Interesting point. I guess I'm not sure what constitutes "your code", though. A lot of the mailing list examples use inline, which has a nice verbose=T option that shows the program source that includes all the needed header defns, as well as the necessary function definition wrappers that we often omit here. It also shows all the necessary switches for g++. The issue I see is that R takes the place of main(), and g++ requires a main() to successfully compile. I tried a trivial example, and I didn't have any luck compiling. Am I missing something here? cxxfunction(signature(x='numeric'), 'NumericVector xx(x);', verbose=T, plugin='Rcpp') ## copy Program source to file, edit for sanity ## flags below taken from cxxfunction output $ g++ -I/usr/share/R/include -I"~/R/x86_64-pc-linux-gnu-library/2.12/Rcpp/include" tmp.cpp -xian -- A man, a plan, a cat, a ham, a yak, a yam, a hat, a canal – Panama! _______________________________________________ Rcpp-devel mailing list Rcpp-devel@lists.r-forge.r-project.org https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
