Hi,

Would it be possible to have the FFTW3 library available ?

Pre-built can be found here:
http://www.fftw.org/install/windows.html

Cheers,
Gilles

   Hi Gilles,

   I see that library is a zip. You can download it and unpack during the build using 2-line script.

   Great, dwl and extraction are working.

   for MSVC compilation, where can I find the lib tool for generating .lib files from .def files ?

   You need this when the library is compiled using MinGW and you need to link it with MSVC object files. In this case, you need to convert .def files (generated by MinGW) (describing dll exports) into .lib files, which are necessary for linking with MSVC.

   Activate Visual Studio command prompt by calling this batch in, say, "Install script" or "Before build script":

   "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat"
   

   and lib.exe will become available.
