The compiler is complaining about a missing constructor. (This is on
purpose: rings and polynomials are reference counted and centrally
managed in order to avoid two mathematically equal objects within one
program.)

Use references to polynomials rings if you want to pass them around. For
instance, you could declare your structure like this:
struct parameter { cl_N z0; cl_UP& p; }
and, once you have created and finalized your cl_UP_N object q, create a
parameter object like this:
parameter param = {1, q};

hope this helps
