How build and install Qwt in windows 7?

[ahmed ali]

Hi Everybody,
i am creating an application to read data from file and then plot these data to Gui project, but when i includes <qwt_plot.h> in my project i have some errors
i am using QT 4.7.4 and Win.7 ultimate

errors i have faced are:
C:\Examples\plot_20_3-build-desktop-Qt_4_8_0_for_Desktop_-_MSVC2010__Qt_SDK__Debug\..\plot_20_3\mainwindow.c pp:3: error: C1083: Cannot open include file: 'Qwt_plot.h': No such file or directory


So, can any body help me to fix this errors or how can i build and install qwt lib.?
thanks in advance.

Your question has nothing to do with Windows 7, it is a Visual Studio problem.

If you are using Visual Studio, then you have to include the path to your Qwt\src folder either in your project settings (Properties-> C/C++ -> General -> Additional Include Directories) or as a global setting in Visual Studio Tools -> Options -> Projects and Solutions -> VC++ Directories -> Include files.

And if you are using Visual Studio, download and install the Qt Add-in for Visual Studio so you can convert .pro files into .vcproj files and build things using Visual Studio instead of nmake.
