Cross compile fails with 'could not read symbols: File in wrong format'

[jbdean]

Hi,
I've seen this asked and answered, but the answer doesn't work for me.
I'm building on Ubuntu 12.04.5 LTS (GNU/Linux 3.2.0-67-generic-pae i686).
My target is armv7 Cortex-A9.
I'm using:
./configure -embedded arm -xplatform qws/linux-arm-g++
-arch arm
-prefix /usr/local/arm
-platform linux-g++
-little-endian
-armfpa
-no-sm
-fast
-no-qt3support -opensource -confirm-license

my qmake.conf from qws/linux-arm-g++:

qmake configuration for building with arm-linux-gnueabihf-g++

include(../../common/linux.conf)
include(../../common/gcc-base-unix.conf)
include(../../common/g++-unix.conf)
include(../../common/qws.conf)

load(qt_config)

make fails with the 'could not read symbols: File in wrong format'.
I did build first plain vanilla to ensure everything worked.
Nothing I"ve found works....

Thank you,

The problem was the gcc/g++ in /usr/bin were both arm target.
So LD did not understand.
