GLPK ?

Hi everybody,
I am using GLPK in C++ programs like :
glp_prob *lp = glp_create_prob();
glp_tran *tran = glp_mpl_alloc_wksp();
glp_mpl_read_model(tran, "..\\MyModel.mod", 1);
glp_mpl_read_data(tran, "..\\MyModel.dat");
glp_mpl_generate(tran, NULL);
glp_mpl_build_prob(tran, lp);
glp_simplex(lp, NULL);
glp_mpl_postsolve(tran, lp, GLP_MIP);
glp_create_index(lp);
int index = glp_find_col(lp, "MyVariable");
double optimalValue = glp_get_row_prim(lp, index);
When using with big input data, the solving time becomes very important. So,
I would like to use another solver like CLP. For example, in the above
source, it would replace the ligne "glp_simplex(lp, NULL);" by the call of
the new solver.
I found references for Symphony or Osi but I did not find clear examples
doing what I am looking for.
Maybe, someone have met this problem or you could have valuable advices or
suggestions that I could test...
Nicolas
