By the way... does ticky-ticky allow monitoring multithreaded programs? I ask this because the other way of learning data about the execution (compiling with -prof) is not compatible with -threaded options. In other words, you can't compile a Haskell program with -prof and -threaded options at the same time. Cheers. Cristian On 8/1/07, Tim Chevalier wrote:

Hi all!. I modified build.mk in order to allow Ticky-Ticky profiling (GhcLibWays=t). Now, when I try to make I get this error:

Hi, Cristian-- To get ticky to work, you need the HEAD (or a recent nightly build snapshot). If it's still not working after that, post again.

Cheers, Tim

Sorry, It looks like I haven't been precise with my question: I wanted to say multiple hardware (it implies OS) threads. In other words: are -threaded and ticky ticky compatible? Will I be able to run "./myProgram +RTS -N4 -rmyout.ticky" ? Hope my doubt is clearer now. Regards. Cristian On 8/2/07, Stefan O'Rear wrote:

at the same time.

You don't need -threaded to run multithreaded programs.

-threaded will make them run *faster* on >1-core machines, but the normal RTS will run multiple Haskell threads just fine on its single OS-thread.
