Hi Rcpp-Users and Rcpp-Devels,
I just build an RcppArmadillo project on my computer using gcc-4.8.1 and the
newest Version of RcppArmadillo. I got some warnings I cannot explain to
myself. It builds the library and installs it. Nevertheless I would like to
know more about my warnings:

The FinmixModel class looks like:
HEADER:
#include <RcppArmadillo.h>
// [[Rcpp::depends(RcppArmadillo)]]
#include <string>
class FinmixModel {
public:
Rcpp::List parList;
arma::rowvec weightV;
arma::uvec tV;
bool indicFix;
unsigned int K;
unsigned int r;
/* ctor */
FinmixModel(const Rcpp::S4& classS4);
/* dtor */
~FinmixModel();
};
CC:
#include <RcppArmadillo.h>
#include "FinmixModel.h"
FinmixModel::FinmixModel(const Rcpp::S4& classS4) {
/**
* As the parameters 'par' can have very differing implementations
* they are kept in a general Rcpp::List object which is then
* decomposed in main code.
*
*/
parList = classS4.slot("par");
weightV = Rcpp::as<arma::mat>(classS4.slot("weight"));
/**
* 'T' can be 'NA' if the model has no repetitions (Binomial)
* in this case this attribute is set to an 1 x 1 vector
*
*/
tV = Rcpp::as<arma::uvec>(classS4.slot("T"));
indicFix = Rcpp::as<bool>(classS4.slot("indicfix"));
K = Rcpp::as<unsigned int>(classS4.slot("K"));
r = Rcpp::as<unsigned int>(classS4.slot("r"));
}
FinmixModel::~FinmixModel(){}
>From looking into the files RcppArmadilloForward.h, fn_as_scalar.hpp and
>class.h it seems that there is something about typedefs, but I am not sure. It
>seems to me just not right, that all these warnings occur in my build output.
