%general-entities; ]> $LastChangedBy$ $Date$ fftw FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST). &lfs80_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &fftw-md5sum; Download size: &fftw-size; Estimated disk space required: &fftw-buildsize; Estimated build time: &fftw-time; User Notes: Install fftw by running the following commands: ./configure --prefix=/usr --enable-shared --enable-threads && make To test the results, issue: make check. Now, as the root user: make install --enable-shared --disable-static: Use shared libs instead of static libs. --enable-threads: This enables libfftw3_threads.so to be compiled. It is used by e.g. the gimp plugin from G'MIC. Installed Programs Installed Library Installed Directories fftw-wisdom and fftw-wisdom-to-conf libfftw3.so and libfftw3_threads.so None Short Descriptions fftw-wisdom is a utility to generate FFTW wisdom files, which contain saved information about how to optimally compute (Fourier) transforms of various sizes. fftw-wisdom fftw-wisdom-to-conf is a utility to generate C configuration routines from FFTW wisdom files, where the latter contain saved information about how to optimally compute (Fourier) transforms of various sizes. fftw-wisdom-to-conf
