hey jpn,
it doesnt work sadly.. neither in debug or release mode. and the debug mode doesnt give any usefull information either. i guess my .pro file isnt set up right. i dont really know how to link qwt properly.

Is noone using eclipse and qwt under windows? i would be really happy about a step-by-step installation guide cause the qwt lib would really save me a lot of work! or is there maybe a precompiled win-qwt-package?
