Given the output below, it looks like you're building it against the DevSDK (the SDK installed to / when you install the Xcode Command Line Tools package) because there is no -isysroot command line argument. At minimum, you should be building it against an SDK that matches the OS that it came with.

There's nothing to "run" so Build & Run doesn't really make sense. I suggest you start from the command line like:

xcodebuild -sdk macosx -target libsystem_c.dylib

Noted.

You may run into issues due to internal headers being included (sys/_pthread/_pthread_types.h isn't such a case, it's in /usr/include). If that's the case, you'll want to fix that up yourself either by grabbing the internal headers out of other OSS packages or disabling that functionality in Libc.

Will try on a 10.11.5 system as on 10.12, the command line call results in 1,267 errors at build. Thanks. _______________________________________________ Do not post admin requests to the list.
