With that configure line, you need to build the gmp, mpc, and mpfr for ARM. That configure line says that you want to build a compiler which will run on an ARM system, and that you want to do the build on a x86 system. You will have to copy the resulting compiler from the x86 system to the ARM system before you can run it. Ian
