I'm a little tired, so this may be a stupid question. I am trying to add some code, and I am getting pages of this during linking:

o/imc.o(.bss+0x0): In function `imcstrlcpy(char*, char const*, unsigned)':
/home/mud/darkwars/dwadmins/src/imc.c:124: multiple definition of `imcwait'

I've checked all of the include files, making sure they have all the #ifdef __FILE__ in them, and they do. I'm positive this is something simple, but I'm just not thinking clearly. I'm sure that there are not multiple calls of every single function, as these are all included in the same .c file

Given that the source lines of the first and second definitions are the same, I'd make sure you're not including imc.o twice in the linking phase or something like that.

Yeah, that was it. Thanks, too out of it to notice something simple like that. I was use

C_FILES = account.c act_comm.c act_html.c act_info.c act_move.c act_obj.c \
	  act_wiz.c alias.c arena.c autobuild.c backup.c ban.c \
	  boards.c bounty.c build.c changes.c channels.c clans.c cleanup.c color.c comm.c \

O_FILES = $(patsubst %.c,o/%.o,$(C_FILES))

H_FILES = $(wildcard *.h) 

ifdef IMC
   C_FILES := imc.c md5.c $(C_FILES)
   O_FILES := imc.o md5.o $(O_FILES)
endif

Thanks.
