al_init crash

William Labbett

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;

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.

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.
