Building gcc using OpenEmbedded problems

Building gcc using OpenEmbedded problems

[Trevor Hickey]

Hello,

I am using OpenEmbedded to build a toolchain for an embedded system
and am running into trouble when it comes to building gcc.

Bitbake/OpenEmbedded config:
BB_VERSION        = "1.10.2"
METADATA_BRANCH   = "master"
METADATA_REVISION = "8e7ed36"
TARGET_ARCH       = "arm"
TARGET_OS         = "linux-gnueabi"
MACHINE           = "mini6410"
DISTRO            = "angstrom"
DISTRO_VERSION    = "v2012.01"
TARGET_FPU        = "hard"

I followed the instructions on
http://www.openembedded.org/wiki/Getting_started to set up my
OpenEmbedded environment.

Here is the error output:

/home/balute/tmp/sysroots/i686-linux/usr/armv6/arm-angstrom-linux-gnueabi/bin/ld:

The "VFP register arguments" and "failed to merge target" errors occur
repeatedly.

I have been unsuccessful trying to solve this problem so far, so if
anyone knows what could be causing it, any help would be appreciated.
I'm sorry if this is not the place to be asking this, but it looks
like a gcc compilation issue rather than an OpenEmbedded/Bitbake
issue.
