As Dirk suggests, just don't expect trouble-free operation between Rcpp and MSVC code. Since the API is simple enough, I'd personally use the old-fashioned R SEXP API in this case. g++ -m32 -I"C:/R/R-3.1.1/include" -I"C:/R/R-3.1.1/library/Rcpp/include" -I"C:/SAM/ssc-sdk-2014-1-21" -c RcppSSC.cpp -o RcppSSC.o g++ -m32 -shared -s -static-libgcc -L"C:/R/R-3.1.1/bin/i386" -L"C:/SAM/ssc-sdk-2014-1-21/win32" -o RcppSSC.dll RcppSSC.o -lssc -lR > library(Rcpp) > dyn.load("RcppSSC.dll") > ssc.module <- Module("RcppSSC", PACKAGE="RcppSSC") > ssc <- ssc.module$RcppSSC > s <- new(ssc, "pvwattsv1") s$exec() Log Notice: precheck input: variable 'file_name' required but not assigned time -1 [1] FALSE > > In the context of the SSC library, maybe. > > Note that the example below uses C language code (and there is a reason) > > But what you are overlooking is that in general you CANNOT mix code from > Visual Studio and MinGW for purposes of Rcpp -- and in general you CANNOT > mix > C++ code from different compilers.
