[help-3dldf] RE2: Run Errors

[Glen Ritchie]

Hi Laurence,

***
Just read your new email on bugs-3dldf.

***
The run2.ldf, which is abc.ldf (from the emails). 

> declaration --> picture_declaration

Yes, you are right. The run command was

>> (gdb) run --multithread-input --multithread-output 
abc.ldf

My mistake.

***
Don't use 'gdb'? Just run outright.

How do I 'selectivly' turn on debugging for that
class's
destructor? Are you suggesting edit the code?

> 3. Turn debugging output on in `~Mutex_Type()'.

I would trying changing the value of the Point
variable 'p'
in this sample. But, which file are you talking about
(*.web source)?

Or do you mean with an input file?

Yes, I'm quickly getting confused. This is going to
take
more time.

It'll have to wait till the weekend. When I can spend
some
time looking over the whole package. Besides, I need
to
read up on MetaPost.

Glen

PS. Ok, you beat me replying to my own message.

I'll send this and see what you said, already, next!!!
