How do I do I run gcc-49 with just 'gcc' on OSX?

Question

I recently installed gcc 4.9, with a previous version of gcc that was installed by default before.

When I type gcc, the previous version of gcc runs. How could I make my newly installed gcc 4.9 run when I type gcc?

Answer 1

You should do this:

cd /usr/bin
mv gcc gcc-old
ln -s gcc-4.9 gcc

Or you should have a look to gcc_select
