WebJan 11, 2005 · Hi, I’m compiling a large F90 application that uses the FFTW libraries for some operations. I’m using the current trial version of PGI Workstation 5.2 for x864-64 on a dual Opteron system. Currently the application segfaults when it accesses the FFTW functions. But if I compile a version using native FFT routines instead of FFTW, it works … WebApr 28, 2010 · I had similar problem. What helped was compiling the fftw libs with this help Compiling FFTW source in Visual studio. Actually more closely the problem was compiling my application Win 32 and trying to use x64 -libraries.

The builds on PyPI use mingw for the 32-bit release and the Windows SDK C++ compiler for the 64-bit release. The scripts should handle this automatically. If you want to compile for 64-bit Windows, you have to use the MS Visual C++ compiler.
WebJun 21, 2024 · I considered FFTW as a compile-time alternative, but I'd need to change how my data is ordered. The c2r transform in FFTW requires data contiguous in the halved direction. Simply transposing the data before FFT would likely cancel out any performance benefit from using FFTW. Update: I've been using PocketFFT for almost a year now. I … WebJun 3, 2016 · Compiling and installing SHTns. To compile SHTns, you need a C compiler and the FFTW library version 3.0 (or better 3.3) or later, carefully optimized and installed.
