You are right, the problem is related to the dispatch mechanism we use to
delegate calls to backends. In this case, it sounds as if you haven't
configured any fft backends.
You mention the windows binary release, which is configured / compiled
for use with Intel's IPP and MKL libraries. But then you are talking about
the source distribution, and mingw. To help you a little further it
is important to know what Sourcery VSIPL++ package you use, and how exactly
the command looks that raises the error. Are you configuring / building
Sourcery VSIPL++ yourself ? What commands are you using ?

Thanks,
		Stefan
