Hello Andreas,

yes I agree.

I didn't looked into libgnutls28-dev:i386 file list because I can't
install it along the amd64 version.

apt-get install libgnutls28-dev:i386

It seems that packages are mutually exclusive. It's a blocker for me.

I don't understand why the -dev package is specific to the architecture.

I'd like to note that I can use Qt 4 to produce both amd64 and i386.
I've installed libqt4-dev and both architecture dependent packages:
libqtcore4:amd64 libqtcore4:i386. And everything is fine to build my
application both for Debian amd64 and i386....

How can we go on with that ?

Michel
