Hi Felipe,
This is really nice to have good guidance from your side. I will
explain you about my system side.
I have Fedora 11 installed on my system. GCC version is 4.4.1. To install
sbox2 i am following commands as followed.
I have downloaded sbox2-2.0 and qemu-0.11.0.tar.gz.
Both are resident in the following directory
/tmp/sbox2/sbox2-2.0
from here i have given following commands
./autogen.sh
make install prefix=/opt/sb2/
But my make fail and i have applied following patch and get success for
installing sbox2-2.0

After that i have installed qemu by giving following commands.
./configure --prefix=/opt/qemu/ --target-list=arm-linux-user
make install
i have added sb3 bin path to my PATH variable.
My cross tool chain is installed at following path which is from
Codesourcery( Sourcery G++ Lite version) and
is installed at /opt/arm-2008q3/.
These are my system set up.
Now when i give following command to set up qemu for my cross tool chain it
gives following error.

Why did you add the '--host' option? It's nowhere on any instructions.
Read this carefully: scratchbox was created to forget about
cross-compilation; you don't need to specify the host, target, or
anything.

Of course it's failing because it thinks it's cross-compiling, so it's
not using scratchbox.
> checking whether we are cross compiling... yes
This question has nothing to do with GStreamer, you should ask it in
the scratchbox mailing list.
Cheers.
