trouble loading config file

no-reply@allegro.cc (William Labbett) — Sun, 17 May 2015 20:51:17 +0000

Hi,

just trying to get a config file to load.

Here's the bit of code which calls the load function :

/**********************************************************************/
   /**************** Section : load configuration file. ******************/
   /**********************************************************************/
   
   config_manager.load_config_file("configuration/tpos_configuration_file.cfg", log);
   
   if(config_manager.init_okay() != GREEN_FLAG)
   {
     /* add clear up code */
     return 0;
   }

Here's the class with the load function :

#SelectExpand
  1class ConfigManagerClass
  2{
 
 ALLEGRO_CONFIG *cfg;
 
 int init_okay_flag;
 
 public:
  9
 ConfigManagerClass() : cfg(NULL)
 {
    
 13
 }
 
 void load_config_file(const char *filename, Rabbit_Log& log)
 {
    cfg = al_load_config_file(filename);
   
  log.write_message_number();
  log.write_string("About to load configuration file (");
  log.write_string(filename);
  log.write_string(").");
  log.end_message();
  
  log.write_message_number();
  if( cfg == NULL )
  {
   log.write_string("Failed to load it.");
   init_okay_flag = RED_FLAG;
   
  }
    else 
  {
   log.write_string("Loaded it successfully.");
   init_okay_flag = GREEN_FLAG;
  
  }
  log.end_message();
   
 }
 
 int get_integer(const char *key, int *integer_to_get)
 {
    const char *string = NULL;
  
    string = al_get_config_value( cfg, NULL, "p1");
  
  if(string == NULL)
  {
       return ERROR_1;
    }
    else
  {
     return atoi(string);
  }
  
 }
 
 
 int init_okay()
 {
   return init_okay_flag;
 }
 
 66};

Here's the log file :

MESSAGE :    0   : Log file opened
MESSAGE :    1   : Initialised Allegro System.
MESSAGE :    2   : Initialised true type font addon.

Here's my directory structure (for some evidence so you've something to go on) :

Any allegro code detectives fancy helping me work out why the cfg file won't load??

Windows uses

folder\myfoler

*NIX uses:

folder/subfolder

So for windows you would write "folder\\myfolder" in the c string (two \\ = one because you're escaping the first backslash, IIRC)

It's Allegro he's passing the string to, and it understands both separators I believe. Windows does too. *nix is case-sensitive, but that doesn't look like the problem either.

You can try posting your cfg file and we can look at it and try loading it ourselves, because your tpos_001 exe is in the directory above your config file, and so it looks like it should work. Oh yeah, please stop hiding your file name extensions, and attach the full size image next time, it's too hard to read.

You sure about that? I'm pretty sure I've had (back)slashes, and "./subdirectory/file" vs /subdirectory/file" (no dot) both cause me problems in A4 and A5 before.

Otherwise, why would this exist?

char *fix_filename_slashes(char *path);

I always use forward slahes on Windows and never had problems with this before. Most native Windows C and C++ functions should treat / and \\ equally for pathes.

The problem here, I believe, is that any path starting with a / is interpreted as an absolute path on Unix. Using "subdirectory/file" should work on all systems and represent a relative path.
