[Rcpp-devel] Re-using C++ code from a package with modules and defining linker flags using Rscript
Thanks for both your replies. I got it working the way I wanted. If someone's interested, a simple example with two packages can be downloaded here: http://www.ucl.ac.uk/~uctpjyy/downloads/RcppEx.zip QuadFunc defines a C++ class that is used in C++ code in QuadFuncVec. Jelmer
