Are you guys talking about this Packaging error - Command 'dh_make -s -n -p -maemo_test_0.1' failed ? I'm getting it too when trying to deploy an app from Qt Creator to the N900. Would like to know how to get things working.
packagename_version_arch.deb, where "packagename" is the name of the package, "version" is the package version with major, minor, and revision numbers, and "arch" is the architecture for the package. The name of the package itself (not the filename, just the name of the package) can contain lowercase letters, numbers, and the "-" and "+" characters.
