Hello, first off I apologize if this is in the wrong section, I was unsure as to where to post it.

I've been attempting to compile mud source code, and after sorting through all the build errors I find myself with a strange error no matter which code I'm trying to execute.
After the build, I go to the area folder and type ../src/(executable)

It loads a list of things and then gives me this error.
copyover_recover:fopen: No such file or directory
I've compiled numerous muds by now and they all give me the same error, it seems to be searching for a copyover.data file that is just not there.

I tried creating a blank copyover.data file but that also does not seem to help, it gives me:
<*> The world spins <*>
Segmentation fault

Any help would be greatly appreciated,
Mat

Which MUD exactly? Can you give a link to where you got the source from?

As Nick said, the source location will help. You may also just be able to post the copyover_recover function.

Thanks for the quick replies,
I got the code from http://www.mudfiles.com/modules.php?name=Downloads
(Click codebases, click Linux)
I tried Age of Heroes, Children of the Night, Seeds of Hate, Godwars 1996, and Utopia Type Final, they all give me the same errors.
I'm currently on Ubuntu 10.04 64bit.
I also have Windows XP (32bit) on a separate partition, so I installed Cygwin and tried the Smaug FUSS code you have here, that didn't give me the same error, but it did say something about IMC2 not being on automatic mode, having to manually connect.
I tried extracting and compiling the other source codes through cygwin but I still got that copyover error, I can post the section of copyover_recover code if you let me know which parts you need.

Sorry if anything sounds somewhat idiotic, I'm rather new to this and theres quite a lack of information on these subjects, atleast where I've been looking.

Appreciate the help guys,
Mat

When you run the servers you should use the 'startup' script in the src directory instead of manually executing them. Try booting with it instead.

Offhand I don't know if that will change anything. Are you crashing when you boot or when you try to copyover? The copyover_recover function should not be called during boot, so if it crashes during boot then that tells us something about the error. However, since you said you got the 'The world spins' message that would seem to indicate to me that it crashes when executing the copyover.

I would expect a crash with an empty file. The copyover_recover function requires data be specifically formatted in that file and it is not flexible about its handling.

SmaugFUSS is actively maintained and is usually pretty reliable. The message about IMC2 (which you don't actually post) sounds to me like the standard warning message which you can just ignore.

I hadn't noticed the startup scripts until you mentioned them!
Unfortunately whenever I try to boot up from the startup script it just does nothing.. no message, no error.. just nothing. Could this mean that it successfully booted up without any errors or am I being too hopeful?

I would assume startup might be a fresh boot while the executable tries to continue from the last savepoint during a copyover? I have no clue though.
But yes, the copyover error is during the first boot, strangely enough.

I'm thinking it may just be all the files from that website, I'm going to see if I can't get my hands on code from other sites and see if they give me the same errors.

Yes, actually. I usually have SmaugFUSS running on my Ubuntu PC for testing my client. On the few occasions I have to reboot it I can do this:


nick@bacall:~/smaugfuss/src$ ./startup


Note, no message (the script is actually running on this terminal with the output redirected). Or:


nick@bacall:~/smaugfuss/src$ ./startup &
[1] 11274
nick@bacall:~/smaugfuss/src$


This has "backgrounded" the startup script as process ID 11274.

Or to make sure it stays even if I log out of Ubuntu:


nick@bacall:~/smaugfuss/src$ nohup ./startup &
nohup: ignoring input and appending output to `nohup.out'
[2] 11325
[1]   Done                    ./startup
nick@bacall:~/smaugfuss/src$


The "nohup" command (no hang-up) means to keep the process running even if you "hang up" the connection.

Rather than assuming it didn't work, try connecting once you have run the startup script.

What I do to check if it is running with "ps" (process snapshot). By using the "a" option you look at all processes, and then filtering with grep you narrow down to ones with a particular name. In this case I see two processes, one being the one doing the "ps" and the other being the running server (process 11331).


nick@bacall:~/smaugfuss/src$ ps -waux | grep smaug
nick     11331  0.5  0.9   9892  6312 pts/0    S    07:40   0:00 ../src/smaug 4020
nick     11333  0.0  0.1   3240   796 pts/0    S+   07:42   0:00 grep smaug
nick@bacall:~/smaugfuss/src$

Got it running!

Thanks for the help,
I should've tried to connect after running startup but I thought it would atleast display a port to connect to if anything, but I managed to find the port using the ps command you showed me (then I figured out it gets setup within the 'startup' file).

Backgrounding the server & making it so it won't shutdown even with a logout will definitely come in handy.

Really do appreciate the help, I wouldn't have been able to figure it out on my own, thanks again.
