[Buildroot] Arm build: asm error in libffi?

[Dimitri Kaparis]

Greetings,

I'm doing a build for arm using a crosstool-ng generated toolchain
(gcc 4.4.6, uclibc 0.9.30.3).
With buildroot-2011.05 I'm getting this:


libtool: compile:
(...)/buildroot-2011.05/output/host/usr/bin/arm-unknown-linux-uclibc-gcc

Any ideas?

I guess it's a problem with the toolchain, because here libffi builds
just fine with an ARM CodeSourcery toolchain.

Which binutils version does your toolchain has ?

20.20.1, which is the latest release available through crosstool-ng.

arm-unknown-linux-uclibc-as --version says:
GNU assembler (crosstool-NG 1.12.0) 2.20.1.20100303

Curiously, I was able to complete a build the other day on another
host. I think the only difference was I used uclibc version 0.9.32
instead of 0.9.30.3 for the toolchain. Can this be related?
