You are making it difficult for us to help you as we have no idea about your
code.  You have one advantage: you can look at our working packages.

Take RcppAnnoy.  It has one templated class, instantiating three different
Rcpp Modules objects, which are then loaded via

   ## ensure module gets loaded
   loadModule("AnnoyAngular", TRUE)
   loadModule("AnnoyEuclidean", TRUE)
   loadModule("AnnoyManhattan", TRUE)

The one C++ is pretty simple too: it has no repeated symbol, class, module,
or whatever names and loads.
