Hey Guys I'm trying to install xcache on our web server (php optcode cacher) but I am having the following error. I have download the xcache tar ball, unzipped and when in the unzipped directory attempting to run phpize but it fails with the following error: [root at server1882 xcache-1.2.2]# phpize Configuring for: PHP Api Version: 20041225 Zend Module Api No: 20060613 Zend Extension Api No: 220060519 Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable is set correctly and then rerun this script. Ok, $PHP_AUTOCONF doesn't exist so I made it in my bash profile and set to it /usr/local/bin where autoconf is installed too. After logging in and out it didn't work although the environment variable had correct exported. I checked online some people have mentioned you need libtool installed aswell but I have that too (and automake before you ask, all three are installed and have symbolic links in /usr/bin to /usr/local/bin) but this still isn't working and I can't work it out. Can anyone shed any light on this for me? Thanks for reading listee's!
