I just pulled the smaug src off this site, attempted to compile, and this is what is thrown at me.

I noticed this was mentioned earler, but never was given a solution. Anybody have any clues on this? Also, I am not a coder...yet.

Which source did you get - which filename exactly? The latest one doesn't seem to have any reference to RENAME in it.

http://www.gammon.com.au/files/smaug/smaug1.4a.sce.zip - 814 Kb - Source (only) for SMAUG server v 1.4a for Win32

Straight out of your downloads section. And I got it out today.

Took me a couple seconds of thinking, but I got it.

In the makefile, there are two lines commented.

#Uncomment the line below if you are getting undefined re_exec errors
#NEED_REG = -lgnuregex

#Uncomment the line below if you are getting undefined crypt errors
#NEED_CRYPT = -lcrypt

Uncomment them and its done. I belive crypt and rename are linked together. I got some more errors after this, but I post them tomorrow.

ok, I lied. It came back when I compiled again....no other changes. Renames are gone, but crypt still stands.

Crypt is used for password encryption. You can probably manage without it. Search for crypt on this forum, I'm sure we've been over this ground before. :)

Nope, never have, but I fixed the error. heres the solution

Make a crypt.c in your src. In crypt.c add

char *crypt(const char *key, char *salt)
{
return (char*)key;
}

In your makefile, add crypt.c and crypt.o in the proper places. Also uncomment this line.

NEED_CRYPT = -lcrypt

For rename

In misc.h

// to emulate Unix rename - we must delete the newpath first
int RENAME (const char * oldpath, const char * newpath)
{
remove (newpath);
return rename (oldpath, newpath);
}

What you need to do is add this below it:

#else

int RENAME( const char *oldpath, const char *newpath )
{
return rename( oldpath, newpath );
}

that should fix the rname/crypt errors. Hope this pice of info helps some out

I dunno... That *will* work, but it will also not encrypt the passwords in any way. I'd recommend download libcrypt, compiling it, and installing it on the system. That'd probably be a bit more secure. :)

Blah, who cares? If it works, it works ;)
