[Symphony] Fwd: Compiling symphony with one callback

[Haroldo Gambini Santos]

Follows the code:
#include <coin/OsiSymSolverInterface.hpp>
#include <coin/symphony.h>
#include <sym_constants.h>
#include <sym_macros.h>
#include <sym_cg_u.h>

int user_find_cuts(void *user, int varnum, int iter_num, int level,
                    int index, double objval, int *indices, double *values,
                    double ub, double etol, int *num_cuts, int *alloc_cuts,
                    cut_data ***cuts);


int main(int argc, char **argv)
{
    OsiSymSolverInterface *sym = new OsiSymSolverInterface();

    sym->parseCommandLine( argc, argv );

    sym->loadProblem();

    sym->branchAndBound();

    return(0);
}

int user_find_cuts(void *user, int varnum, int iter_num, int level,
                    int index, double objval, int *indices, double *values,
                    double ub, double etol, int *num_cuts, int *alloc_cuts,
                    cut_data ***cuts)
{
    printf("hello.\n");

    return USER_SUCCESS;
}

Hi,

I'm starting to build a code with SYMPHONY, mainly based in the
"Walkthrough..." example of Michael Trick.

To start I've just included a callback to insert cuts, but it appears
that is is not being called.

In Trick's example it only defines the function, but there is no
sym_set_user_callback (something like that) as I expected.

Although my (small) code compiles fine, the callback is not being called
(put a printf inside it).

What additional step should I do ?

Cheers,

Haroldo
