Ive compiled alot of different codebases so far, and the only one thats giving me alot of trouble is dystopia. This is the smaug board but this error is kind of like some of the ones that I had with smaug last night so here goes.

Near the end of the make, when it reaches comm.c, i get several implicit declarations. They are as follows.

comm.c:48:48: execinfo.h: No such file or directory
comm.c: In function 'lookup_address':
comm.c:1141: warning: implicit declaration of function 'gethostbyaddr_r'
comm.c: In function 'iBacktrace':
comm.c:1554: warning: implicit declaration of function 'backtrace'
comm.c:1556: warning: implicit declaration of function 'backtrace_symbols'
comm.c:1556: warning: assignment makes pointed from integer without a cast
make: *** [comm.o] Error 1

I had to hand type all of that (havent figured out how to copy paste yet) heh. Anyhow, my makefile is as follows.


CC = gcc
NOCRYPT = -DNOCRYPT
C_FLAGS = -Wall -g $(NOCRYPT)
L_FLAGS = -lz -lpthread -rdynamic

O_FILES = act_comm.o act_info.o act_move.o act_obj.o act_wiz.o kav_wiz.o \
kav_soundex.o kav_fight.o kav_info.o board.o build.o social-edit.o \
fight.o arena.o mccp.o db.o x-socials.o interp.o handler.o \

update.o const.o save.o special.o string.o jope.o msp.o comm.o \
jobo_quest.o jobo_update.o jobo_save.o jobo_comm.o jobo_fight.o \
jobo_act.o jobo_wiz.o jobo_util.o jobo_shop.o

merc: $(O_FILES)
rm -f dystopia
$(CC) -o dystopia $(O_FILES) $(L_FLAGS)
chmod g+w dystopia
chmod g+w $(O_FILES)

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

clean :
rm -f *.o

could anyone please help me figure out whats wrong? =P Thanks.

The problem is actually in comm.c, not your makefile. First problem is you either dont have the execinfo.h file, or more likely just dont have it where the code expects it to be. The warnings can be ignored pretty much unless you want to clean up the code so you dont get em anymore. What you need to fix so your code compiles is the defined path for execinfo.h because its not where the code expects to find it. I havent played with the dystopia codebase at all so Im not sure exactly where it thinks the file is supposed to be and can't help you much beyond pointing out the problem. Maybe Nick or another of the admins here will have better info on that part of the problem.

I probalbly have to fix where it thinks it is then, because dystopia-1.4.tar.gz didn't come with any file called execinfo.h, the problem is i have no idea what to do with this, im semi new to compiling. Like you said hopefully nick or someone whos compiled dyst1.4 can help me out heh

I haven't compiled it, however if you tell me where you found it I could try.

What system are you using? Cygwin? Linux?

In either case you should be able to copy and paste the errors. In Cygwin click on the icon in the very top-left corner, select Edit -> Mark and then click and drag to select the text you want. Then hit Enter.

I got it from ftp.game.orc, its the only version of dystopia downloadable without going into the archive files. I heard those ones are all buggy so i got 1.4. Im using Cygwin. Thanks for telling me how to copy error messages, heh, helps alot. I can show you the whole thing now, so here goes...

It wasnt like this initially though. First at the end it gave me something about not being able to find -lcrypt, so i removed it from makefile (thats the error i got last night with smaug and i removed -lcrypt and smaug worked so i thought well why not with this) then it started giving me crypt errors.. so i added NOCRYPT = -DNOCRYPT to makefile, and now I cant figure out what to do with this new error thats come up, aka the one as shown above.

I presume you mean ftp.game.org - can you give the exact directory - I can't find it there.

Right, your major problems are the following 3 things:


comm.c:47:48: execinfo.h: No such file or directory
comm.c: In function `lookup_address':
comm.c:1140: warning: implicit declaration of function `gethostbyaddr_r'
comm.c: In function `iBacktrace':
comm.c:1553: warning: implicit declaration of function `backtrace'
comm.c:1555: warning: implicit declaration of function `backtrace_symbols'


If we look in comm.c we see that execinfo.h is included near the start:


#include <execinfo.h>   // internal backtraces.


This gives us a hint about the third error (the backtrace one) because without the header file it probably won't recognise things in it.

I commented that line out.

Next, I see there are problems in iBacktrace, however I notice that further up the call to iBacktrace is commented out:


/*    signal(SIGSEGV, iBacktrace); */


If we are not calling it, we hardly need the function itself, so you could remove it or comment it out. Here is one way of doing that ...



#if 0
/*
 * To do internal backtracs at crashes
 */
void iBacktrace(int iSignal)
{

... blah blah blah ...

}
#endif


The final problem is the gethostbyaddr_r one. I see from my Linux header file the following comments:


/* Reentrant versions of the functions above.  The additional
   arguments specify a buffer of BUFLEN starting at BUF.  The last
   argument is a pointer to a variable which gets the value which
   would be stored in the global variable `herrno' by the
   non-reentrant functions.  */
extern int gethostent_r (struct hostent *__restrict __result_buf,
                         char *__restrict __buf, size_t __buflen,
                         struct hostent **__restrict __result,
                         int *__restrict __h_errnop) __THROW;

extern int gethostbyaddr_r (__const void *__restrict __addr, __socklen_t __len,
                            int __type,
                            struct hostent *__restrict __result_buf,
                            char *__restrict __buf, size_t __buflen,
                            struct hostent **__restrict __result,
                            int *__restrict __h_errnop) __THROW;


I'm not sure you really need the re-entrant call to gethostbyaddr so let's change it to the non-re-entrant one and try that ...


  struct hostent *from = 0;
//  struct hostent ent;
//  char buf[16384]; // enough ??
//  int err;

  thread_count++;

//  gethostbyaddr_r( darg->buf, sizeof(darg->buf), AF_INET, &ent, buf, 16384, &from, &err);
    gethostbyaddr( darg->buf, sizeof(darg->buf), AF_INET);



That compiled OK - I didn't actually run it.

I got that, but it still works. What happens is that under Cygwin it makes a file called dystopia.exe but the last thing in the make file tries to change the permissions on dystopia. You can change that to dystopia.exe in the make file, or just ignore it. You are now ready to run it.

Yup it did, just got home heh. Seems that every dystopia codebase works if you tweak the gethostbyaddr_r like you had me tweak it. Thanks for all your help.

This thread is over a year old. I would prefer you started a new thread for a new set of errors. If you did you would have seen this request:

Please tell us:


  • Which version you are compiling (eg. SMAUG FUSS, SMAUG 1.4a with MXP)

  • Which operating system and compiler you are using (eg. Linux, Windows with Cygwin, Windows with Visual C++)
