Hello all,
I've tried using the Swift 2.2 compiler from swift.org to compile a
simple sample project locally on OS X containing nothing besides a
hello-world example and a basic Package.swift but am failing to do so
due to several "Undefined symbols for architecture x86_64".
The sample project is as simple as possible with only a Package.swift
and a Sources directory containing a main.swift with nothing but a
print() statement. There is nothing declared in the Package.swift
besides the name of the module and an empty dependencies array.
This is the complete output from running `swift build`:
Compiling Swift Module 'foo' (1 sources)

"-f", "/Users/kilian/Desktop/foo/.build/debug/foo.o/llbuild.yaml"]
This minimal example seems to be working fine on other installs of OS X
and also inside an Ubuntu VM.
Any help on how to fix this would be much appreciated. Anything I can
find online on this refers to adjusting Xcode build setting to link with
external libraries.
There's also a StackOverflow question for this here[0].
Thank you very much in advance!
