%description
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.

The library is available as 32-bit and 64-bit.

Group:          Development/Libraries
Requires:       %{name} = %{version}-%{release} pkg-config

%description    devel
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.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "xlc_r" or "gcc -maix64" (or "xlC_r" and "xlf_r",
respectively).
