php - Using ./configure a 2nd time in Linux: Do I need to re-input previous options? -

-

i compiling php , postgresql myself. have got things working fine. there 25 options added (using method http://vladgh.com/blog/install-nginx-and-php-php-fpm-mysql-and-apc) php compile.

if want add option php (e.g. pdo) need re-enter 25 , enter line enabling pg_pdo, or previous options stored , need enter 1 new option? getting @ here ./configure method, not installing postgres. don't understand how ./configure works or if stores it's previous values , can added to.

also, if upgrading postgresql, there need recompile php if not changing options.

i hope clear. have been searching day , can't seem make headway. don't know enough make process linux. running ubuntu 10.04lts server.

yes, need reenter them. ./configure command generate new set of makefile options, overwriting previous one.

luckily, previous ./configure command should still in console's history can press arrow key find it.

assuming shell bash on ubuntu, can ctrlr , start typing ./configure search through command history. keep hitting ctrlr find right one.
