I just added lua into 1.9 and get a crash on add_kill.

Tried killing Chadoyn and got this:

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.

Did you find it easy to get lua into 1.9

Everything turns around in the end
