When linking Mapbox GL as a static library, the object file (MGLFoundation.o) containing the global static variable initialization was not linked into the resulting binary since it was not referenced. This resulted in the RunLoop not being initialized in the main thread.

Darwin
The code in the Darwin platform targets Apple platforms but is not specific to iOS or macOS. This code is not distributed as an SDK in itself, but is required by the Mapbox iOS SDK and Mapbox macOS SDK.
These files depend on the Foundation and Core Foundation frameworks but do not depend on iOS- or macOS–specific frameworks, such as UIKit or AppKit. Any non-cross-platform code is guarded by TargetConditionals.h macros.
