Update to previous post:

------------------------

I wrote a little C++ program with a system() call, calling the script without DTNTrigger to see if ::system(cmd.c_str()) call works in the first place. (Procedure exact same as in the dtntrigger.exe). I have tested this on both ubuntu and RaspberryPI (ARM based)

#include <csignal>

#include <ctype.h>

#include <stdio.h>

#include <stdlib.h>

#include <unistd.h>

#include <iostream>

using namespace std;

std::string _script = "bashScript.sh &";

std::string _shell = "/bin/sh";

int main() {

cout << "!!!Hello World!!!" << endl;

// call the script

std::string cmd = _shell + " " + _script + " " + "Node A" + " " + "/home/s116793/something";

cout << "The cmd is:"<<cmd<<endl;

::system(cmd.c_str());

return 0;

}

Script contents:

-----------

#!/bin/sh

echo "Hello guys.."

python /home/s116793/triggered.py

Output

------

!!!Hello World!!!

The cmd is:/bin/sh bashScript.sh & Node A /home/s116793/something

sh: 1: Node: not found

/bin/sh: 0: Can't open bashScript.sh

Observations:

------------

1) The bashscript.sh is in the same path as the executable in /Debug and it has 'full' permissions (chmod 777). I tried googling it seems to be a known problem for different reasons, not sure what's the problem here. Any expert advice?

2) Something wrong with the way I call? Can someone run this on their system and post some example here?

Thanks.
