meta-toolchain-qte failing on gcc-cross-sdk_4.5.bb for mini6410

[Trevor Hickey]

Hello,

I have been trying to bitbake meta-toolchain-qte for the mini6410 and have
been stuck on this linker problem.

Here is my build configuration.

Build Configuration:
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:

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

Full output is here: http://pastebin.com/bbZtFQkp

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

I've tried adding -mfpu=vfp -mfloat-abi=softfp to the configuration, as
well as --with-float=soft. I have tried everything else I can think of, but
to no avail. I am new to using OpenEmbedded and could really use some help
with this error.

that's an interesting one - I see the same problem here but have no found a
solution yet. It seems that only ARMv6 architectures are affected since all
other I build (ARMv4, ARMv5TE, ARMv7A, MIPSEL, SH4 and some PPC based ones do
not seem to suffer from this).

Greetings

Florian

All those offending objects seems to be generated by calling as
directly.
I think the problem seems to be how your assembler's default is
configured. It seems to me that assembler when called directly generated code for
hardfp calling convention but gcc itself is configured for softfp
calling convention.

can I have a look at one of the offending objects ? say emultls_s.o
secondly can I see at your full build log i.e. log.do_compile.XXXXX
file
