Description
While compiling CFString on ARM (Raspberry Pi 2) I am running into a perplexing issue. It appears that the va_list typedef is being defined multiple times.
<module-includes>:1:10: note: in file included from <module-includes>:1: #include "CoreFoundation.h" ^ /home/ryan/Source/swift-corelibs-foundation/../build/Ninja-ReleaseAssert/foundation-linux-armv7/Foundation/usr/lib/swift/CoreFoundation/CoreFoundation.h:58:10: note: in file included from /home/ryan/Source/swift-corelibs-foundation/../build/Ninja-ReleaseAssert/foundation-linux-armv7/Foundation/usr/lib/swift/CoreFoundation/CoreFoundation.h:58: #include <CoreFoundation/CFCalendar.h> ^ /home/ryan/Source/swift-corelibs-foundation/../build/Ninja-ReleaseAssert/foundation-linux-armv7/Foundation/usr/lib/swift/CoreFoundation/CFCalendar.h:21:10: note: in file included from /home/ryan/Source/swift-corelibs-foundation/../build/Ninja-ReleaseAssert/foundation-linux-armv7/Foundation/usr/lib/swift/CoreFoundation/CFCalendar.h:21: #include <CoreFoundation/CFTimeZone.h> ^ /home/ryan/Source/swift-corelibs-foundation/../build/Ninja-ReleaseAssert/foundation-linux-armv7/Foundation/usr/lib/swift/CoreFoundation/CFTimeZone.h:23:10: note: in file included from /home/ryan/Source/swift-corelibs-foundation/../build/Ninja-ReleaseAssert/foundation-linux-armv7/Foundation/usr/lib/swift/CoreFoundation/CFTimeZone.h:23: #include <CoreFoundation/CFString.h> ^ /home/ryan/Source/swift-corelibs-foundation/../build/Ninja-ReleaseAssert/foundation-linux-armv7/Foundation/usr/lib/swift/CoreFoundation/CFString.h:265:123: error: reference to 'va_list' is ambiguous CFStringRef CFStringCreateWithFormatAndArguments(CFAllocatorRef alloc, CFDictionaryRef formatOptions, CFStringRef format, va_list arguments) CF_FORMAT_FUNCTION(3,0); ^ /home/ryan/Source/build/Ninja-ReleaseAssert/swift-linux-armv7/lib/swift/clang/include/stdarg.h:30:27: note: candidate found by name lookup is 'va_list' typedef __builtin_va_list va_list; ^ /usr/include/stdio.h:79:20: note: candidate found by name lookup is 'va_list' typedef _G_va_list va_list;
It would seem that va_list is being defined by multiple things in the include path.
