import Foundation => could not build Objective-C module 'CoreFoundation'

Andrew_Cornett · 2017-01-18T14:57:18.000Z

Has anyone been able to `import Foundation` using a development snapshot on Ubuntu 14.04? I'm getting errors that make it seem like my environment isn't setup correctly, but the same environment works fine for the 3.0.2 release.

I've tried manually providing some include paths to the swift command, which did remove the SwiftGlibc error, but nothing else seems to be working out for me :-(

This sounds like we’ve included a header which does not exist on Ubuntu 14.04 in CoreFoundation.h.

github.com

apple/swift-corelibs-foundation/blob/main/CoreFoundation/Base.subproj/SwiftRuntime/CoreFoundation.h#L36


      
          #include <stdarg.h>
          #include <assert.h>
          #include <ctype.h>
          #include <errno.h>
          #include <float.h>
          #include <limits.h>
          #include <locale.h>
          #include <math.h>
          #if !defined(__wasi__)
          #include <setjmp.h>
          #endif
          #include <signal.h>
          #include <stddef.h>
          #include <stdio.h>
          #include <stdlib.h>
          #include <string.h>
          #include <time.h>
          
          #if __has_include(<netdb.h>)
          #include <netdb.h> // for Host.swift
          #endif

but that include has been there since the beginning… (and the sys/types.h include)

All of the headers failing there are headers which should be found with the Clang compiler headers, which ship inside the snapshot (and are keyed by compiler version).
