Hi there,
I'm sorry if I a send it for second time, I've just subscribed for the list.
I am trying to interface c++ code in R and make a package. With R CMD SHLIB
the dll was created, but when I try R CMD check, I am getting 'undefined
reference to..' linkage error messages.
The relevant c++ source from conf-infomap.cpp:
#include "conf-infomap.h"
#include "R.h" // R functions
#include "Rinternals.h"
#include "Rmath.h" // R math
#include "Rdefines.h"
using namespace std;
using std::cout;
using std::cin;
using std::endl;

*resamples, double *conf) {
int ret = confInfomap(seed[0],file,attempts[0],resamples[0],conf[0]);
if(ret == 0)
Rprintf("cluster map has been written to %s\n", file[0]);
R_FlushConsole();
R_ProcessEvents();
return; // Return Nothing.
}
}

Now when I run R CMD check, in file 00install.out I am getting the
