editing Apache conf files, after the jump.


Plugging mcrypt into PHP, on Leopard 10.5.6

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

The instructions below cater to those folks who a) are developing on OS X Leopard 10.5.6, b) need the capabilities provided by mcrypt during their PHP development, and c) do not want to completely recompile PHP to get there. You’ll get mcrypt loading dynamically for use in PHP with this method.

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… ‘’, 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():

Special thanks go to salty beagle and Kenior Design for giving me the clues to getting the combination of events right.

MORE: Two commenters noted they had their success with the above after updated Xcode to 3.1.2.

Apple PR machine running in overdrive

Leopard gets grand reviews from three major media outlets in one day:

The Wall Street Journal
The New York Times
USA Today

I’m a Mac user, and I’ve been exclusively so for years now. But none of the new features will have me waiting in line for a box of spots, and the thought that I’ll wind up spending at least hundred extra bucks upgrading incompatible software as well (like I did with Tiger) is another deterent.
