That might be possible, but it may not be desirable. It depends on how your compiler is installed, what versions the old and new compiler are, and what OS it's on, among other things. For example if you're upgrading from 2.x to 3.x, then you probably don't want to get rid of your old compiler. The problem is that C++ libraries are not compatible between the two compilers, so if you try to compile a C++ program using your new compiler and use a C++ library built with your old compiler, it's not going to work. It's hard to give a better answer, though, without knowing more about your situation.

Hello, Is it possible when I have compiled a new version of g++ for my system to only use that new version and that I could delete the old version? Thanks, Julian
