Building additional PHP modules on OSX

Normally I try to avoid dealing with PHP if at all possible, but there is now a PHP port of py-amqplib called php-amqplib, and I offered to help out with it a bit. Maybe partially out of guilt for having written the mess of Python code it was based on :)

I thought it would be handy to work on it using my MacBook. OS X 10.5 (Leopard) has PHP 5.2.6 built in standard, but unfortunately it doesn't have the bcmath extension included, which php-amqplib makes use of. Turns out building the module wasn't that difficult. This page got me going - although building bcmath was much simpler. Since I had the Apple Developer Tools for 10.5 installed, it was just a matter of ...

• mkdir /SourceCache
• cd /SourceCache
• fetch https://www.php.net/get/php-5.2.6.tar.gz/from/this/mirror
• tar xzvf php-5.2.6.tar.gz
• cd php-5.2.6/ext/bcmath
• phpize
• ./configure
• make
• sudo make install
• cd /etc
• cp php.ini.default php.ini

And then edit /etc/php.ini to make these two changes:

--- php.ini.default     2008-07-15 14:19:15.000000000 -0500
+++ php.ini     2008-12-08 21:44:52.000000000 -0600

After that, I was able to run the amqp_test.php file for the first time, sending a message and receiving it in py-amqplib's demo/demo_receive.py
