PHP 5.3.0 on Mac OS 10.6 (Snow Leopard)

Recently, I started to use PHP 5.3.0 extensively, thanks to the move of Symfony 2 to PHP 5.3. To do my work, I need to have several different versions of PHP at hand, with different configurations, and so I always compile my own PHP and Apache binaries on my Mac. But as Snow Leopard comes bundled with PHP 5.3.0, I started some PHP 5.3.0 experiments with the bundle version and everything went well for a couple of days.

Now that I use PHP 5.3.0 more and more, I decided it was time to compile my own version. As it turns out, compiling PHP 5.3.0 on Snow Leopard is a bit involving. As I loose some time before finding the right solution, here is what I did step by step (I have just followed the tips referenced in the ticket opened for the issue on php.net, so all credits go to them).

First, I ran the configure script with my usual options and added --with-iconv-dir=/usr at the end:

$ ./configure ... --with-iconv-dir=/usr

I then patched the iconv.c file the same way Apple did for their own version:

To apply the patch, save the above text in a file (patch) and from the root source of PHP, type the following command:

$ patch -p1 < patch

Then, add -lresolv to the EXTRA_LIBS variable:

$ export EXTRA_LIBS=-lresolv 

Eventually, run the usual make commands

$ make
$ make install
