[Rcpp-devel] Fwd: List of uniform_int_distribution objects

Hi all, I have decided to follow Dirk's advice and use more classical STL containers rather than Rcpp::List one. It works for me but I admit that I am still in the dark as to why the Rcpp::List way doesn't work. Thus, I consider this topic closed. Thanks. Anguel -Original Messag

[Rcpp-devel] Fwd: List of uniform_int_distribution objects

In fact I mightily misspoke (apologies). The Rcpp list is of course not meant to be exported out of the Rcpp code but to be used inside another Rcpp function. But the code fails with a similar message: Error in dyn.load("/var/folders/12/bqytpkx93w97r3s3_h9q9k_0gn/T//Rtmpm2tVkx/sourcecp

[Rcpp-devel] List of uniform_int_distribution objects

Hi everybody, 1. I am trying to create an Rcpp list, each of whose elements contain an uniform_int_distribution object. 2. My understanding is that since an uniform_int_distribution object is a non-SEXP one, I need to create a specialization of wrap() first. 3. To this end, I am using

Re: [Rcpp-devel] NLopt linking problem

Greetings and Salutations, Try setting the environment variable NLOPT_HOME with the location of the NLopt library and then add to the Makevars.win file: PKG_CFLAGS = -I"$(NLOPT_HOME)$(R_ARCH)/include" PKG_LIBS = -L"$(NLOPT_HOME)$(R_ARCH)/lib" -lnlopt_cxx Sincerely, JJB From: rcpp-devel-boun..

Re: [Rcpp-devel] NLopt linking problem

Hi Dirk, Thanks for the quick reply. I'm aware of the nloptr CRAN package, but not using that package as the objective function (and gradient) being optimized as to be in C++. Defining the function in R and then calling back and forth between R and C++ using the nloptr package is too costly time

[Rcpp-devel] NLopt linking problem

Dear Rcpp-Devels, List, I'm struggling with building a Rcpp package linking to the NLopt library (*http://ab-initio.mit.edu/wiki/index.php/NLopt *). I'm on Windows and I've the following files in \src: - Makevars.in - Makevars.win - Rcpp_pr
