I am using Ubuntu11.04
Then I installed the Qt4.7.2 for X86 and I am using it.

Now, in order to develop a system for ARM, I built a cross tool chain.
I installed gcc-4.5-arm-linux and a set of such gnueabi from Synaptic.
The chain tool works fine.

Then, to use Qt on ARM board, referring to the article below, I install qt-everywhere-opensource-src-4.7.3

. / configure-embedded arm .... So I get errors.
{standard input}: Assembler messages: {standard input}: 1182: Error: selected processor does not support Thumb mode `swp r6, r4, [r3] 'make [1]: *** [.obj/release-shared- emb-arm/qobject.o] Error 1

. / configure-embedded arm-gnueabi .... and I was able to compile.

However, just added a version of the Qt QtEmbedded QtCreator for X86,
a message is displayed "This Qt Version has a unkown toolchain" and I can't chose QtEmbedded.

What is wrong?
Please help me.
