Top Forums Programming Problem with system("command") Post 302461618 by agama on Monday 11th of October 2010 09:04:00 PM

The system() function runs the command in a separate process. When you run a second call, it gets its own process and anything (environment, working directory etc.) set in the first process isn't available.

Try putting the two commands together
Code:
system( "cd ~/Agostino/program; test" );

This will change directories and then run the test command; all in the same process.

Hope this helps.

It occurs to me that the system() function usually executes /bin/sh, and depending on your environment the shell installed as /bin/sh might not support the [/code]~[/icode] as meaning "home directory." Best to pass that information into your programme, or have the programme use get the value of HOME from the environment and use it.

allegro_exit(3alleg4)						  Allegro manual					     allegro_exit(3alleg4)

NAME
allegro_exit - Closes down the Allegro system. SYNOPSIS
#include <allegro.h> void allegro_exit(); DESCRIPTION
Closes down the Allegro system. This includes returning the system to text mode and removing whatever mouse, keyboard, and timer routines have been installed. You don't normally need to bother making an explicit call to this function, because allegro_init() installs it as an atexit() routine so it will be called automatically when your program exits. Note that after you call this function, other functions like destroy_bitmap() will most likely crash. This is a problem for C++ global destructors, which usually get called after atexit(), so don't put Allegro calls in them. You can write the destructor code in another method which you can manually call before your program exits, avoiding this problem. SEE ALSO
