You can probably fix some of these errors (at least the first one) by including <complex.h> (not <complex>) before <fftw3.h>. This will make fftw use the C native complex type instead of its own. This will allow float to complex assignment for example. If you really want a 'pure' C++ version you will need to reinterpret_cast whenever you use a function that expects or returns a C++ complex. It won't make your code any more readable. IMHO the C++ complex type (a template class trying to hide its implementation) is completely useless and a real PITA, and a good example of the pedantic attitude that is typical of the C++ crowd. Nobody with even just a minimal knowledge of scientific computing would want to hide the implementation of complex types - almost all classical algorithms (e.g. the FFT) depend on it being cartesian. A second source of problems with the vocoder is the mixing of floats and doubles. There is no good reason to use a double FFT here.
