was using the Oasis OLC code submitted here by Vladaar and getting this

act_move.c:3383:14: error: ‘edir’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
     move_char( ch, get_exit( ch->in_room, edir ), 0 );
     ~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

edit: This is the buildwalk part of the code
Anyone else used this on SmaugFUSS and get it working?

ok not sure if it is a 'solution', but I just commented out that line and everything works fine.

Wherever edir was declared you should do...

Change it to short edir =0;

That initializes it.

I would uncomment that movechar call I'm sure you need it.
