Interesting. I should take a look. I had similar needs for Rcpp as R doesn't provide a 'pkg-config'-alike function for add-on packages. Rcpp provides a header and a library for its users. These need to be found by the user's Makefiles, so following a suggestion Simon once made, what we now do is to provide Rcpp:::CxxFlags() Rcpp:::LdFlags() which aren't even in the NAMESPACE file and meant to be called directly from configure scripts or Makefiles as in (using either little $ r -e'Rcpp:::CxxFlags()' -I/usr/lib/R/site-library/Rcpp/lib...@ron:~$ $ Rscript -e 'Rcpp:::LdFlags()' -L/usr/lib/R/site-library/Rcpp/lib -lRcpp -Wl,-rpath,/usr/lib/R/site-library/Rcpp/lib$ (and notice the lack of a trailing 'backslash-n'). Could there be scope for generalising this up into R proper for 2.11 or later?
