Rcpp on OSX?

And e.g. the complete lack of follow- up from R Core about the suggested additions to the R CMD INSTALL functionality (cf r-devel in the summer). Rcpp builds and works for me under Linux and Windows -- the only platforms I have access too -- and I use it daily.
See Brian's e-mail - it builds on very specific setups of some Linux systems only (Windows is a different story since you have a separate makefile for that and it's a closed system).
I had asked a friend who uses OS X to test this, but he hadn't gotten around to it. So OS X is simply untested. On Windows and Linux I now install one copy of Rcpp and have other package compile and link against it. | a matter of setting some flags to get it to work.

If this is portable, we can surely talk about making it more generic.
The R_ARCH part is just the icing on the cake - the main problems are hard-coding flags like "-shared", how to compile so's, wrong names for the package library etc. etc. Using a Makefile is always a very last resort that one should take only if you are sure that you won't need anything from R (not true here) and you are really sure that you know what you're doing.
If David is willing to test this, we can probably sort this out over a few off-list emails. I'd be up for that. | $(USERLIB): Rcpp.o | $(SHLIB_CXXLD) -o $(USERLIB) $^ $(SHLIB_CXXLDFLAGS) $(ALL_LIBS) | | .PHONY: all clean userLibrary | | clean: | rm -f $(OBJECTS) $(SHLIB) $(USERLIB) That is overall a pretty small change.
Small? Wow - it's a completely different approach...
So I don't see the need for the belligerent tone above, especially given that I have no access to OS X.
Hm... I don't see any mention of 'altruistic' in the dictionary for 'belligerent' so I hope it's just a typo ;). Cheers, S
Thanks, Dirk
