Re: [Haskell-cafe] Threadscope 0.2.2 goes in segmentation fault on Mac Os X 10.8.3
Hi Alfredo, No dark magic as far as I recall (except in the actual bundling as a Mac app, unfortunately that required some magic, the GTK libraries don't relocate so easily :-( ). I didn't have any problems building. I compiled it with ghc 7.6.1, with the GTK libraries installed manually (there are some suggestions on how to do that at the very end of my Comprehensive Haskell Sandboxes post, http://www.edsko.net/2013/02/10/comprehensive-haskell-sandboxes/). It used to be a lot more painful (requiring the latest versions of Haskell libraries, with patches etc.) but these days the situation is a lot better. (That's not so say that problems like the one you reported don't still crop up from time to time, and can cause many a sleepless night..).

Hi Edsko, thanks for the reply. The only things that might affect the outcome are: a) Ghc version: I'm running ghc 7.6.2 instead of 7.6.1 b) Don't know if you are using cabal-dev as sandboxing (like any good Haskell programmer I'm too lazy to open your blog post :D ), whilst I'm using hsenv c) I've brewed GTK instead of manually installing it, but gtk-demo runs just fine d) Are you using XQuartz?

a) 7.6.2 vs 7.6.1 seems unlike to be the issue, although theoretically possible I guess. b) Actually, the blog post is how to set things up by hand for better control than either of those tools give you; but again, I don't think it's relevant. c) This might be a bigger difference.
