With the plethora of people who can't seem to wrap their minds around
grep'ing a file for where there's an error, here's an idea that should
stop these problems from showing up all the time...
>
If you get some errors, just recompile the mud with -DDEBUG_LOG in the
makefile; added to MYFLAGS at line 12 of the Makefile after -Wall
(so it would be like this:
MYFLAGS = -Wall -DDEBUG_LOG
It'll show you the file, function, and even the line number of every
single time log() is called.
For how to apply it, I refer you to section 2.7 of the FAQ that came
with the source.
Ignore the last patch, it forgot to update the __attribute__ definition
in the prototype for basic_mud_log().
