This .zip archive contains DLL libraries and the associated header (.h)
|
|
and module-definition (.def) files of FFTW compiled for Win32. It
|
|
also contains the corresponding bench.exe test/benchmark programs
|
|
and wisdom utilities.
|
|
|
|
There are three libraries: single precision (float), double precision,
|
|
and extended precision (long double). To use the third library,
|
|
your compiler must have sizeof(long double) == 12.
|
|
|
|
In order to link to these .dll files from Visual C++, you need to
|
|
create .lib "import libraries" for them, and can do so with the "lib"
|
|
command that comes with VC++. In particular, run:
|
|
lib /def:libfftw3f-3.def
|
|
lib /def:libfftw3-3.def
|
|
lib /def:libfftw3l-3.def
|
|
|
|
The single- and double-precision libraries use SSE and SSE2, respectively,
|
|
but should also work on older processors (the library checks at runtime
|
|
to see whether SSE/SSE2 is supported and disables the relevant code if not).
|
|
|
|
They were compiled by the GNU C compiler for MinGW, specifically:
|
|
i686-w64-mingw32-gcc (GCC) 4.9.1
