Re: FC4, FC6, F7 what works, and don't

One exception is a library that does the Fast
Fourie Transorm on an input signal. It was available by yum on FC6 and
F7 but when I tried to ./configure it would not find fftw. I had to get the tar ball and compile it and install on /usr/local/

Don't know about FC6, but its available just fine for F7 (see below) - No need for the tarfile approach, although I guess it worked for you ...

Notes

1. fftw and fftw2 are different -  don't know which you need.
The Boys/Girls at MIT found the version 1.x was so popular they started a version 2.x which alas no-one uses. It will not work with gmfsk.
2. Did you install the associated -devel package as well as the main library package.
Nope my error!
You need the -devel package in order to get the header files need to build other packages against it I.e. development).

Chris

Yes I should have asked for fftw.devel and that would get both. Next time...

fftw-devel
Headers, libraries and docs for the FFTW library
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.

This package contains header files and development libraries needed to
develop programs using the FFTW fast Fourier transform library.

Headers, libraries and docs for the FFTW library
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.
