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
