Re: How can I install gcc in different partition?

The current linux os I'm using is in /dev/sda7, mounted as /(root).
I've mounted /dev/sda2 in /media/sda2. Now trying to install gcc in
/media/sda2/usr/bin.

How can a compiler make code? How can a cross compile make code? I
knew, compilers compiles code and generate object code.
