Chris@29: # Add to FFT_DEFINES the relevant options for your desired third-party
Chris@29: # library support.
Chris@29: #
Chris@29: # Available options are
Chris@29: #
Chris@29: #  -DHAVE_IPP         Intel's Integrated Performance Primitives are available
Chris@29: #  -DHAVE_VDSP        Apple's Accelerate framework is available
Chris@29: #  -DHAVE_FFTW3       The FFTW library is available
Chris@29: #  -DHAVE_KISSFFT     The KissFFT library is available
Chris@29: #  -DHAVE_MEDIALIB    The Medialib library (from Sun) is available
Chris@29: #  -DHAVE_OPENMAX     The OpenMAX signal processing library is available
Chris@29: #  -DUSE_BUILTIN_FFT  Compile the built-in FFT code (which is very slow)
Chris@29: #
Chris@29: # You may define more than one of these. If you define
Chris@29: # USE_BUILTIN_FFT, the code will be compiled in but will only be used
Chris@29: # if no other option is available. The default, if no flags are
Chris@29: # supplied, is for the code to refuse to compile.
Chris@29: # 
Chris@29: # Add any relevant -I flags for include paths as well.
Chris@29: #
Chris@29: # Note that you must supply the same flags when including bqfft
Chris@29: # headers later as you are using now when compiling the library. (You
Chris@29: # may find it simplest to just add the bqfft source files to your
Chris@29: # application's build system and not build a bqfft library at all.)
Chris@29:

Chris@29: # alternatives!

Chris@29: 
Chris@29: # Add to ALLOCATOR_DEFINES options relating to aligned malloc.
Chris@29: #
Chris@29: # Available options are
Chris@29: #
Chris@29: #  -DHAVE_POSIX_MEMALIGN     The posix_memalign call is available in sys/mman.h
Chris@29: #  -DLACK_POSIX_MEMALIGN     The posix_memalign call is not available
Chris@29: #
Chris@29: #  -DMALLOC_IS_ALIGNED       The malloc call already returns aligned memory
Chris@29: #  -DMALLOC_IS_NOT_ALIGNED   The malloc call does not return aligned memory
Chris@29: #
Chris@29: #  -DUSE_OWN_ALIGNED_MALLOC  No aligned malloc is available, roll your own
Chris@29: #
Chris@29: #  -DLACK_BAD_ALLOC          The C++ library lacks the std::bad_alloc exception
Chris@29: #
Chris@29: # Here "aligned" is assumed to mean "aligned enough for whatever
Chris@29: # vector stuff the space will be used for" which most likely means
Chris@29: # 16-byte alignment.
Chris@29: #
Chris@29: # The default is to use _aligned_malloc when building with Visual C++,
Chris@29: # system malloc when building on OS/X, and posix_memalign otherwise.
Chris@29: #
Chris@29: # Note that you must supply the same flags when including bqfft
Chris@29: # headers later as you are using now when compiling the library. (You
Chris@29: # may find it simplest to just add the bqfft source files to your
