I m including a fortran90 program that is not mine in my C++ project .
In the first stept I try to call the function by their name_() and i get the error "undefined reference to mp_mpi_cartesian_init_ "by dispalying the symbol of the obj file (using nm) i found that the function are called by their module as module_function_ so i add the module name and i Get the same problem but between fortran obj such as "Constants.f90:(.text+0x36): undefined reference to __powi4i4"
here is the c++ code :
#include <iostream>
#include <complex>
using namespace std;
extern"C" {
void mod_save_wave_mp_read_it_psi_(int * it,complex<double>* psi_E1E2 );
void mod_mpi_cartesian_mp_mpi_cartesian_init_( );
extern int mod_mpl_h_mp_iproc_ ;
}
int main(){
complex<double> psi_local[512*24*512*24];
int it ;
mod_mpi_cartesian_mp_mpi_cartesian_init_();
cout << "proc :" << mod_mpl_h_mp_iproc_ << "avant lecture\n";
mod_save_wave_mp_read_it_psi_(&it,psi_local);
cout << "psi ="<< psi_local[0] << "poiur le proc "<<mod_mpl_h_mp_iproc_ <<"\n";
}
and this is an exemple of a module :
MODULE mod_save_wave
USE mod_constants
USE mod_MPI_CARTESIAN
USE mod_time_mesure, ONLY : tempsEcoule
USE mod_input_data, ONLY : Nt_laserPsansLaser
USE mod_input_data, ONLY : n_phi, n_rho1_seg, n_rho2_seg
USE mod_input_data, ONLY : Nt_periode, save_periodique
