This module requires a C compiler to build. To install, execute the sequence perl Makefile.PL make make test make install Win32 users should use the 'make' program on their system. A ppm package, suitable for Win32 ActivePerl, is available via ppm install http://theoryx5.uwinnipeg.ca/ppmpackages/Math-FFT.ppd for ActivePerl 6xx, or at ppm install http://theoryx5.uwinnipeg.ca/ppms/Math-FFT.ppd for ActivePerl 8xx. If you do not have permission to install modules in the Perl site tree on your system, you can install this in your own library by perl Makefile.PL PREFIX=/home/me/perl \ INSTALLMAN1DIR=/home/me/man/man1 \ INSTALLMAN3DIR=/home/me/man/man3 make make test make install To use modules in this location, either set the PERL5LIB environment variable to include your private module directory, or else put use lib '/home/me/perl/path/to/lib'; at the top of your script.
