Hi, Is there any way i.e. environment variable or settings file ( .rc ) etc.. which can be used to make gcc search INCLUDE paths/ LIBRARY DIRECTORY paths of my choice by default. ( in addition to the ones it already does like /usr/include for INCLUDES and /usr/lib for LIBRARY DIRS essentially i always use the same -I , -L options for boost, Roguewave etc..is there a way to dispense with this. Thx Digz
