Problem install qwt on windows

[kid17]

what's your develop platform, vs2005 or eclipse?

My develop platform is eclipse.
I have tried to create a folder(x) where I placed all the files .h of src directory of qwt-5.1.1.After I added to my eclipse project in (include path)-Ipath_folder_x and linking library qwt5.dll.
If i try to compile ,i haven't problem but if I run application show a window:
in the title : Microsoft vc++ Runtime library(strange...I don't use vc++)
in the body:This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
