I have a problem with pcntl installation. My PHP version is 5.4.4, I followed this tutorial: http://cyberpunx.com/2011/11/pcntl-so-on-osx-lion-and-mamp/
But Pcntl does not load. In php error log I see:
[04-Sep-2012 22:58:16 UTC] PHP Warning: PHP Startup: pcntl: Unable to initialize module Module compiled with module API=20090626 PHP
compiled with module API=20100525 These options need to match
How can I compile pcntl correctly? Thank you for your help!
The most likely scenario is that after the upgrade you forgot to update your php.ini to change the extension_dir.
If you have followed the tutorial to the letter, your extension_dir should be:
/usr/local/lib/php/extensions/no-debug-non-zts-20100525
Also, don't forget to restart Apache after your php.ini changes.
Finally, my solution was completely different. I removed MAMP and activated OSX built-in apache and installed MySQL.
This tutorial helped me a lot: https://apple.stackexchange.com/questions/23751/how-to-turn-mac-os-x-lion-into-a-web-server
Then I followed this: http://cyberpunx.com/2011/11/pcntl-so-on-osx-lion-and-mamp/
...and finally got pcntl working!
//EDIT:
another very easy solution is to download precompiled PHP for mac: http://php-osx.liip.ch/
