fftw imported in debian science ( Paul Brossier didn't do a single upload since two years

fftw3 for DEBIAN
Some of the changes made for version 3 of FFTW necessitated changes to the API,
so you will need to make (minor) changes when moving existing programs to this
version. See the documentation (in package fftw3-doc) for details.
In fftw2 separate packages included optimizations for SIMD
instructions. In fftw3 all such optimizations (x86 and powerpc) are
included in the regular libraries. The routines should automatically
detect the capabilities of your processor. Also, the package contains
three different precision versions (single and double as before, plus
a new long double version).
The -dev version of a package contains the headers and a statically
linked copy of the libraries. You need to install this if you intend
to compile a program which uses fftw. Be careful when compiling
against the static libs as the library linker (ld) looks for shared
libraries first. Some people prefer to use static libraries as there
can be a speed advantage (3-30%) on register starved architectures
(like x86 machines).
The package also contains a threaded version of fftw.
Using the threaded version is almost identical to using the non-
threaded version, but the function calls are renamed and you
need to call a special function first to handle some housekeeping.
See the documentation for details.
Unlike fftw2, there are no MPI based libraries at this time. Upstream
should release them soon. Once upstream adds MPI support, the Debian
package will include it.
To top it all off, you can call fftw from fortran. See the docs at
(needs package fftw-doc installed).
Checking the fftw library for correctness
A 'make check' is run during the Debian build. This runs a number of tests
on the library but does not test all aspects of fftw.
Some users may want to run more complete checks on the library.
Unfortunately, it is difficult to compile or run the checks outside
the source so a precompiled binary is not included with the package.
To enable users to check the library for correctness, the
instructions for compiling the source are included here:
apt-get source fftw3 (you need a deb-src line in /etc/apt/sources.list)
cd fftw3-3.0
Run the configure line from debian/rules appropriate for your architecture and
the precision you would like to test. For example, to run the double precision
tests on an x86 machine you would run:
./configure --prefix=/usr --enable-shared --enable-threads --enable-sse2
Then compile the source and go into the tests directory:
cd tests
You are now ready to run the tests. You can run individual tests yourself or
you can run the automated tests. For details on running tests yourself, read
the README file. There are three choices for the automated tests:
make check (takes a few minutes)
make bigcheck (takes hours to run)
make paranoid-check (you tell me how long it takes)

This package uses quilt to manage all modifications to the upstream
source. Changes are stored in the source package as diffs in
debian/patches and applied during the build.
Read more about this on /usr/share/doc/quilt/README.source.

Description: library for computing Fast Fourier Transforms
The FFTW library computes Fast Fourier Transforms (FFT) in one or more
dimensions. It is extremely fast. This package contains the shared library
versions of the fftw libraries in single, double and long double precisions.
Note that on some architectures double is the same as long double in which
case there is no long double library.
To get the static library and the header files, you need to install
libfftw3-dev. For documentation, see libfftw3-doc.
