Dear Sir,

Thank you so much for your reply.

I would like to tell you the exact scenario of my end. I have a SBC (nViDia
Tegra 2) which have The Angstrom Linux Distro without GCC compiler.
Currently i have a host PC (i686 and Ubuntu 12.04) on which i  cross
compiles the application for nViDia Tegra 2 and then transfer the
executable to SBC. but now i want to build and compile application on nViDia
Tegra 2 itself. for than I need a native GCC compiler on SBC (nViDia Tegra 2
).

So, Sir please suggest the method to solve my problem.

Thanks in Advance

-br,
Anwej
