Hello.
I'm new to using netbeans as a C++ ide under ubuntu.
I've been developing a program to interface with playerstage.
Right now I'm updating some code from 2yrs ago so I'm almost starting from scratch and the code has been reduced to very few lines.
Here they are
Code:

/*
 * File:   main.cpp
 * Author: erupter
 *
 * Created on May 16, 2012, 6:22 PM
 */

#include <GL/glut.h>
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <math.h>
#include <time.h>
#include <libplayerc/playerc.h>
#include "variables.h"


int main(int argc, char **argv)
{
  int result=0,i;
  double min_angle=0, max_angle=0, angular_res=0, min_range=0, max_range=0, range_res=0, frequency=0;
 
  set_defaults();
 
  if ((execute_command_interpreter(argc,argv)))
    return -1;

  result=network_setup();
 
  if (result){
    printf("Network setup error\n%s",network_errors[result]);
    return -1;
  }

  playerc_ranger_get_geom(sonar);
  playerc_ranger_get_config(sonar,&min_angle, &max_angle, &angular_res, &min_range, &max_range, &range_res, &frequency);
  i=0;

  printf("Sensor config:\nMin_angle %g\nMax_angle %g\nAngular_res %g\nMin_range %g\nMax_range %g\nRange_res %g\nFreq %g\n",min_angle, max_angle,angular_res,min_range,max_range,range_res,frequency);
  printf("Setting new config\n\n");
  playerc_ranger_set_config(sonar,-90,90,1,0,8,0.05,15);
  playerc_ranger_get_config(sonar,&min_angle, &max_angle, &angular_res, &min_range, &max_range, &range_res, &frequency);
  printf("Sensor config:\nMin_angle %g\nMax_angle %g\nAngular_res %g\nMin_range %g\nMax_range %g\nRange_res %g\nFreq %g\n",min_angle, max_angle,angular_res,min_range,max_range,range_res,frequency);

  close_connections();

  return 0;
}


I'm omitting code for some functions.
Anyway up to about 40 minutes ago I got it debugging nicely.
Now the debugger doesn't start (or most probably it crashes).

If I load a simple stupid hello world, gdb works ok.
In my app no way.
I started a new project and just pasted the relevant code, but no joy.
How can I debug the debugger behaviour under netbeans???

I debugged the very same program with gdb in console without any problem, so it is Netbeans somehow.

Can anybody at least suggest a way to show relevant messages from the debugger?


Edit:
after an uninstall&reinstall cycle I first got it working again, then broke it again.
So I deleted my home user ./netbeans folder and the debugger works again without reinstalling.
So something's going on with what's saved in my users config.

edit2:
tried a diff on the .netbeans folder but too many things got changed.
It's something in the config subfolder though...

Hi,

try to see what's in the gdb log (http://wiki.netbeans.org/GdbLog)
or just open it (main menu/window/debugging/debugger console)

Thank you very much Egor, now I'm at least in a position to understand what's happening!

Now I have to understand it.
