如何在C++上实现fft的问题

我在www.fftw.org上查到一下信息：
Question 3.14. I included your header, but linking still fails.

You're a C++ programmer, aren't you? You have to compile the FFTW library and link it into your program, not just #include . (Yes, this is really a FAQ.)

我想问，我该如何compile the FFTW library and link it into my program？还有就是，我该include fftw3.h还是cfftw3？

你的include没写错，但是fftw.cpp这个文件你也要包括或者导入进你的工程里，然后统一编译
