Re: [Haskell-cafe] whhaskell on osx 10.5

wxHaskell - Building - MacOS X (http://wxhaskell.sourceforge.net/building-macosx.html):

Due to complicated MacOS X restrictions, graphical wxHaskell applications do not work directly when used from GHCi. Fortunately, Wolfgang Thaller has kindly provided an ingenious Haskell module that solves this problem. Just import the (compiled) module EnableGUI in your program and issue the following command to run main from your GHCi prompt:

...

enableGUI >> main

Is there any estimated date on getting graphical wxHaskell applications to work directly when used from GHCi? Benjamin L. Russell --- On Wed, 5/21/08, Kirk Peterson wrote:

will work fine on windows and linux, under mac os, I ran into issues with window focus and click events not firing. Upon looking further, I found this page on the wxhaskell site: http://wxhaskell.sourceforge.net/building-macosx.html

which explains the need to the macosx-app step in compiling a whhaskell app, and why I include it in my example. Hope this helps.

working here:

I've never used a Mac.. Why do you run macosx-app ?

Doesn't $ ./helloworld work?
