Thank you very much for your answer. I have changed the DESCRIPTION file to
include:
LinkingTo: Rcpp, BH
(before: LinkingTo: Rcpp) but it continues giving the same build error.

I think you want to check your DESCRIPTION file. I believe you need to have
the 'LinkingTo:' option to also include BH.

Hello,
I know this question has been answered before (and I have searched for it), but
I cannot figure out a solution:
I want to use boost with Rcpp, basically to be able to use numbers with a
higher precision than a double. I am comfortable using the inline package for
small c++ functions, I have never used Rccp per se. I have created a skeleton
with convolve, and it works. I have added a new function:
// We can now use the BH package// [[Rcpp::depends(BH)]]
#include <Rcpp.h>#include <boost/math/common_factor.hpp>
using namespace Rcpp; // [[Rcpp::export]]int computeGCD(int a, int b) {
return boost::math::gcd(a, b);}
and when I try to compile, it fails (basically, the compiler does not find
where boost is). I have then run in R:
Sys.setenv("PKG_CXXFLAGS"="-I C:/Program~Files/boost/boost_1_57_0/")
which allows me to go a bit more into the build, but the compile fails when
reaching the #include <boost/math/common_factor.hpp> above, since it does not
know where boost is (boost is at C:/Program~Files/boost/boost_1_57_0/ I have
not compiled it, but just extracted with 7-zip and copied and pasted the
corresponding files into this subfolder).
