Hi everyone I'm trying to modify the path to open msp430-gcc

When I use whereis msp430-gcc :

msp430-gcc: /usr/bin/msp430-gcc /usr/bin/X11/msp430-gcc /opt/msp430-47/bin/msp430-gcc

And what I want is that the firs option was /opt/msp430-47/bin/msp430-gcc

In my ~/.bashrc file my path is PATH=~/opt/msp430-47/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

I've tried to cp th msp430-gcc doc to the /usr/bin. It changes me the version but then I can't compile anything because the files are in other dir.. tha is /opt/msp430-47.

How can I make to put all in the correct path ?

  • ~/opt would be a directory called opt in your home directory: if you want the toplevel system directory /opt then omit the ~ – steeldriver Sep 21 '15 at 11:30
  1. Make your preferred path first:


    Check it

    echo $PATH
  2. Fix permissions

    sudo find /opt/msp430-47 -type d -exec chmod +rx "{}" \;
    sudo chmod -R +rx /opt/msp430-47/bin

    PATH=/opt/msp430-47/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games even in /etc/sudoers the secure path is secure_path="/opt/msp430-47/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" – Efrem Blazquez Sep 21 '15 at 11:47
  • @EfremBlazquez, Path setup now ok. Possible you have a permissions problem. Updated my answer – user.dz Sep 21 '15 at 11:51
  • ohhhh I made the Fix permission step... and it works !! Thanks !! can you explain me why if I was working like SU i had problems with permissions.. ??? – Efrem Blazquez Sep 21 '15 at 12:03
  • @EfremBlazquez , With superuser you can read folder/files but you can't execute any command from that bin if they don't have execution bit set. – user.dz Sep 21 '15 at 12:12
