I don't think that matters. Partial upgrades should work (and derivatives may rely on it). >> This package is the problem.

I'm talking about the dependency from ardour to libfftw3_single3. The dependency from libfftw3-dev doesn't matter here. >> fftw3 maintainers: to fix this you either need to provide a symbols >> file, or pass a suitable -V option to dh_makeshlibs so the shlibs file >> contains a stricter dependency. > > Please be more explicit about the expected outcome (i.e. the stricter > dependency you keep mentioning). Please read policy 8.6 which describes most of this more fully. The goal is for dpkg-shlibdeps to generate a dependency like "libfftw3-single3 (>= 3.3.5)" for any package which uses fftwf_make_planner_thread_safe. This is needed otherwise you may get a linker error like ardour does, and it's is done by using the symbols or shlibs systems as described in policy 8.6. Thanks, James
