Dear Yvan,

Thanks for your reply.

We are trying to build native gcc compiler for CPU: nViDia Tegra 2 which has ARMv7-a, Cortex-A9 core. We are using host machine as i686 and OS: ubuntu 12.04.

Hi Anwej,

what kind of machine are you building on? my guess is that you try to
do a native build whereas it is a cross one that you need.

Yvan
