Please try my hack based on Linaro crosstool-ng Canadian windows build.
1) wget http://cbuild.validation.linaro.org/snapshots/crosstool-ng-linaro-1.13.1-4.8... 2) tar -xf crosstool-ng-linaro-1.13.1-4.8-2014.02.tar.bz2 3) cd crosstool-ng-linaro-1.13.1-4.8-2014.02 4) sed -i 's/i586-mingw32msvc/arm-linux-gnueabihf/g' contrib/linaro/build.mk 5) sed -i 's/libiconv//g' steps.mk (libiconv is only for Windows) 6) make -f contrib/linaro/build.mk
Finally you will get a toolchain at
./builds/arm-linux-gnueabi-win32/install
(Please ignore the fails at the end to package windows staffs. )
Good luck! -Zhenqiang

Dear Chen,
Thanks for your reply.
Yes, I am cross compiling gcc for ARM native GCC compiler. I will follow the canadian build and i am also going to try linao crosstool-ng for the same.
Please suggest the steps for same.
Thanks in Advance

Dear Yvan,
I am going to adopt crosstool-ng option. I will update you the status soon. Thank you so much for you support. Let me try first.

It seams to me you want a "cross-native" build. The process is similar with "canadian" build. If you want to try linaro crosstool-ng, I will give you some instructions.

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)
Rgds, Yvan
