I tried to dynamically load a c++ function. Everything seems to be OK
when dyn.load() is  executed but then I get this error

Error in .C("integral", sumInMean, sumInVar, boundError,
numberSampleClasses,  : 
        C/Fortran function name not in load table

The code of the function is something like this:

#include <cmath>

extern "C" {
#include "/usr/local/include/gsl/gsl_statistics_double.h"
#include "/usr/local/include/gsl/gsl_randist.h"
#include "/usr/local/include/gsl/gsl_roots.h"
#include "/usr/local/include/gsl/gsl_sf_erf.h"
#include "/usr/local/include/gsl/gsl_math.h"
#include "/usr/local/include/gsl/gsl_integration.h"

void integral( arguments ){

I compile with:

g++ -c integral.C -fPIC -I/usr/local/include/gsl -o integral.o; R CMD
SHLIB integral.o

What could go wrong? The function modify its arguments ( the arguments
are  pointers )

I put my function with the C header directives in extern{}.

gsl is a library written in C, so I put the gsl's header directives also
inside extern{}.

I placed in my compiling directory a Makevars file with this content:

PKG_LIBS = -lm -lgsl -lgslcblas

and my R code looks like:
