Mostly likely, when you compile, the new libraries and headers will get picked up. However, depending on how your LD_LIBRARY_PATH (or ld.so.conf on Linux) is set up, you may not get the right libraries - it will depend on whether /usr/lib is search before /usr/local/lib. I would suspect that /usr/local/lib is searched first, but it just depends on how your system is set up.

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!
