Hi Joe, Just FYI.
Ubuntu 14.04+ provides both posix and openmp libraries if you want to test there ( static and shared ). The package is: libfftw3-dev. File List: http://packages.ubuntu.com/trusty/amd64/libfftw3-dev/filelist For Windows, I think you could tweak the fftw build script to generate a static pair of libs at least, possibly DLL's also. I don't know about Mac. 73's Greg, KI7MT On 02/01/2015 01:17 PM, Joe Taylor wrote: > Hi Bill, > >>> Note also that if we have success with using OpenMP elsewhere in the >>> program, we'll need to use an FFTW library compiled with >>> "--enable-openmp". >> I am hoping that is not the case and that normal multi-threaded FFTW3 >> can be used in parallel to OpenMP, otherwise other builders of WSJT-X >> are going to have several hurdles to overcome. > > OK.
