Bug 135339 – REGRESSION: unknown type name 'qos_class_t' in iOS 8.0 beta 4

• Status: RESOLVED
• Resolution: INVALID
• Component: JavaScriptCore

[Isaac Burns]

Error when including /usr/include/dispatch/dispatch.h.

[Alexey Proskuryakov]

Could you please post a complete test project?

[Isaac Burns]

I'll see if I can get a smaller test project put together.  The full project involves attaching libuv to JSC.  From what I can tell, the only thing included before <JavaScriptCore/JavaScriptCore.h> is "uv.h".

The following conditional in qos.h is failing, leaving qos_class_t undefined.

/Applications/Xcode6-Beta4/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.0.sdk/usr/include/sys/qos.h:30

#if __DARWIN_C_LEVEL >= __DARWIN_C_FULL

How about adding a fallback for the other cases, as in .../usr/include/dispatch/queue.h:370?

#else
typedef unsigned int qos_class_t;
#endif

[Alexey Proskuryakov]

If you think that the problem is in qos.h itself, then WebKit bugzilla is not the right place to discuss it, we don't maintain it. Could you please file a bug with more details via <http://bugreport.apple.com>?

Done.  Problem ID 17844922.

Thank you! Let's have it tracked there.
