[Rcpp-devel] linking Rcpp with external GSL library
Kevin Ushey was right: just had to recompile the external library with -fPIC. Good to know that I could just copy everything into src and avoid such issues. Thanks!

Your problem may not be with your compile your Rcpp code but rather with | the way the GSL was built on that system -- you need a dynamic library. Looking more carefully, it seems that your use of libinterp2d may be the issue. It is a static library, and that may be your problem. Easiest fix is to copy its code into your package. Higher-end solution would be to make a shared library out of libinterp2d but you'd also have to distribute that for use by others.
