When done, edit/create /etc/php.ini and add:

next issue:
sudo apachectl graceful

OS: Snow Leopard Server 10.6.4
PHP (Came /w OSX): 5.3.2

I downloaded libmcrypt (libmcrypt-2.5.8.tar.gz) and installed per the instructions above. I downloaded the source for PHP 5.3.2 (php-5.3.2.tar.gz); however, it was missing the “mhash” directory. So I downloaded mhash (mhash-0.9.9.9.tar.gz) and put it in the php source folder. This was missing “config.m4″, so, I copied it over from the “php.5.2.13.tar.gz” and put it in. That resolved the phpize problem.

Now, I am receiving the following error when trying to ./ configure mhash and do not know where to go from here:
configure: error: Please reinstall libmhash – I cannot find mhash.h

After reading the thread, I tried installing using “php.5.2.13.tar.gz”. I still end up at the “configure: error: Please reinstall libmhash – I cannot find mhash.h” error when trying to ./configure mhash.

Again, I sincerely appreciate any help anyone can provide.

Thank you!

thanks a lot for this walk through; saved me an awful lot of time!

a few notes you might want to add for clarity:

- the source which needs to be downloaded is php-5.2.13 (and not php-5.3.2 which is on top of the download page)
http://nl3.php.net/get/php-5.2.13.tar.bz2/from/a/mirror

- the mhash extension is not present in the php-5.3.2 source. even though the install from the 5.2.13 source results in a “configure: error: Please reinstall libmhash – I cannot find mhash.h” message, mcrypt installed and works without any issues… looks like mcrypt does not require the mhash extension to be installed

- as ploughguy already pointed out; the mcrypt extension needs to be activated. simply add: extension=mcrypt.so
to your php.ini file, restart apache and mcrypt is activated / shows up in the phpinfo view (modes_dir & algorithms_dir both use the default path so no need to uncomment those lines)

How did you fix your last issue?
I was also missing mhash from the PHP Source, I did have hash though. I downloaded mhash from here..
http://mhash.sourceforge.net/
I am having the same issue as you when running phpize for mhash.
I get this error
Cannot find config.m4.
Make sure that you run ‘/usr/bin/phpize’ in the top level source directory of the module

I am stuck. How do I proceed?
Thank you
