Hi My first bite at installing wxhaskell on Mac OS Mavericks and I am almost there after jumping thru a few hoops. I am on wxhaskell 3.0 and installed the haskell platform using homebrew. I had to edit the Setup.hs to indicate I was on 3.0 not 2.9 as one of the hurdles to getting it even install. So this is what I get try to run HelloWorld.hs: make HelloWorld ghc -package wx -o HelloWorld HelloWorld.hs Linking HelloWorld ... ld: warning: ignoring file /System/Library/Frameworks//QuickTime.framework/QuickTime, file was built for i386 which is not the architecture being linked (x86_64): /System/Library/Frameworks//QuickTime.framework/QuickTime Undefined symbols for architecture x86_64: "_CPSSignalAppReady", referenced from: _s7vsd_info in libHSwxcore-0.90.1.1.a(GHCiSupport.o) ld: symbol(s) not found for architecture x86_64 collect2: error: ld returned 1 exit status make: *** [HelloWorld] Error 1 I did a search under /usr/local/Cellar for the QuickTime and found it in ./wxmac/3.0.0/lib/wx/config/osx_cocoa-unicode-3.0 and I removed the inclusion of QuickTime Framework, but it made no difference. Any help appreciated at this stage as I am feel I am so close to getting this to work. Paraic
