To install the FFT library, you will need to have charm++ installed in you system. You can follow the Charm++ manual to do that. Also you will need to have FFTW (version 2.1.5) installed. FFTW can be downloaded from http://www.fftw.org.
The FFT library source is at your-charm-dir/src/libs/ck-libs/fftlib. Before installation of the library, make sure that the path for FFTW library is consistent with your FFTW installation. Then cd to your-charm-dir/tmp, and do 'make fftlib'. To compile a program using the fftlib, pass the '-lfftlib -L(your-fftwlib-dir) -lfftw' flag to charmc.
