Screenshots for configuration of FFTW3 in C++ (Windows)

When you download the zip file from “http://fftw.org/install/windows.html”,

By default, the zip file is like this (I use 64-bit version):

First thing you should do is to generate .lib files for these .dll files. Refer to the post here:

(notice in this post also have information for debug in case you find this problem)

Then copy them to the same folder which should looks like:

Copy this folder to your project’s folder (actually you can put it anywhere).

Here begins the screen shots of configuration:

1 Open the property configuration for present project. Choose “General” under “C/C++” option tab.

2 add the .dll file’s directory by click “Additional Include Directories”:

3 under the “Linker/General” option, choose “Additional Library Directories”

4 add the directory of your  .dll file here:

5 add the .lib files’ names under the “Linker/Input” option here:

6 make sure you’ve input all the .lib files you want to use;

Now you should be able to see the external header file under “External Dependencies” :

And include it above the other library:

Done.

In my code, I begin to use it like this:

You should refer to the manual of FFTW3 for the use of it.
