No, as I tried to explain in great length. The minimal example should always
be
$ export PKG_CXXFLAGS="...some header location..."
$ export PKG_LIBS="...some libs..."
$ R CMD SHLIB foo.cpp
and inline / cxxfunction can be of help if you know these values.

I also had look at RcppGSL and why I needed to muck with the generator. My
installation must have had a test version. Once I reinstalled RcppGSL from
either SVN or the released version, the normal behaviour worked ie
funx <- cxxfunction(signature(par="numeric"), gslrng,
plugin="RcppGSL",
includes = "#include <gsl/gsl_rng.h>")
for the example posted earlier. That is how it should work -- we employ
RcppGSL, we want an additional header which I list, and the rest 'just works'.

Well theree is source, and there are package using it. There was a prior
discussion on the list here in December. But that is about it at this point.
Patches always welcome! Some user have in fact sent us documentation patches....
