The current 6.0 version has a minor bug in a build-system when building on Mac. By default, qwt is built in debug mode resulting in a Framework called qwt_debug. However, all dependent parts of Qwt and the examples link against the release lib. Changing the configuration to release works.
This should probably be fixed at some time in the respective pro files so that building in debug mode works as well (from the start without hacking pro files, that is :-)
Bye,
Andreas
