Jupp, it is very basic. In fact so basic that i failed to find the
problem the first time i looked over the code.
The problem is this. On line 17 you declare zone_table as being a
pointer to an extern struct. However, you arent using the correct
operand ( -> ) to extract data from that pointer on line 23. Instead you
use the operand . which is used when you want to extract data from
objects of structs.
The correct code would be :
23 if (zone_table[i]->number == vnum)
It might also be that zone_table is defined as an array or something in
the code ( Remember that CircleMUD is jam packed with arrays ). However,
in any case, that operand error has got to be fixed.
If you dont get the point, you can contact me at my student mail account
since it seems we are going to the same university =)
The reason i write this response in english is purely because of that i
cc this to the CircleMUD mailing list.
