Use this: http://johnhforrest.com/2010/09/inst...wt-on-windows/
Use his qwtconfig.pri, only change destination
Use Qt Creator -> run qmake, rebuild qwt.pro
Use Qt Command from Start->All Programs menu, use qmake, mingw32-make

Copy libqwtd.a "from C:\Qt\2010.05\qt\qwt-6.0.0-rc5\lib to C:\Qt\2010.05\qt\lib"

all examples are working well but with a lot of errors during building project
