That was just what I needed! All it took was adding a single line before
the call to mkString (and adding one more header file):
#include <Rinternals.h>
#include <Rembedded.h>
SEXP hello() {
return mkString("Hello, world!\n");
}
int main(int argc, char **argv) {
SEXP x;
Rf_initEmbeddedR(argc, argv);
x = hello();
return x == NULL; /* i.e. 0 on success */
}
When I run the executable with
% myR/bin/R CMD hello_r -q --vanilla
...it goes without a hitch.
Many thanks!
