- (Like in the Leopard tutorial, I assume you have installed the Xcode & related developer utilities and that all downloads are saved in the "Downloads" folder in your home). Visit the libpng, libjpeg and PCRE homepages and download the latest release available for both. As of writing, the most recent releases are libjpeg 7, libpng 1.2.39 and PCRE 7.9.
- Compile libpng and libjpeg statically:
cd ~/Downloads && tar xfz libpng-1.2.39.tar.gz
cd libpng-1.2.39
./configure --disable-shared --enable-static
make && make install DESTDIR=`pwd`/localinstallcd ~/Downloads && tar xfz jpegsrc.v7.tar.gz
cd jpeg-7
./configure --disable-shared --enable-static
make && make install DESTDIR=`pwd`/localinstallcd ~/Downloads && tar xfj pcre-7.9.tar.bz2
cd pcre-7.9
./configure --disable-shared --enable-static
make && make install DESTDIR=`pwd`/localinstall - Since PHP will be built with MySQL support, download and install MySQL x86_64 for OS X. As of writing, the latest version is 5.1.38.
- Download PHP 5.2.10, available here
- Next, PHP needs to be prepared for compilation. As detailed in PHP bug #49267, a small change is required to get PHP to compile on Snow Leopard:
- Type in the terminal:
cd ~/Downloads && tar xfj php-5.2.10.tar.bz2
cd php-5.2.10
nano ext/iconv/iconv.c - Skip down to line 185 (Tip:
shows current line) - Remove the
libon#define iconv libiconvso that the code reads like this:#ifdef HAVE_LIBICONV
#define iconv iconv
#endif - Hit
and to save the file - Hit
to quit nano
- Type in the terminal:
- Now, PHP is ready for compilation. We will use a configure command relatively similar to the command extracted from phpinfo() earlier:
./configure '--prefix=/usr' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--disable-dependency-tracking' '--sysconfdir=/private/etc' '--with-apxs2=/usr/sbin/apxs' '--enable-cli' '--with-config-file-path=/etc' '--with-libxml-dir=/usr' '--with-openssl=/usr' '--with-kerberos=/usr' '--with-zlib=/usr' '--enable-bcmath' '--with-bz2=/usr' '--enable-calendar' '--with-curl=/usr' '--enable-exif' '--enable-ftp' '--with-gd' '--with-jpeg-dir=/Users/shortname/Downloads/jpeg-7/localinstall/usr/local' '--with-png-dir=/Users/shortname/Downloads/libpng-1.2.39/localinstall/usr/local' '--enable-gd-native-ttf' '--with-ldap=/usr' '--with-ldap-sasl=/usr' '--enable-mbstring' '--enable-mbregex' '--with-mysql=/usr/local/mysql/' '--with-mysqli=/usr/local/mysql/bin/mysql_config' '--with-mysql-sock=/tmp/mysql.sock' '--with-iodbc=/usr' '--enable-shmop' '--with-snmp=/usr' '--enable-soap' '--enable-sockets' '--enable-sysvmsg' '--enable-sysvsem' '--enable-sysvshm' '--with-xmlrpc' '--with-xsl=/usr' '--with-pcre-regex=/Users/shortname/Downloads/pcre-7.9/localinstall/usr/local'EXTRA_CFLAGS="-lresolv" make -j2Remember to replace shortname in /Users/shortname to your system account's shortname. If you're not sure what that is, type
whoamiin a terminal to find out. - Finally, backup Snow Leopard's PHP extension so that PHP 5.3 can be restored later, and copy the PHP 5.2.10 extension in its place:
sudo mv /usr/libexec/apache2/libphp5.so /usr/libexec/apache2/libphp5.so.orig106
sudo cp libs/libphp5.so /usr/libexec/apache2/libphp5.so - The final step is to restart Apache - this can be done by toggling Web Sharing in System Preferences, or alternatively via the apachectl command:
sudo apachectl restart - This error occurs if

Since my update to Snow Leopard, I was pleasantly surprised to find that Apple has updated PHP to version 5.3 and also included the GD extension. While I no longer have to rebuild the extension manually like on Leopard, these changes to PHP brought around a different problem: Drupal is currently not compatible with PHP 5.3 (#360605).
I've been trying to get my local Drupal installations working, and although the patch from post #84 works pretty well (when applied to a D6 CVS checkout), Ubercart is still nonfunctional. Since I am currently building and testing Ubercart-enabled sites, my only remaining option was to downgrade to PHP 5.2.10. I wanted to have the same extensions and options that Apple's PHP 5.3 build had, so I started by viewing the output of phpinfo() and copying the configure command. To compile PHP, locally installed copies of libpng, libjpeg and pcre are required so let's started with that:
That's all! Now run phpinfo() and verify that PHP 5.2.10 is up & running. While I was trying to get this working, I stumbled accross two compile errors - for the sake of completeness, I've listed them below along with the failure cause:
