Hi there,

I just tried installing FANN by PEAR/PECL, but keep getting an error, which I cannot interprete, since I am not really used to Linux too much, so I hope to get some help here

This is what I did as root:
pecl install channel://pecl.php.net/fann-0.1.1
And this is the feedback:
WARNING: channel "pear.php.net" has updated its protocols, use "channel-update pear.php.net" to update
downloading fann-0.1.1.tgz ...
Starting to download fann-0.1.1.tgz (9,509 bytes)
.....done: 9,509 bytes
3 source files, building
running: phpize
Configuring for:
PHP Api Version: 20020918
Zend Module Api No: 20020429
Zend Extension Api No: 20050606
Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF
environment variable is set correctly and then rerun this script.

ERROR: `phpize' failed
Now basically what I am trying to do is, getting fann to be usable in php... would be thankful for any pointers
