Dear Forum,

I'm having some difficulties configuring my Rom2.4[Heavily Modified] codebase to start on a Linux[Debian] OS. I've been, over the past week, reading separate forums regarding this problem. From what I collected, It states that I need to add -lcrypt to the linker lines in the makefile itself.

Currently the Mud is running on a FreeBSD server just fine. I understand that FreeBSD is more of a Linux/Unix OS and from what I gather, my makefile has all the settings set so it can run via Unix just fine.

Here is the makefile I have edited to run via Linux even though it still isn't compiling properly.

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

O_FILES = act_comm.o act_enter.o act_info.o act_move.o act_obj.o act_wiz.o \
alias.o ban.o comm.o const.o db.o db2.o effects.o fight.o flags.o \
handler.o healer.o interp.o lookup.o magic.o magic2.o \
music.o recycle.o save.o scan.o skills.o special.o tables.o \
update.o mob_cmds.o mob_prog.o olc.o olc_act.o olc_save.o bit.o \
mem.o string.o olc_mpcode.o remort.o bank.o board.o auction.o quest.o \
games.o kit.o freeze.o gods.o

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

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

At the bottom of the makefile via ".c.o: merc.h" I removed -Dunix -DNOCRYPT. I imagine those two statements themselves allowed my mud to compile fine on my FreeBSD server. Even with leaving those there...and also removing them. It still didn't compile. Now mind you, when I compile on FreeBSD, the errors I'm about to present to you do not show, but when I compile on Debian, this is what it says:

Any help on this subject would be greatly appreciated. My head is beginning to hurt from working on this. Thanks again for being available, I typically don't use forums.

Can you show us some of those lines in tables.h? Everything else is just a warning.

Debian is in fact just as much of a "Linux/Unix OS" as FreeBSD is; it's just a different distribution.

On your FreeBSD machine, type gcc --version
then do the same on your Debian machine.

What you are likely to see is that Debian is using a much more recent version of gcc, maybe even version 4, which is much, much stricter about sloppiness. It doesn't let you do things that older versions let you get away with.

Really, the newer version is helping you; the kind of errors it catches, if due to sloppiness, are often an indication of not understanding really what is going on. Or, it is also often an indication that you might have made a mistake you didn't mean to make, and it's helping you find it.

Zeno is right, though; you should post some of those lines from tables.h to see what the problem is.

By the way, the crypt library has nothing to do with the problem so far. You are failing to compile and haven't gotten to the link stage yet; linking is where crypt comes into play. (Linking is when you group everything together: the files you just compiled and the external libraries they use.)

I assume something like this:
extern const struct flag_type apply_types[];

Should be:
extern const struct flag_type * apply_types;


Google the error message for more details.

Thank you. I was able to get tables.h to work perfectly with it. Now I'm having a few awkward errors with act_comm.c. Now I'm sure this isn't that last of them, but at least I'll be able to start going through the source code and fixing them. Here is the error:

act_comm.c:2085: error: request for member 'independent' in something not a structure or union
act_comm.c: In function 'do_clantalk':
act_comm.c:2202: error: request for member 'independent' in something not a structure or union
act_comm.c:2302: error: request for member 'name' in something not a structure or union
act_comm.c:2311: error: request for member 'hall' in something not a structure or union

What exactly does that mean? An example of the code from act_comm.c:2085: is:

if (!is_clan(ch) || clan_table[ch->clan].independent)

How do I fix these errors? Again, I really appreciate all the help. Was quite overwhelming.

In act_comm.c, does tables.h get included before or after mud.h? (Or: does mud.h include tables.h at the very beginning? Or before the structure clan_type is defined?)


EDIT: also, try putting the single line:
struct clan_type;
above the clantype array declaration.

These are the included' files atop act_comm.c:

#if defined(macintosh)
#include <types.h>
#else
#include <sys/types.h>
#include <sys/time.h>
#endif
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <time.h>
#include "merc.h"
#include "interp.h"
#include "recycle.h"
#include "tables.h"

There is no mud.h in my source code. Rom2.4. Perhaps you meant merc.h? If so, there is no include headers in that file.

Thanks for this help, I know it's a bit time-consuming.

Oh yeah, I forgot this was ROM-based, not SMAUG-based... anyhow.

Well, so much for the include idea... one more thing about that though. Could you find where struct clan_type is defined?

Also, did you try the line of code I mentioned?

Looks' like it's defined within tables.c:

#include <types.h>

#include <sys/types.h>

#include <stdio.h>
#include <time.h>
#include "merc.h"
#include "tables.h"

/* for clans */
const struct clan_type clan_table[MAX_CLAN] =
{
/* name, who entry, death-transfer room, independent */
/* independent should be FALSE if is a real clan */
{ "", "", ROOM_VNUM_ALTAR, TRUE },
{ "loner", "[ {RL{ro{wn{De{rr{Rs{x ] ", 3007, TRUE },
{ "Jungle", "[ {GJu{gng{Gle{x ] ", 1213, FALSE },

Oh, that's the array itself that's defined; I meant the type. Somewhere there should something like like:
typedef struct CLAN_TYPE { // or something
  // some data members
} clan_type;

It'll probably be in a .h file.

As for the line, put it right above the line
extern const struct clan_type clan_table[MAX_CLAN];

Nope, that didn't work sadly. Ok, only things I can find while searching for clan_type is this which is located right under the array types in tables.h:

extern const struct flag_type * position_flags[];
extern const struct flag_type * ac_type[];
extern const struct bit_type * bitvector_type[];

struct flag_type
{
char *name;
int bit;
bool settable;
};

struct clan_type
{
char *name;
char *who_name;
sh_int hall;
bool independent; /* true for loners */
};

struct position_type
{
char *name;
char *short_name;
};

struct sex_type
{
char *name;
};

struct size_type
{
char *name;
};

struct bit_type
{
const struct flag_type * table;
char * help;
};

Perhaps this is where it's stuffing up?
