Compilation of a library (FFTW)

[Zool]

I started use and installation of external libraries, but as part of a project, I need to use FFTW. I downloaded the archive containing the library, but I did not find any file. A, so that I can not include it in my Qt project. Apparently there is no makefile, but I have files Makefile.am and Makefile.in in my file.

FFTW++ can also exploit the high-performance Array class, FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data.

C: \ Qt \ (sub-folder of your version of Qt, usually something like 2009.01) \ bin \ qtenv.bat .

If you come home that Qt 4.5 (the second file is to replace eh you put that you have in C: \ Qt). And after you do what you want to do (without the. /)

To perform FFTs efficiently on the Altix, the above vendor libraries generally offer the best performance and scalability. FFTW will compute the DFT in both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST).
