How about using the 'update-alteenatives'?

Another thing is, what happens when an update for one of the compilers is installed. Let's say I have both gcc8 and gcc9 installed. I have gcc9 as my default. What happens when an update for gcc8 is installed? Does it now become the default? Where will /usr/bin/gcc be pointing?

With gcc9, it is like this:

lrwxrwxrwx 1 root root 5 Oct 8 14:11 /usr/bin/gcc -> gcc-9 -rwxr-xr-x 1 root root 760456 Feb 4 22:14 /usr/bin/gcc-9 lrwxrwxrwx 1 root root 8 Oct 8 14:11 /usr/bin/gcc-ar -> gcc-ar-9 -rwxr-xr-x 1 root root 27064 Feb 4 22:14 /usr/bin/gcc-ar-9 lrwxrwxrwx 1 root root 8 Oct 8 14:11 /usr/bin/gcc-nm -> gcc-nm-9 -rwxr-xr-x 1 root root 27056 Feb 4 22:14 /usr/bin/gcc-nm-9 lrwxrwxrwx 1 root root 12 Oct 8 14:11 /usr/bin/gcc-ranlib -> gcc-ranlib-9 -rwxr-xr-x 1 root root 27072 Feb 4 22:14 /usr/bin/gcc-ranlib-9

What happens after gcc8 is updated?

Don't know much about it but maybe it is easier to isolate the extra gcc in a VM? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
