I've just updated the JUCE lib from 2.1.1 to the latest tip and it's coming up with a couple of "Undefined symbols for architecture x86_64" when setting the base SDK to 10.5.
The errors I'm getting are:
Undefined symbols for architecture x86_64:
"__Block_object_assign", referenced from:
___copy_helper_block_ in juce_events.o
"__Block_object_dispose", referenced from:
___destroy_helper_block_ in juce_events.o
"__NSConcreteStackBlock", referenced from:
juce::repostCurrentNSEvent() in juce_events.o
ld: symbol(s) not found for architecture x86_64
All is fine when set to 10.6 or above though. Is there a fix for this?
