This is because you have both versions installed, with 4.6 being treated as the default one.

You can explicitly choose which one to use.

$ gcc-4.7 --version

gcc-4.7 (Ubuntu/Linaro 4.7.2-22ubuntu4) 4.7.2

[...]



$ gcc-4.6 --version

gcc-4.6 (Ubuntu/Linaro 4.6.3-15ubuntu3) 4.6.3

[...]

The easiest way make gcc-4.7 the default gcc is to move the symlink of /usr/bin/gcc:

sudo rm /usr/bin/gcc

sudo ln -s /usr/bin/gcc-4.7 /usr/bin/gcc
