Arm toolchain with gcc / newlib / VFP / hard float - can it be done?

Hi there

I'm trying to build newlib for a baremetal audio project on the Raspberry Pi. It'll spend most of its time doing float-based DSP against deadlines, so I'm eager to get the best floating point performance.

The first question is, does anybody have a build script for building gcc / newlib with vfp / hard float abi? If they do then I'd love to see it so I can stop ineffectually trying to make my broken one work. Otherwise, some advice on mine would be much appreciated. My messy, broken build script is below.

At the moment I'm getting this during the "building newlib" phase:

../../../../../../newlib-2.0.0/newlib/libc/argz/argz_add.c: In function ‘argz_add’:
../../../../../../newlib-2.0.0/newlib/libc/argz/argz_add.c:18:1: sorry, unimplemented: Thumb-1 hard-float VFP ABI

I tried adding --disable-multilib to newlib's configure command in the hope that would stop it trying to build with thumb1, and during the second gcc build I got:

checking for suffix of object files... configure: error: in `/home/joe/building/pi/pixperiments/buildgcc/build-gcc/arm-none-eabi/thumb/libgcc':
configure: error: cannot compute suffix of object files: cannot compile

The contents of build-gcc/arm-none-eabi/libgcc/config.log are below. Nothing in it leaps out at me, but I don't really know what I'm looking for.

Any words of advice, comfort or sympathy would be very welcome. I'm building on ubuntu 12.10.

Thanks,

Joe
