I don't fully understand. If it is correct without it, but breaks with it --
then why do you bother including it?

The R API (in C) uses renaming defines, so "error()" is sometimes / used to
be "Rf_error()".
I presume that the include order you have here has something to do with this:
one file may have undefined it. It may be as simple as moving the include
for progress.hpp _above_ the othres.
But what you have is more difficult to debug than it needs to be. I would try
from just Rcpp, and adding one component at a time.
