I have found out how do to this, after about an hour.

All you have to do is go in your ~cygwin\usr\include\sys directory, and place a .h file with the following in it.



#ifndef _SYS_DIR_H_
#define _SYS_DIR_H_

#include <dirent.h>

/*
* Backwards compatibility.
*/
#define direct dirent
#define DIRSIZ(dp) _GENERIC_DIRSIZ(dp)

#endif /* !_SYS_DIR_H_ */


Theren there is an error "cannot find -ldl"

There is something wrong with the "L_FLAGS" in the makefile, and without them, you cannot move or look in the MUD, but it will still start up. If anyone has any ideas, please help me.

It is a linking probleem. -ldl is required for dlsym support. SWFotE seems dependant on it, so I guess you better download it. I personally don't know much about it, so maybe someone else can tell you more.

Oh, and you shouldn't run anything that complains of a linker error, thats just not good practice.

It's actually impossible to run something that had linker errors. It's the linking phase that generates the executable and without a successful link, you have no program to run. Whatever was run was the old executable. As for being able to connect but not move or look around, that'd have to be made a bit more precise so that we can start diagnosing the problem.

You are correct Kyilyan. I'm not sure what I was thinking.

Anyways, a new one wont work, but I'm sure the old one probably works fine besides the one problem. Dlsym is essentially the command hook, and without it you won't be able to use commands unless you download the correct files needed or simply revert back to using the functions in tables.c . In order to do that, you would have to readd all of the DECLARE_DO_FUN's, as I believe they were removed.

Of course, if one were to want this fixed right, one could look over this part of our Makefile and adjust it as needed to fit:


afkmud: $(O_FILES)
	rm -f $(AFKMUD)
ifdef WINDOZE
	dlltool --export-all --output-def afkmud.def $(O_FILES)
	dlltool --dllname $(AFKMUD) --output-exp afkmud.exp --def afkmud.def
	$(CC) -o $(AFKMUD) $(O_FILES) afkmud.exp $(L_FLAGS)
else
	$(CC) -o $(AFKMUD) $(O_FILES) $(L_FLAGS)
endif
	echo "Done compiling mud.";
	chmod g+w $(AFKMUD)
	chmod a+x $(AFKMUD)
	chmod g+w $(O_FILES)


It shouldn't be overly difficult to figure out how to adapt that, but without the "WINDOZE" sections the dlsym code won't work in Cygwin.

What .h file? You need to install dlsym, or do Samson's fix.

It's most likely a Cygwin package (if you're using it) or a separate lib. Try Googling it.

Ok, since the google blew my mind (i'm still gonna try searching, just in case):

I don't have that text in my makefile, should I add it? it isn't AFKMUD, but FOTE (SWR, i believe, in the MAKEFILE). How can that be implemented? Again, sorry for being so annoying,

Nevermind, I found it. I changed it to WINDOZE and it gave the same error.

These are the important line, and are out of my makefile which runs on cygwin and has dlsym working fine.

	dlltool --export-all --output-def swr.def $(O_FILES)
	dlltool --dllname $(SWR) --output-exp swr.exp --def swr.def
	$(CC)  $(W_FLAGS) -o $(SWR) $(O_FILES) swr.exp $(L_FLAGS)


You'll have to adjust it slightly. Also, where ever you have -ldl, try removing it or commenting it out. It is unnessecary in cygwin.

If this doesn't work, please post your whole make file so we can see what your seeing.

Ok, I thought it did it, but It didn't. I couldn't get the Look and movements to work. When I tried to make the swr.exe file again it wouldn't, it got to fight.o and gave this:

fight.c:49:23: sys/dir.h: No such file or directory
make[1]: *** [o/fight.o] Error 1
make: *** [all] Error 2

What's Up with that?
