When installing packages containing code to compile, R eventually calls
R CMD SHLIB. Same thing happens with inline C++: it gets stored in a
temporary file, compiled into a *.dll using R CMD SHLIB and then loaded
using dyn.load().
Write the following into a file named hello.c:
#include <R.h>
#include <Rinternals.h>
SEXP hello(void) {
SEXP ret = PROTECT(allocVector(STRSXP, 1));
SET_STRING_ELT(ret, 0, mkChar("hello"));
UNPROTECT(1);
return ret;
}
>From within R, setwd() to the directory containing hello.c and run:
tools::Rcmd('SHLIB -n hello.c')
tools::Rcmd('SHLIB hello.c')
What do the commands print? Does the second command fail?
(Let's Cc: R-help@r-project.org in case people with more experience
debugging Windows problems have a better idea what's going on.)
