Document implementation fftw3.dll and fftw3f.dll

[parksj10]

Hi, sorry for the N00b issue, but I'm having trouble getting the FFTW implementations to work, I've downloaded the dlls and put them in the root directory, and it seems that this code

public static bool LibraryExists()
        {
            try
            {
                var ptr = NativeMethods.fftwf_malloc(8);
                NativeMethods.fftwf_free(ptr);
                return true;
            }
            catch
            {
            }

            return false;
        }

is where the dll is attempting to be found/added, but I can't find any reference in the project how/where to put this dll so it is actually imported and used.

Thanks!
Josh

Make sure that the native FFTW dlls are inside the directory of the executable.

If you are using the Visual Studio solution without any modifications, the output path is defined in fftbench.csproj as <OutDir>$(ProjectDir)..\bin\$(Configuration)</OutDir>, which means the fftbench.exe executable will be in the directory [project root dir]\fftbench\bin\Release (or Debug, if you are compiling in debug mode).

ahhhh, just came here to post that I figured out a work around, which is exactly what you said!!! thanks a lot @wo80 for reference for others (to dynamically load the dll)

Soln --> right click --> add --> existing file --> find dll (need to show "All Files")

Then make it copy during build
dll --> right click --> properties --> Copy to Output Directory --> Copy or Copy if newer
