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 9968333456 On Thu, Apr 10, 2014 at 10:53 PM, Yvan Roux <yvan.r...@linaro.org> wrote: > 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).
