You didn't mention this change in the commit log. The description of fftwf appends "Single-precision version" to the description from fftw, but since your commit above, the fftw and fftwf packages are identical except on armhf, as far as I can tell. On armhf, the build now fails with "configure: error: NEON requires single precision". https://hydra.gnu.org/build/2674813/nixlog/1/tail-reload Can you take a look? Mark
