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

Hi Anwej,
these are the right options for an ARM compiler, but you have to tell gcc that you want to build a compiler on an x86 platform that will be use on an ARM one to produce ARM executable, to do so you have to specify the target triplet of the flags --build, --host and --target, but to build the compiler you will also need to build the binutils, and the libc (and if you build for loinux you need the kernel headers as well). This why kugan suggested to use crosstool-ng (I guess the Linaro wiki page you have seen is about building a native ARM one)

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.

Dear Sir,
Thanks for you page. it is really very helpful to us. We are facing a problem during compiling GCC for our ARMv7-a
Cortex-a9.
We are using following option:
../gcc-linaro*/configure --disable-bootstrap --enable-languages=c,c++ --with-mode=thumb --with-arch=armv7-a --with-tune=cortex-a9 --with-float=hard --with-fpu=vpfv3-d16 --prefix=$home/gcc/gcc-linaro
make -j`getconf _NPROCESSORS_ONLN`
after 2 step we are getting following error:
checking whether putc_unlocked is declared... yes checking whether getrlimit is declared... yes checking whether setrlimit is declared... yes checking whether getrusage is declared... yes checking whether ldgetname is declared... no checking whether times is declared... yes checking whether sigaltstack is declared... yes checking whether madvise is declared... yes checking for struct tms... yes checking for clock_t... yes checking for F_SETLKW... yes checking if mkdir takes one argument... no Unknown CPU given in --with-arch=armv7-a. make[1]: *** [configure-gcc] Error 1 make[1]: Leaving directory `/home/anwej/src/build' make: *** [all] Error 2
Please suggest the solution. where is the problem and what will be
our
next steps.
Thanks in advance.
