netmud

I've been trying to compile my mush, and I've encountered this error:

mv: cannot stat 'netmud': no such file or directory


I know where the netmud.pid file is, but as I'm a bit new to this, I'm not sure what to do to correct the error. Any help would be appreciated, thank you.

Which version are you compiling? I think the latest is available on GitHub:

https://github.com/pennmush/pennmush

What operating system are you using?

Fritz #2
The version of Pennmush we're using is 1.8.6p2, and the OS on the server is AlmaLinux v 8.10 (Cerulean Leopard)
Nick Gammon Australia Forum Administrator #3
Does this error occur during compilation, or afterwards when you try to run the MUSH?
Fritz #4
It happens when I'm compiling the mush.

Well, I just downloaded, compiled and ran the latest version, as follows:


git clone https://github.com/pennmush/pennmush.git
cd pennmush
./configure
make update
make install
cd game
./netmush


No errors. Note that the executable file was netmush and not netmud.

This was on Ubuntu 22.04.
Fritz #6
I just checked again and the error when compiling is is netmud, but it's netmush.pid that I have.

It's not a new install, but moving from one server to a new one. I can do everything to compile an existing mud, but when I try to sh restart in cd/pennmush/game it tells me:

running from home/fritz/pennmush/game
i don't see home/fritz/pennmush/game/netmush. Did you remember to make install?

And the answer is yes, I did make install.
Nick Gammon Australia Forum Administrator #7
I'm confused about this talk about netmud.pid. A xxx.pid file is not usually an executable file.

You should be running netmud (or netmush depending on the name) not netmud.pid.

Please do an "ls -l" of pennmush/game and post the results here.

netmush.pid is just a 5 byte file. That is not the server.

I cannot see netmush or netmud in that directory, so you need to find where it is, if it exists at all.

You can see that netmush is a link to ../src/netmud
Fritz #11
There's a 4.00MB file in src called netmud~ and that's all I can find. Not sure if that's the correct one or what to do with it if it is.
Nick Gammon Australia Forum Administrator #12
In the game directory, make a soft link to netmud, like this:


ln -s ../src/netmud netmush


Then type:


./restart


That should start it up.
Fritz #13
[fritz@zeus ~]$ cd pennmush/game
[fritz@zeus game]$ ln -s ../src/netmud netmush
[fritz@zeus game]$ ./restart
Running from /home/fritz/pennmush/game

No luck. >.<
Nick Gammon Australia Forum Administrator #14
Do another "ls -l" and show the results.
Nick Gammon Australia Forum Administrator #15
In your "src" directory you should have various .c and .o files, including "netmud" which is the final result of compilation, like this:

Now, if you have "netmud" there then when you are in your "game" directory this simple command should run the MUSH:


./netmush mush.cnf


Or, if the "ln" I suggested did not work for some reason, simply do this:


../src/netmud mush.cnf

the only netmud i can find in src is netmud~ , no .c or .o file

If the link is in red then the file netmud does not exist, because the compilation failed. There won’t be a netmud.c - the netmud file is the result of linking all of the .o files together.

Your original error report:

mv: cannot stat ‘netmud’: no such file or directory

… would seem to be the effect of the compilation failing, not the cause. You probably had other error messages which result in not getting the netmud file produced.

Is there any reason you don’t just download and compile the latest version as I did in an earlier reply? Then you can copy the netmud file to your existing src directory and everything should work (assuming you have an existing database you want to keep using).

Fritz #18
I just wasn't sure that I could do that and didn't want to risk it. I asked people more experienced than me and always got an unsure reply.
Nick Gammon Australia Forum Administrator #19
Make a backup of your database (which you should be doing anyway). The worst that could happen is that it doesn't work, and you have to go back to the backup.
Nick Gammon Australia Forum Administrator #20
The database should be in the "data" directory, you should see files like this:

If you have an existing MUSH the file indb.gz and outdb.gz should be much larger. I would back up that entire directory.
Fritz #21
I got netmud and copied the file over, mush starts, but none of the previous database is loading.

I’m confused about your directory setup. I’m guessing, but don’t know because you don’t give a whole lot of detail, that you have:

  • Your existing MUSH in some directory

  • The one you were compiling which didn’t fully compile in another directory.

  • The one you downloaded as I suggested in a third directory.

I am guessing that you are running the MUSH (netmud) from a directory that is not finding the database.

Fritz #23
Actually there's only one directory uploaded to the server my friend is letting me use, which is the directory of the existing mush, which is what I was trying to compile to work on that server before. I had been using a hosting service before but was forced to move because they're shutting down, and I've never had to move from one server to a new one before.

I downloaded the new instance of Pennmush to my pc and uploaded netmud into the server directory from there so there'd be no cross contamination, so to speak.

I did notice something strange after I restarted the Mush to try to get it to recognize the database: outdb vanishes from the data folder after a restart.

Nick Gammon Australia Forum Administrator #24
Check out the contents of mush.cnf file. Part of it has the paths to the database, perhaps that does not agree with your setup:


# Databases
# These are, respectively, where to read a database, where to
# write a database, where to put a panic dump (performed if
# the MUSH determines it's going to crash, where to put MUSH mail,
# and where to keep information about the chat system.
# Filenames are relative to the game/ directory.
#
# Do NOT put compression suffixes at the end of the files.
# That's handled below
#
input_database data/indb
output_database data/outdb
crash_database data/PANIC.db
mail_database data/maildb
chat_database data/chatdb


Also, post any messages that appear when the MUSH starts up, perhaps it is not finding your database and is saying so.
Fritz #25
I'll have to ask Opie what the correct path is because I tried to edit it to what I thought was correct previously to this, and I just got a message saying it didn't recognize those paths.

I'm not on my pc right now, but when I have an opportunity I'll post what it says when I start the MUSH.
