In reply to:
I have a custom install of php, and I keep getting this error when I try the phpize step of installing ffmpeg-php:
Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable is set correctly and then rerun this script.
I've installed autoconf and set the $PHP_AUTOCONF environment variable, but no luck.
I assume you have checked the output of phpinfo() and *confirmed hat your setting of the $PHP_AUTOCONF variable actually *is* being set as you expected/directed?
My only thoughts at this point are that possibly that variable is somehow set incorrectly for your installation (autoconf is not where it is expected) *or* a permission problem that is keeping autoconf from being read.
In addition to the PHP error output, have you checked you server logs for any related/associated error messages? Sometime *they* can shed additional light on the nature of the problem.
Other than those possibilities, I'm not sure what to suggest. Unfortunately, custom PHP installs have a *lot* of potential for "borkage",and it is really hard to tell what might have gone wrong or where the actual problem might lie. I've no doubt that is one of the reasons (among others!) that DH will not support such installations - it would be a huge demand on their support resources.
