My scratchbox is the normal one.

For qt:
As "usual" I patched it with the debian patch first, as it's supposed to be for a kindof debian target system.

http://packages.debian.org/lenny/libqt4-core
Don't know if you know debian pages,
On this page, you have the upstream and the debian patch
http://ftp.de.debian.org/debian/pool....1.orig.tar.gz
http://ftp.de.debian.org/debian/pool....3.1-2.diff.gz
It even shows that it compiles on arm, armel is unfortunatly not yet part of the debian system, thought it has been asked months ago.
Under x86 target (oops I hope that I didn't make a bad assumption from the start of this thread, that you are talking about the same target!)
Then I wanted to still compile it the debian way
debian/rules binary

But it needed some newer "quilt" tool for putting into cdbs and I was not able (and lazy) to correct the problem.

So I did the normal
./configure
make
then it failed on precompiled headers so
./configure -no-pch
make
1.3G later, it was compiled.

I'm new to this scratchbox but I'm a bit surprised that you get a qemu error during compilation. I would expect it during runtime maybe. So it must be gcc-arm that creates this or?

Are you able to locate the exact file that creates this problem?

If all you did for my tablet and for others, I'll be happy to help you. Unfortunatly I can't give you access to my box because I have no internet at home.

Bye
