Hi,

I get a crash, when I call al_init().

Hoaven't programmed for a long time. Is it something obvious?

Here's the code :

#SelectExpand
  1class InitialisationClass 
  2{
  3
 public:
 
    
    uint32_t version;
    int init_okay;
  
  InitialisationClass(void) : init_okay(0), version(0)
    {
       ;
    }
  
  InitialisationClass(ofstream &log)
    {
     cout << "here 1.\n";
       if( al_install_system(ALLEGRO_VERSION_INT, atexit) == false)
       {   
   
      log.write("Unable to install the allegro system.\n", 39);
          return;
       }
 
       cout << "here 2.\n";
 
       if(al_init_ttf_addon() == false)
     {
        log.write("Unable to install true type font addon.\n", 41);
    return;
     }
   
   init_okay = 1;
    }
  
  /* Constructor for when the log file couldn't be created. */
 
    InitialisationClass(int dummy)
    {
     cout << "Calling al_install_system().\n";
       if( al_init() == false)
       {
      cout << "here 10.";
      return;
   }
   
   cout << "Called it.\n";
 
       if(al_init_ttf_addon() == false)
     {
        return;  
     }
  
     init_okay = 1;
    }
  
 private:
 
 int print_version_number(void)
 {
    ;
 }

I can't read what's in the image, but the console shows "here 1" but not "here 2"?

It worked fine in C just now.

  if( al_install_system(ALLEGRO_VERSION_INT, atexit) == false)
    printf("phooey\n");
  else
    printf("yay\n");
  return 0;

They all watch too much MSNBC... they get ideas.

You probably have a different version dll than the version your program was compiled with interfering or you have mis-matched headers. Delete old dlls and re-copy new ones. Use Dependency Walker if you need to.

King Piccolo will make it so Then I could just flip it with some sweet, sweet matrix math. In either case, I’ll ride this wagon until the wheels fall off. Thanks to those that keep it running

Thanks Arthur,

I worked out what's wrong.

When I declared the instance of the InitialisationClass which this constructor is being called for, I didn't call the default constructor. i think this was causing the problem.

Thanks.
