RE: Two gcc Installations: conflict in library?

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.

Thanks,

Subject: Two gcc Installations: conflict in library?

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!

Hi Janvier,

When you compile, put in the -v switch.

g++ -v test.cpp

The verbose output will state which header file locations and libraries are 
being used.

HTH,
