I have compiled the latest GCC 4.7.0, on my Linux Mint 12, using gcc 4.6.1 (default).Compiler compiled successfully, steps followed./configuremakemake installBinaries of gcc-4.7.0 are in /usr/local/bin/ after install step.Now the goal is to make the new compiler the default while also keeping the old one around(no uninstall) i.e. I want to be able to do gcc a.c or g++ a.cpp directly in the terminal window. I have been unable to find a proper series of steps that would help me accomplish this. Also, doing /usr/local/bin/g++ hello-world.cpp generates iostream file/directory not found.Any help is appreciated.
