Ubuntu 20.04 problem...

hi, i'm approcing to compile smaugfuss1.9, but i have a lot of errors like:

calendar.c:504:22: warning: ISO C++ forbids converting a string constant to ‘char*’ [-Wwrite-strings]

In make file i did try to comment:

IMC in Makefile. That at least stops the errors in the imc.c file.
On the line "W_FLAGS" (in Makefile) remove: -Werror

but not compile yet...
I have gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.1)

Some help? thanks

Warnings won't stop it compiling unless you have -Werror flag set.

If there are other messages which actually are errors please post those.

I think there is a flag in the Makefile to omit including IMC at all, which you probably don't need.

sorry, i did try the smaugFUSS version 1.9.4 2019-16-03 17:32:06

compiling appear ok, but when insert nohup ./startup &


make -s smaug

serena-maurizio @ R2-D2: ~ / C / MUD / extra / SmaugFUSS-master / src $ nohup: input ignored and output appended to 'nohup.out'
nohup: unable to execute command './startup': Permission denied

chmod +x startup

when insert chmod +x startup nothing appen..none error and not run server.

Anyway in SRC folder startup.h lacks.. there is only startup.

Try running your nohup command again now.

Doing the command `chmod +x startup` adds the permission to execute the file named startup. You said you got a permission denied to execute startup error message. Therefore, adding the execute permission should fix the problem.

i did try:

serena-maurizio@R2-D2:~/C/MUD/extra/SmaugFUSS-master/src$ chmod +x startup
serena-maurizio@R2-D2:~/C/MUD/extra/SmaugFUSS-master/src$ nohup ./startup &
[1] 10220
serena-maurizio@R2-D2:~/C/MUD/extra/SmaugFUSS-master/src$ nohup: input ignorato e output accodato a 'nohup.out'


return this error: input ignored and output appended to 'nohup.out'

Try this:



That is basically what the startup file does.

work! by
cd ../area
../src/smaug

but after some time server block and report this error:

The weather updating code looks bugged to me.

Try applying the changes I proposed here: https://github.com/Arthmoor/SmaugFUSS/issues/5

now work, thanks.
Now i must understand why reboot not work . And maybe some others thinks.

You do not "insert" that command into startup. You do it to the startup file.

If you startup file does not have execute permissions you cannot run it the way you did. An alternative is to do:
