Profiling programs

[Bernd Gutmann-3]

Hi.

I wanted to use the tick profiler to see how slow my programs really  
are.
The YAP docu says,
that :- profinit. will switch it on and :- profon. will start the  
profiling.

Unfortunately, both times YAP answers No.
Do I have to configure YAP with some extra flags? Currently, I don't  
give any.
And if, which would it be? The docu is not very specific about that.

I tried already
  --enable-wam-profile
but YAP wouldn't compile (under Mac OS X, latest yap-5 from GIT).

Any ideas?
Bernd

Current development is focused on the yap-6 git. I suggest you try  
this version instead.

Cheers,

I'm sure they're fast :)

That works fine for me and needs no special flags, but Paulo is right,
I mostly been using yap-6. Can you please give it a try, I remember
Leopard has made some changes to the interface so I may have disabled
it in yap-5 Leopard.

No.

The WAM profiler is really something that I use to check how many WAM
instructions were executed. It is unlikely to matter to you :)
