******SONASOUND********* FFTW ****************
SonaSound works best with DOUBLE precision FFTW!
Beginning with version 1.1 SonaSound works with FFTW3 as well. All versions before that only use FFTW2.
The configure scripts honours any symlinks called librfftw.so, libfftw.so, fftw.h and rfftw.h and uses them first. So this is a way to force it to use a certain precision.
Instructions to get fftw running
- Did you use the same compiler-version for fftw and SonaSound? If not, Do so!
- Did you compile fftw with --enable-float ?
If so, and you didn't sepcify --enable-type-prefix try recompiling without --enable-float or with --enable-type-prefix!
- Did you compile with --enable-shared and over-optimized the code?
Try to build the static libraries, only. or switch off -fexpensive-optimizations in $CFLAGS
- What Does config.log say?
Maybe something about unresolved symbols? Recompile fftw with above features and with the same compiler you're trying to use now.
- Recommended configure options are:
--enable-type-prefix --enable-threads for the not-so-faint-hearted: --enable-vec-recurse on Intel-compatible: --enable-i386-hacks
If you're absolutely sure, your fftw is correctly installed and working and configure still fails, try symlinking your library of choice (libdfftw.so or libsrfftw.so, or whatever it is called) to libfftw.so and rerun ldconfig and configure.
