Alright, I hate to do this to you people, but I couldn't find an exact answer to my question on the forums. I'm trying to add:

Altanos Compass Display
-----------------------

Original code from the Altanos codebase.
Modified for stock Smaug compatibility by Samson of Alsherok.

The I got off of http://www.alsherok.net. Now, here is my problem. I know some java and visual basic, so I have a general idea of how the code works, however I know no C/C++. I'm getting this on compile: (with cygwin)

Compiling o/act_info.o
act_info.c: In function 'print_compass':
act_info.c:916: warning: implicit declaration of function
'IS_EXIT_FLAG'
act_info.c:931: warning: implicit declaration of function
'MXP_ON'
act_info.c:931: error 'MXP_TAG_ROOMNAME' undeclared (..ob.
definition here..)
(Each undec. ident. is reported only once...)
act_info.c:932: error 'MXP_TAG_ROOMNAME_CLOSE' undeclared
(..ob. definition here..)
act_info.c:935: warning: implicit declaration of function
'IS_EXIT_FLAG'
make[1]: *** [o/act_info.o] Error 1
make: *** [all] Error 2

So I search all the c and h files, and I found no IS_EXIT_FLAG function. Am I missing some all important snippet that everyone has? Oh, and I am using SmaugFUSS with a few other snippets in, none of which effect this one in anyway.

Remove lines relative to MXP unless your mud uses it. If you have not added your self (which, if you know no C/C++ would be a feat in itself) then your dont have it because SmaugFUSS doens't come with it. As for the declarations (sry, not quite sure, I've been up 26+ hours :P) is either warning you of conflicting definitions, called the function wrong, don't have the function, or having no prototype definition at all. I'd say post the relevent sections of code (910-920 or so should do it). Again, safely remove references to MXP.

Wow, that was quick :P. Well, once again, I dont know too much about C, so thats that. I had downloaded AFKMud the other day, and so on a whim I did a search through the code. It is FILTHY with references to IS_EXIT_FLAG. So I found the line in mud.h and copied it over to the same general spot:

#define IS_EXIT_FLAG(var, bit) xIS_SET((var)->exit_info, (bit))

Well, I now longer get the imp dec errors anymore, instead i get:

error: request for member 'bits' in something not a structure or union

Everytime it calls IS_EXIT_FLAG. The code thats giving problems is this:

void print_compass( CHAR_DATA *ch )
{
EXIT_DATA *pexit;
int exit_info[] = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
static char * const exit_colors [] = { "&w", "&Y", "&C", "&b", "&w", "&R" };
for( pexit = ch->in_room->first_exit; pexit; pexit = pexit->next )
{
if( !pexit->to_room || IS_EXIT_FLAG( pexit, EX_HIDDEN ) ||
( IS_EXIT_FLAG( pexit, EX_SECRET ) && IS_EXIT_FLAG( pexit, EX_CLOSED ) ) )
continue;
if( IS_EXIT_FLAG( pexit, EX_WINDOW ) )
exit_info[pexit->vdir] = 2;
else if( IS_EXIT_FLAG( pexit, EX_SECRET ) )
exit_info[pexit->vdir] = 3;
else if( IS_EXIT_FLAG( pexit, EX_CLOSED ) )
exit_info[pexit->vdir] = 4;
else if( IS_EXIT_FLAG( pexit, EX_LOCKED ) )
exit_info[pexit->vdir] = 5;
else
exit_info[pexit->vdir] = 1;
}
set_char_color( AT_RMNAME, ch );
ch_printf_color( ch, "\n\r%s%-50s%s %s%s %s%s %s%s\n\r", MXP_ON(ch) ? MXP_TAG_ROOMNAME : "", ch->in_room->name,
MXP_ON(ch) ? MXP_TAG_ROOMNAME_CLOSE : "", exit_colors[exit_info[DIR_NORTHWEST]], exit_info[DIR_NORTHWEST] ? "NW" : "- ",
exit_colors[exit_info[DIR_NORTH]], exit_info[DIR_NORTH] ? "N" : "-", exit_colors[exit_info[DIR_NORTHEAST]],
exit_info[DIR_NORTHEAST] ? "NE" : " -" );
if( IS_IMMORTAL( ch ) && IS_PLR_FLAG( ch, PLR_ROOMVNUM ) )
ch_printf_color( ch, "&w-<---- &YVnum: %6d &w----------------------------->- ", ch->in_room->vnum );
else
send_to_char_color( "&w-<----------------------------------------------->- ", ch );
ch_printf_color( ch, "%s%s&w<-%s%s&w-&W(*)&w-%s%s&w->%s%s\n\r", exit_colors[exit_info[DIR_WEST]], exit_info[DIR_WEST] ? "W" : "-",
exit_colors[exit_info[DIR_UP]], exit_info[DIR_UP] ? "U" : "-", exit_colors[exit_info[DIR_DOWN]], exit_info[DIR_DOWN] ? "D" : "-",
exit_colors[exit_info[DIR_EAST]], exit_info[DIR_EAST] ? "E" : "-" );
ch_printf_color( ch, " %s%s %s%s %s%s\n\r\n\r",
exit_colors[exit_info[DIR_SOUTHWEST]], exit_info[DIR_SOUTHWEST] ? "SW" : "- ", exit_colors[exit_info[DIR_SOUTH]],
exit_info[DIR_SOUTH] ? "S" : "-", exit_colors[exit_info[DIR_SOUTHEAST]], exit_info[DIR_SOUTHEAST] ? "SE" : " -" );
return;
}

I'm also willing to give up and try a different snippet if anyone has any suggestions :P

:P Added that line already, see? And about the MXP, should I just hack it right out?

Yes, just take it out. For example:
ch_printf_color( ch, "\n\r%-50s%s %s%s %s%s %s%s\n\r",  exit_colors[exit_info[DIR_NORTHWEST]], exit_info[DIR_NORTHWEST] ? "NW" : "- ",
exit_colors[exit_info[DIR_NORTH]], exit_info[DIR_NORTH] ? "N" : "-", exit_colors[exit_info[DIR_NORTHEAST]],
exit_info[DIR_NORTHEAST] ? "NE" : " -" );


Double check that your doors have flags compatible with xflags. You can try just removing the "x" in "xIS_SET". If it compiles properly afterward, then it just meant that your exit flags are not extended flags.

I would also recommend that you try on the board that is listed in the instruction from the snippet. Samson is more likely to be able to give you info there.

I'd also like to point out that if there are problems with snippets from my site it is usually far more productive to come to our forums and discuss the issue there. One of us is far more likely to see it.

As for being "FILTHY" with IS_EXIT_FLAG macros, you did attempt to siphon it from a codebase which isn't strictly compatible with Smaug anymore. These things are bound to happen. Greven has the right advice though, just take the x out of the xIS_SET part of the macro and it will work fine.

Regarding the compass code itself, I looked over it again and fixed the compatibility issues.
