I used http://wiki.forum.nokia.com/index.ph..._quick_project instead and it worked with the example. When I moved my code to the src folder and I add my sourceses, headers, qt libs and CONFIG += mobility and MOBILITY += sensors, and then try to run dpkg-buildpackage it gives me the following error:
failure: no dependency information found for /sysroots/fremantle-arm-sysroot-1014-slim/usr/lib/libQtsensors.so.1 ( used by debian/qexercise/usr/bin/qexercise)
dh_shlibdeps: command returned error code 512

what is the problem? :S
