Thanks for all replies.
I'll use inlining until I have figured out how to build a proper package.

I'm not a windows expert. You have C code file (not cc or cpp):
> R CMD SHLIB OrthoFunctions.c
and you use g++ compiler... ok, we can use c++ compiler for c.. but
it's looks like c++ code with c code inside:
> extern "C" {
Try it without "extern "C" and with gcc compiler instead g++.
regards,
Michael,
You are getting confused in compiler minutia when you could be concentrating
on your code. The inline package can help here.
Consider the snippet below which loads inline, defines your function body
sans headers etc and then uses the magic of inline to compile, link and load
your fun

Greetings,
I am trying to call simple C-code from R.
I am on Windows XP with RTools installed.
The C-function is
#include
#include
#include
#include
// prevent name mangling
extern "C" {
SEXP __cdecl test(SEXP s){
SEXP result;
PROTECT(result = NEW_NUMERIC(1));
double* ptr=NUMERIC_PO
