Argument type to objc_enumerationMutation is ‘id’ which is translated into what ‘id’ is typedef’ed to; “struct objc_object*”. If projects have forward declaration of objc_enumerationMutation in their header files, this will cause conflicting types error for objc_enumerationMutation. - Fariborz > > Cheers, > Rafael > <t.patch>_______________________________________________ > cfe-commits mailing list > [email protected] > http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
