Ahh ... is *that* why we're stuck on 4.2.1 for ever? I didn't realize that. Shoot, and all this time I was holding out for an upgrade ... perhaps when clang matures more it will save the day. > > I have heard that recent versions of the Xcode tools include clang and > clang++.

I reckon this can get tricky, and the package you build won't be able to run on "normal" mac/R, but ... you wouldn't have that either if you did the bootcamp route either. Or (2) you can try to work around this issue. Ian, are you instantiating a new Rcpp::Xptr and trying to register your own custom finalizer in one go? Is that why this is in your error stack trace " ... Rcpp::XPtr<Class, standard_delete_finalizer<Class> > ..."? Perhaps you can use the "normal" R (C) functions to wrap an external pointer and register its finailizer, eg: SEXP xp = R_MakeExternalPtr(your_ptr, R_NilValue, R_NilValue); R_RegisterCFinalizer(xp, your_custom_finalizer); Would that work as a bandaid for now? -steve -- Steve Lianoglou Graduate Student: Computational Systems Biology | Memorial Sloan-Kettering Cancer Center | Weill Medical College of Cornell University Contact Info: http://cbio.mskcc.org/~lianos/contact _______________________________________________ Rcpp-devel mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
