| How did you add Lua, exactly?
It looks like it is crashing on looking up the function killed_mob in global script space. Next time, can you print L_mud? Maybe it is not set up for some reason. Or, it got corrupted. |

| I just copied the files over and added it by finding everywhere it was done in 1.8.
(gdb) print L_mud
$1 = (lua_State *) 0x0
(gdb)
There's L_mud, guess nothing is being given to it.

| It is NULL, which means the Lua engine was never initialized. I would check the part of the code which does that.
Check where you have put the lines:
open_lua (ch); /* fire up Lua state */
I would put a breakpoint there in gdb and see if that line is being called (probably not, I guess). If not, I would work out why not. |

| I hadn't added:
log_string( "Initializing Lua" );
open_mud_lua (); /* initialize Lua engine */
Right before the Booting Database in comm.c.
It's working now. | | Top |
