Ah, I think libraries in 'Requires.private' should also be propagated, otherwise, we got: $ pkg-config --cflags gnutls = Package 'zlib', required by 'GnuTLS', not found If not propagated, other packages use gnutls have to add zlib to inputs, even they never use it.
I just pushed a commit to propagate zlib for gnutls, hope I'm not wrong ;-) > > So as I understand this, there is no need to propagate the zlib input. > > Or am I getting it wrong? > > Andreas
