Hi Jules. Congrats on Grapefruit Juce. Sounds great.
I just built the UnitTestRunner but when I ran it the previously mentioned CoreImage.framework problem reared it's ugly head:
Daves-MacBook-Pro:~ davechambers$ /Users/davechambers/...../JUCE/extras/UnitTestRunner/Builds/MacOSX/build/Debug/UnitTestRunner ; exit;
dyld: Library not loaded: /System/Library/Frameworks/CoreImage.framework/Versions/A/CoreImage
Referenced from: /Users/davechambers/........./JUCE/extras/UnitTestRunner/Builds/MacOSX/build/Debug/UnitTestRunner
Reason: image not found
Trace/BPT trap: 5
It also has the annoying consequence I cannot profile my code in Instruments :
Hope you can fix it.
