[swift-dev] Compiling on FreeBSD

[K Staring]

Hi,

While trying to port the current swift code to FreeBSD, some swift code fails to compile. The failures are concentrated in SwiftPrivatePthreadExtras.swift and code which depends on it.

Can someone shed some light on the following errors? I am having some difficulty understanding why the C headers would be interpreted so slightly differently than expected?

--(start compile failure)

  let result = pthread_create(&threadID, attr,
                                         ^~~~

--(end compile failure)

Thanks for any suggestions or pointers!
