How To Install fftw2 on CentOS 8
Introduction
In this tutorial we learn how to install fftw2 on CentOS 8.
What is fftw2
FFTW is a C subroutine library for computing the Discrete Fourier Transform (DFT) in one or more dimensions, of both real and complex data, and of arbitrary input size. We believe that FFTW, which is free software, should become the FFT library of choice for most applications. Our benchmarks, performed on on a variety of platforms, show that FFTW’s performance is typically superior to that of other publicly available FFT software.
We can use yum or dnf to install fftw2 on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install fftw2.
Install fftw2 on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
CentOS Linux 8 - AppStream 43 kB/s | 4.3 kB 00:00
CentOS Linux 8 - BaseOS 65 kB/s | 3.9 kB 00:00
CentOS Linux 8 - ContinuousRelease 43 kB/s | 3.0 kB 00:00

After updating yum database, We can install fftw2 using dnf by running the following command:
sudo dnf -y install fftw2

After updating yum database, We can install fftw2 using yum by running the following command:
sudo yum -y install fftw2
How To Uninstall fftw2 on CentOS 8
To uninstall only the fftw2 package we can use the following command:
sudo dnf remove fftw2
