Question related to usage etc, especially when encountering bugs or failure,
surely do.

Is that the official line?

I have two suggestion.
First is to (as a stop-gap measure) hard-code your path rather than the
expansions we compute at compile-time by asking functions such as
edd@max:~$ R -q -e 'cat(Rcpp:::LdFlags(), "\n")'
R> cat(Rcpp:::LdFlags(), "\n")
-L/usr/local/lib/R/site-library/Rcpp/lib -lRcpp
-Wl,-rpath,/usr/local/lib/R/site-library/Rcpp/lib
R>
R>
edd@max:~$
If you hardcode this in the Makevars you use, you should be fine. I guess
you could also use the same for inline's cxxfunction() etc.
Second, we are of course open to suggestions and improvements from smart
Windows users. Neither Romain nor I have much patience for Windows and don't
work on it, so changes are unlikely to come from us. So by all means, if you
have some time and interest to poke around please do so and report back. We
are always happy to incorporate changes as long as do not come at the cost of
making existing use patterns harder.

Sorry, I will not be able to make it this year. Maybe next year at Vanderbilt...
Cheers, Dirk
