The extern "C" looks suspicious. What happens if you don't include it ?
e.g.
#include <Rcpp.h>
#include <gretl/libgretl.h>
#include <gretl/kalman.h>
or perhaps:
#include <gretl/libgretl.h>
#include <gretl/kalman.h>
#include <Rcpp.h>

Hi,
I am having trouble getting Rcpp to compile c++ files including headers
from the gretl statistical libraries
for instance, here are the first lines of a test cpp file I have been
trying to compile:
#include <Rcpp.h>
extern "C" {
#include <gretl/libgretl.h>
#include <gretl/kalman.h>
}
now, here is the result of a make command in linux (debian), with the
error messages focussing on the lines of code where the #include are
located:
jean@desktop:~/Documents/code experiments/gretl$ make

any guidance would be really appreciated!
many thanks,
