There was an error compiling this

[GUJIAN]

Why did I successfully compile my own project and make an error when compiling it? Does the teacher know what the problem is?

@GUJIAN You don't have fftw installed. I have a video on Patreon about installing it on Windows. There are also some instructions on the fftw site - http://fftw.org/install/windows.html

You could also just disable it by removing the pre-processor definition. It isn't needed for this project anyway.

Thank you teacher, but I couldn't find the installation tutorial, fftw3. h, libfftw3-3. dll, libfftw3f-3. dll, libfftw3l-3. dll, libfftw3-3. lib, libfftw3f-3. lib, libfftw3l-3. lib. I don't know where these files are located. Could you please provide a link for your tutorial? Thank you.

The simpler solution is to just remove it from the project, it's not needed. But here's the link to the video on Patreon.

Keep in mind also that FFTW is only suitable for open source projects.

@d-healey Teacher, I installed FFTW3 according to your tutorial, but encountered this issue in the compilation project.

@GUJIAN You need to add the path to fftw3 in the header search paths and extra library search paths of the juicer file.

This is how it looks for me
