[swift-corelibs-dev] Unresolved enumeration symbols

Sat Dec 12 22:27:44 CST 2015

Installing Ubuntu 15.10 on a VM, bringing in all of the prerequisites, I
get the same result.  The build completes successfully but libFoundation.so
is not including the enumerations in NSDateFormatter.

public enum NSDateFormatterStyle : UInt {
    case NoStyle
    case ShortStyle
    case MediumStyle
    case LongStyle
    case FullStyle
}

For grins, I searched through libFoundation.so with nm -D looking for
another enum, say one of the NSNumber format styles:

$ nm -D libFoundation.so |grep CurrencyStyle
$ nm -D libFoundation.so |grep PercentStyle

No dice, Chicago.

I can't say all enumerations are missing but these definitely are.

I've also posted what I use to prep and build at
https://github.com/iachievedit/package-swift; hoping there isn't an
embarrassing oversight.
