What are your arguments to xcodebuild?
None. I open the Xcode project in Xcode and click the Run (Play) button. That seems to be a way which should work. Otherwise, I'm not sure why there's a Xcode project file. target is libsystem_c.dylic. I've tried other targets without any success.
What is the build failure you are encountering?
Depending on the Xcode version (4.6.x or 8.0, there between 120 and 260 reported errors).
Can you provide a build log?
Most of the errors are related to files not found in <sys/_something>. This "_" prefix is a bit weird for me.

Regarding releases of newer versions, it usually takes a little while after GM for the OSS drop.
I don't think it's an issue here as the source code for the function I want to investigate has probably not changed in years. _______________________________________________ Do not post admin requests to the list.
