Generally logs are in the log folder..

I think at this point you'll want to run gdb for more accurate results.

Hanaisse is right, gdb will probably lead you to the answer quickly if you can follow the tutorial and use it effectively. Essentially, you need to figure out why you are failing to read a particular file. Without your boot log there is no way for us to determine what file that might be.

Have you added any fread_word() function calls, or modified the saving/loading of any particular object (mobs, classes, system data, etc)? If not, it seems likely you have corrupted some data somewhere that gets saved, though having filenames and an idea of what you changed would be the best. What commands did you add?

Ok, I can not get it to create a core dump :( I added the -g3 to the l_flags and c_flags .. Am I missing something ?

I alos editied the etc/secturity/limits.conf and added * soft core 10000 to it to allow for large core dumps, then I loged out and back in to make the change stick.

Did you make clean?

Are you saying the error during startup is not producing any core files? They'll be in your main folder /Dystopia/ (or whatever it is.

Did you find the log files yet?

You got an error message because you ran it with the arguments "file Dystopia" when it is expecting a port number.

What I normally do to debug is, change to the area directory, and then do gdb, like this:


cd ../area              # it needs to run in the area directory
gdb ../src/Dystopia     # or whatever the executable is

(gdb) run 4000          # run with port 4000

Issue found I think..
In the other code fread_number is defined as
unsigned long long int	fread_number	args( ( FILE *fp ) );


But in the dystopia 2 code it is defined as
int   fread_number       (FILE * fp);


Now if I change the code from the old mud to
unsigned long long int	fread_number	( FILE *fp );

I get

db.c:2268: error: conflicting types for ‘fread_number’
dystopia.h:3969: note: previous declaration of ‘fread_number’ was here


Any help here is greatly appreciated

Code 01 means the code is executing exit(1) somewhere.

Is this log still showing up?

In your case gdb didn't show much because the MUD didn't actually crash, it chose to exit, as Zeno said. If you haven't found the problem, you can still find why it calls exit. First make your own exit function:


void my_exit (int status)
  {
  exit (status);
  }


And put a function prototype in mud.h or whatever it is called:



void my_exit (int status);


Then go through the rest of the code (using grep will help) and change every instance of:


exit (1);


to:


my_exit (1);


(And of course any other numbers you find).

Just don't change the one inside my_exit. ;P

Then fire up gdb again, and before typing "run" type in "break my_exit". That will put a breakpoint on your my_exit function. Then type "run" or "run 4000" and let it rip. Then when it tries to exit it will end up in my_exit. Then type "bt" to get a backtrace to see exactly where in the code it is calling exit.

Put the actual function (my first box) only once in the code (eg. comms.c) otherwise the linker will complain it finds more than one of them. The function prototype I mentioned, which you put in your .h file, tells the other functions to expect it to be found at link time.
