One of the biggest problem of growing of Linux is the word "compilation".
A "Normal" Windows user ( as I'm ) is almost losing consciousness when seeing this word.

But a practical question. I have a running Apache-PHP.
And now I read:
"To enable InterBase support configure PHP --with-interbase[=DIR], where DIR is the InterBase base install directory, which defaults to /usr/interbase."
Friends, what do I have to do???
Do I have to configure everything from the beginning or there is a way to ADD some option to already configured PHP?
