When trying to compile SWR on Cygwin, I keep getting the following error, no matter what I've been told by anyone I know.. :

make swreality
make[1]: Entering directory `/home/Adam1/swr/src'
gcc -c -g3 -Wall save.c
save.c: In function `load_char_obj':
save.c:913: warning: suggest explicit braces to avoid ambiguous `else'
save.c: In function `load_corpses':
save.c:2055: warning: assignment from incompatible pointer type
save.c:2057: dereferencing pointer to incomplete type
save.c:2059: dereferencing pointer to incomplete type
make[1]: *** [save.o] Error 1
make[1]: Leaving directory `/home/Adam1/swr/src'
make: *** [all] Error 2

If anyone can help, thanks a lot!

It is hard to debug from just the error messages. Can you post the 10 lines preceding line 2059 in save.c, and indicate which are lines 2055, 2057 and 2059?

Do you have this line near the start of save.c, without any #ifdef around it?


  #include <dirent.h>


If not, put it there. If there is an #ifdef remove it. ie, change:


#ifndef WIN32
  #include <dirent.h>
#endif


to


  #include <dirent.h>

I got it to compile under Cygwin by adding one line. This is what the start of save.c looks like for me ...


#include <sys/types.h>
#include <ctype.h>
#include <stdio.h>
#include <string.h>
#include <time.h>
#include <unistd.h>
#include <sys/stat.h>
#include <dirent.h>
#include "mud.h"

#define direct dirent  // add this line
