What version of Smaug, exactly, did you attempt to compile?

Using this file:

http://www.smaugmuds.org/index.php?a=files&s=download&cid=9&fid=165

... under Lion, I got this:

make -s smaug

There were errors (warnings), but not the ones you got.

Basically I edited interp.c and cast a few arguments (as in the line numbers above) to be (long) where appropriate.

Then I got this:


iMac5:src nick$ make
make -s smaug
  Compiling o/interp.o....
  Compiling o/liquids.o....

  Compiling o/sha256.o....
sha256.c:35:20: error: endian.h: No such file or directory
make[1]: *** [o/sha256.o] Error 1

I edited sha256.c and changed the start to read:



#include <stdio.h>
#include <string.h>
#include <sys/param.h>
#if !defined(WIN32)
#include <sys/cdefs.h>
#if defined(__FreeBSD__)
#include <sys/endian.h>
#else
#include <machine/endian.h>
#endif
#endif
#include "sha256.h"

(line in bold changed).

Then I got this:


iMac5:src nick$ make
make -s smaug
  Compiling o/sha256.o....
  Compiling o/shops.o....
  Compiling o/skills.o....
  Compiling o/special.o....

  Compiling o/weather.o....
ld: unknown option: -export-dynamic
collect2: ld returned 1 exit status
make[1]: *** [smaug] Error 1

I edited Makefile and changed as follows:


#Some systems need this for dynamic linking to work.
#EXPORT_SYMBOLS = -export-dynamic

That is, comment out that line.

Also change:


smaug: $(O_FILES)
        rm -f smaug
        $(CC) -export-dynamic -o smaug $(O_FILES) $(L_FLAGS)

to be:


smaug: $(O_FILES)
        rm -f smaug
        $(CC) $(EXPORT_SYMBOLS) -o smaug $(O_FILES) $(L_FLAGS)

Then it worked:


make -s smaug

Hey Nick,

Thanks for all that info! To answer your questions it is the dbsc2.5.2. Just as a note It compiles just fine under ubuntu gnome terminal.

The makefile looks like this..

Anyone know why this error is accuring?

At the line in question in mud.h change:


typedef unsigned char			bool;

to:


//typedef unsigned char			bool;

Then you get heaps of warnings, and finally:


comm.c:29:19: error: crypt.h: No such file or directory

This is looking a little less well-maintained than SmaugFUSS, because of all the warnings.

If it compiles under Ubuntu, try finding the crypt.h you have on the Ubuntu PC, and making a copy for the Mac. Don't know if that will work or not.

Lukem Fri 07 Oct 2011 01:25 AM #4

So I did some research and found that crypt.h is a library libcrypto that has been deprecated in lion.

http://stackoverflow.com/questions/7475914/libcrypto-deprecated-on-mac-os-x-10-7-lion

So now I've just got to find how to install this libcrypto or alter the code in a way to use something else...

Nick Gammon Australia Forum Administrator Fri 07 Oct 2011 04:05 AM #5

Try commenting out the line:


#include <crypt.h>

like this:


//#include <crypt.h>

Lukem Mon 10 Oct 2011 03:07 AM #6

Then I get this error:

I am however going to try your way of compiling smaugFUSS too.

Lukem Mon 10 Oct 2011 03:13 AM #7

Also, for smaugFUSS what integer variable(s) did you change to long ints exactly?

Lukem Mon 10 Oct 2011 03:13 AM #8

In interp.c that is.

Nick Gammon Australia Forum Administrator Mon 10 Oct 2011 06:14 AM #9

Well for a message like this:


interp.c: In function ‘void interpret(CHAR_DATA*, char*)’:
interp.c:564: warning: format ‘%06ld’ expects type ‘long int’, but argument 9 has type ‘__darwin_suseconds_t’

I get to line 564, count my way to the 9th argument, and cast it to long.

Ok, I've spent some time trying to figure this out. I've looked at how to cast a struct as a long and have yet to get any valid information. What I see at 564 as the 9th argument is.. time_used.tv_usec And it setup as a struct.. sort of. struct timeval time_used; Is this correct how I'm following the code? If so how do I set this to long? I did struct timeval{ long time_used;}; and didn't get very far, tried a few other tries and needless to say, didn't have much luck.

LucasM Wed 19 Mar 2014 03:11 AM #11

So I revisited this issue, just for fun and happy to say I was able to get this working.

1.
mud.h line 98 comment out
//typedef unsigned char bool;

2.
comm.c line 29 change
#include <crypt.h>
to
#include <unistd.h>

3.
In Makefile on line 79 you have to remove the -lcrypt from the string
$(CC) $(L_FLAGS) $(USE_IMC) -o dbsaga $(O_FILES) -lcrypt

Not sure who this will help or how relevant this is anymore, just thought I'd post this since there might be a case someone has a mac they wants to test dbsc2.5.2.

Now to see what I should start coding with first, maybe I'll try making a new race or something.

Nick Gammon Australia Forum Administrator Tue 25 Mar 2014 08:00 PM #12

Thanks for the update.
