This is a peculiar case which affects you if you deploy anything like a lib to a specific folder in Harmattan device. It reports an install error saying
dh_installdeb find: -printf: unknown option dh_installdeb: command returned error code make: *** [binary-arch] Error 1 dpkg-buildpackage: failure: debian/rules binary gave error exit status 2
Bug and solution is clearly mentioned here
This issue is caused because of a broken dh_installdeb script for Harmattan deployment in Mac. Madde dev tools rely on GNU “find” utility which is being eclipsed by Mac’s “find” utility. This causes -printf option not being found which in turn breaks your app deployment.
Replace line 83 in <QtSDK Path>/Madde/madbin/dh_installdeb with
complex_doit("find $tmp/etc -type f | sed s*$tmp** >> $tmp/DEBIAN/conffiles");
