Switching

  1. 8. Switching System GCC

    (Optional) Finally, to easy Managing GCC Versions use Alternatives
    So now to Set System for to manage a Multi Compiler.
    First, possibly disable the existing Target with:

    sudo mv /usr/local/bin/gcc /usr/local/bin/gcc.bak

    Then to Add the New GCC with alternatives use:

    sudo alternatives --install /usr/local/bin/gcc gcc /usr/bin/x86_64-redhat-linux-gcc 20

    Again Add the System GCC:

    sudo alternatives --install /usr/local/bin/gcc gcc /usr/bin/gcc 10

    (The Setup is working if as of default /usr/local/bin is preceding /usr/bin on the $PATH Env Var)
    Next to Switch between GCC Versions play:

    sudo alternatives --config gcc

    Last, to test the GCC in use:

    gcc -v

    If not working then you may need to amend the User’s PATH with:

    echo "export PATH=/etc/alternatives:$PATH" >> ~/.bashrc

    And then to Reload it simply run:

    bash
