Just in case anyone was wondering how to do this with the other major Haskell GUI lib Gtk2Hs... ./configure --enable-profiling some day when Gtk2Hs is cabalised it'll be even easier. Duncan On Sun, 2007-05-20 at 17:39 +0200, Anthony Chaumas-Pellet wrote:
Hello,
I'm currently hacking away a wxhaskell program that uses up 100% CPU even when it should be idle. So, rather than doing blind guesswork, I've thought about using profiling to spot the zealous function. I do not need a very accurate result, though.
ghc with -prof -auto(-all) produces the following error message, however: "Could not find module `Graphics.UI.WX': Perhaps you haven't installed the profiling libraries for package wx-0.10.1? Use -v to see a list of the files searched for."
So, I guess I need to rebuild wx with profiling, but I'm not sure how to do that exactly; <search engine> and the Wiki did not turn up any pointers, and there are no ready-made options to build wx with profiling. It seems Cabal can build a library with profiling automatically, but I don't think there exists a Cabalized version of wx yet.
That, and I'm not sure if recompiling libraries to add profiling is a great idea, as wx itself may depend on other external libraries. So, is there a better way than profiling in my case, or am I missing something obvious here?
