Corss-compile for arm

Hi,

I don't fully understand how to cross-compile a Qt program for arm.

I have a debian machine with the IDE (X11/x86) and I need to cross-compile my projets for QtEmbedded (arm) without X or framebuffer - just console projects.
If I undestood correctly I must cross-compile the QtEmbedded before, and then cross-compile my own application with them.

This is my mkspec:

load(qt_config)


Here the ./configure command:

When I launch make I get the following error:

What's bin/moc?

file bin/moc

well, I see it was cross-compiled and of course it cannot be executed on the host machine.
Questions:

- do you see any evidence of mistakes?
- how should I fix the issue?

Thanks in advance
