There are a few options to our configure script that we especially recommend on Windows:
#Intel visual fortran 运行 install
The simplest way to compile FFTW on Windows is probably to install the free MinGW Unix environment so that you can use the GNU C compiler (gcc). In particular, you can use the bench.exe program to benchmark a few typical sizes to get an idea of how they compare: bench.exe -opatient 64 4096 If you do compile FFTW yourself, we encourage you to compare the speed of the resulting executable with the gcc-compiled version that we provide above. Be cautious with the compiler flags-turning on every optimization under the sun usually makes FFTW slower.

#Intel visual fortran 运行 code
This may produce marginally faster code than the GNU C compiler, but is probably not worth it for most users. Intel C: you can also use the Intel compilers under VC++ (see below).VC++ 2005 may work, and VC++ 2010 has been reported to work. However, many older versions of VC++ generate incorrect code for FFTW when SSE/SSE2 is enabled. Visual C++: In the past, several users have contributed Visual C++ project files for FFTW which you can download below.We recommend this route because it produces native Windows executables/libraries, but lets you use our standard Unix build scripts and Makefiles, automatically picks good compiler flags, and so on. MinGW: this is a free Unix-like environment for Windows based on the GNU C compiler (gcc).If for some reason you need to compile FFTW yourself on Windows, rather than using the above DLLs, you have several options:

Lenarczyk): implib -a fftw3-3.lib libfftw3-3.dll On Visual Studio 2008 in 64-bit mode, and possibly in other cases, you may need to specify the machine explicitly: lib /machine:圆4 /def:fįor Borland C++, you instead need to use Borland's implib program, via (thanks to M. lib "import libraries" using the lib.exeprogram included with VC++. In order to link to them from Visual C++, you will need to create. You should be able to call them from any compiler. These DLLs were created by us, cross-compiled from GNU/Linux using MinGW the 64-bit version is possible thanks to the mingw-w64 project. We hope that these are sufficient for most users, so that you need not worry about compiling FFTW: We have created precompiled DLL files for FFTW 3.3.4 in single/double/long-double precision, along with the associated test programs.
#Intel visual fortran 运行 manual
You should, of course, first read the Installation on non-Unix Systems of the FFTW 3 manual (or the corresponding section of the FFTW 2 manual). (It was sent in by users, and has not been personally verified by us.) Please contact us if you have any additions or corrections. This document contains various information regarding installation of FFTW on DOS/Windows.
