I've installed an apache2.0 server on my linux system (it works fine) and tried to install php 4.3.4 enabling apache and mysql, when running configure however I got the following error:
./configure: line 2425: lex: command not found
configure: error: cannot find output from lex; giving up
since I'm sort of new to linux I don't know what to do about it...
I was using these installation instructions: http://www.php.net/manual/en/install.apache2.php
Does anyone have any idea what it means and/or how to fix it?
Any help will be greatly appreciated.
