Installation for Smaug
----------------------

1. In your Makefile, someplace above the main list of C_FLAGS,
   include the following:

#IMC2 - Comment out to disable IMC2 support
IMC = 1

   Then directly below the list of H_FILES, add the following:
   [Note: BSD users - put a period in front of the word ifdef, and in front of the word endif]

ifdef IMC
   C_FILES := imc.c $(C_FILES)
   O_FILES := imc.o $(O_FILES)
   C_FLAGS := $(C_FLAGS) -DIMC -DIMCSMAUG
endif

2. Open mud.h

   Locate the following:

/*
 * Structure for extended bitvectors -- Thoric
 */
struct extended_bitvector
{
    unsigned int		bits[XBI];
};

   Directly below that, add the following:

#ifdef IMC
   #include "imc.h"
#endif

   Locate your pc_data struct, which should be in one of your main *.h files.

   Add the following to the end of it:

#ifdef IMC
    IMC_CHARDATA *imcchardata;
#endif

4. Open interp.c and locate the following section:

if ( !check_social( ch, command, argument )

   Add the following condition to whatever series of ifchecks exist there:

#ifdef IMC
	&&   !imc_command_hook( ch, command, argument )
#endif

5. Open comm.c and locate the following in main() :

    /* I don't know how well this will work on an unnamed machine as I don't
       have one handy, and the man pages are ever-so-helpful.. -- Alty */
    if (gethostname(hostn, sizeof(hostn)) < 0)
    {
      perror("main: gethostname");
      strcpy(hostn, "unresolved");
    }
    sprintf( log_buf, "%s ready at address %s on port %d.",	sysdata.mud_name, hostn, port );
    log_string( log_buf );

   Add the following beneath that:

#ifdef IMC
    imc_startup( FALSE ); // FALSE arg, so the autoconnect setting can govern it.
#endif

   Then further down in main(), locate the following:

    closesocket( control  );
    closesocket( control2 );
    closesocket( conclient);
    closesocket( conjava  );

   Add the following beneath that:

#ifdef IMC
   imc_shutdown( FALSE );
#endif

   Then in game_loop(), locate the following:

	/*
	 * Autonomous game motion.
	 */
	update_handler( );

   Directly ABOVE that, add the following:

#ifdef IMC
	imc_loop();
#endif

6. Open save.c and locate fread_char:

   In the case 'I': section, and right before the final break; add the follwing:

#ifdef IMC
           if( ( fMatch = imc_loadchar( ch, fp, word ) ) )
                break;
#endif

   Then in fwrite_char, locate:

    fprintf( fp, "End\n\n" );

   Directly ABOVE that, add:

#ifdef IMC
    imc_savechar( ch, fp );
#endif

   Then in load_char_obj(), locate the following:

    found = FALSE;
    sprintf( strsave, "%s%c/%s", PLAYER_DIR, tolower(name[0]), capitalize( name ) );

   Directly ABOVE that, add the following:

#ifdef IMC
    imc_initchar( ch );
#endif

7. Open db.c

   Locate free_char:

   Below this block of code:

	if ( ch->pcdata->subprompt )
	   STRFREE( ch->pcdata->subprompt );
	if(ch->pcdata->tell_history)
	{
		int i;
		for(i = 0; i< 26; i++)
		{
			if(ch->pcdata->tell_history[i])
				STRFREE(ch->pcdata->tell_history[i]);
		}
		DISPOSE(ch->pcdata->tell_history);
	}
   Add:

#ifdef IMC
	imc_freechardata( ch );
#endif

8. For users of copyover/hotboot ONLY:

   Locate do_copyover, and just before the buffers for the execl call are
   allocated, add the following:

#ifdef IMC
   imc_shutdown( FALSE );
#endif

8b: For users of SWR derivatives:

In your imccfg.h file, replace the CH_LEVEL line with the following:

#define CH_IMCLEVEL(ch)          ((ch)->top_level)

8c: For users of CalareyMUD 2.0 and 3.0:

In your imccgh.h file, REMOVE the CH_IMCLEVEL macro.
In imc.c, find the imc_adjust_perms function.
Replace it with this one:

void imc_adjust_perms( CHAR_DATA *ch )
{
   /* Ugly hack to let the permission system adapt freely, but retains the ability to override that adaptation
    * in the event you need to restrict someone to a lower level, or grant someone a higher level. This of
    * course comes at the cost of forgetting you may have done so and caused the override flag to be set, but hey.
    * This isn't a perfect system and never will be. Samson 2-8-04.
    */
   if( !IMCIS_SET( IMCFLAG(ch), IMC_PERMOVERRIDE ) )
   {
      /* This will default to MORT only - you will need to override this with "none" to
       * keep people you don't want using it off.
       */
      if( ch->pcdata->permissions == 0 )
	   IMCPERM(ch) = IMCPERM_MORT;
      else if( IS_SET( ch->pcdata->permissions, PERMIT_BUILD ) )
	   IMCPERM(ch) = IMCPERM_IMM;
      else if( IS_SET( ch->pcdata->permissions, PERMIT_ADMIN ) )
	   IMCPERM(ch) = IMCPERM_ADMIN;
      else if( IS_SET( ch->pcdata->permissions, PERMIT_SECURITY ) )
	   IMCPERM(ch) = IMCPERM_IMP;
   }
   return;
}

Return to the main IMC.txt file and continue where you left off.
