I downloaded the rom code, ported me believe, and used the makefile that was suggested, what I got was an error on the comm.c, telling me that, to the best of my knowledge, something is undeclared, or declared in a way that is messing the whole thing up.. Here's my makefile too:

<pre>

CC = gcc
PROF = -O -g
NOCRYPT =
C_FLAGS = -Wall $(PROF) $(NOCRYPT)
L_FLAGS = $(PROF)

O_FILES = act_comm.o act_info.o act_move.o act_obj.o act_wiz.o alias.o \
ban.o comm.o const.o db.o effects.o fight.o \
handler.o hunt.o interp.o magic.o \
music.o note.o races.o recycle.o \
save.o skills.o special.o tables.o update.o \

rom: $(O_FILES)
rm -f rom
$(CC) $(L_FLAGS) -o rom $(O_FILES)

.c.o: merc.h
$(CC) -c $(C_FLAGS) $<

Which ROM did you use exactly? Which operating system are you using? Cygwin or something else?

I am using windows 95, with cygwin. As to the rom code, I used a win port from a friend, and then downloaded the one from this site, and have not been able to figure out exactly what is wrong with the comm.c... I'm currently on a amd-k6, 200mhz machine with 16 meg ram, and not a clue as to why I didn't a clean compile. Also, I changed the makefile I had to match yours, and still came up against the error.

The missing things sound like they are from these include files:


#if defined(unix)
#include <fcntl.h>
#include <netdb.h>
#include <netinet/in.h>
#include <sys/socket.h>
#include "telnet.h"
const   char    echo_off_str    [] = { IAC, WILL, TELOPT_ECHO, '\0' };
const   char    echo_on_str [] = { IAC, WONT, TELOPT_ECHO, '\0' };
const   char    go_ahead_str    [] = { IAC, GA, '\0' };
#endif

They won't be included if "unix" is not defined.

In the file "Makefile" make sure this line is there, with the -Dunix at the end ...



C_FLAGS =  -Wall $(PROF) $(NOCRYPT) -Dunix
