Hei :slight_smile:

I already did that.

My problem is how to integrate that in a program of my own.
For example,

#include <stdio.h>

#include “interface.h”
#include <unistd.h>
#include <stdlib.h>

#include “gis.h”

int main(int argc, char **argv) {

printf(“Argv[0] = %s\n”, argv[0]) ;

G_gisinit(“prot1”) ;

printf(“G_program_name => %s\n”, G_program_name()) ;

// if (G_parser(argc, argv))
//exit (-1);

// ask_interface() ;

}

I don 't understant why this doesn’t work :frowning:

Output :
seabiscuit@ubuntu:~/Estagio/GRASS_Prototipo1$ ./prot1
Argv[0] = ./prot1

bla

seabiscuit@ubuntu:~/Estagio/GRASS_Prototipo1$

(this stopped because I did Ctr C)

This is what I’m having trouble understanding …
Help please :slight_smile:

I’m getting really desperate with grass …
I want to use its libraries in my C program, but I can’t seem to even

Is there any manual that you recommend to helo me out?

Help / Rescue would be very much appreciated!!
