Hello! Currently, my gcc (3.3.3) is installed in /usr. I have installed a new gcc (3.4.1) in /usr/local. Now, whenever I do 'gcc --version' the compiler being used is the new one (3.4.1). My questions is this. Which header files (e.g., stdio.h, iostream, etc.) and libraries (e.g., libstdc++, libgcc, etc.) lib will be used by default? Is it the one in /usr/local or the one in /usr? Thanks! ===== Last night as I lay in bed looking at the stars I thought: 'Where the hell is ceiling?' ________________________________________________________________________ Yahoo!
