Project failed to compile on OS X Yosemite using Xcode 6.4

[mrfortynine]

The clang compiler complain about "/Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.10.xctoolchain/usr/include/c++/v1/atomic:632:58: No viable conversion from 'std::__1::chrono::duration<long long, std::__1::ratio<1, 1000000000> >' to '_Atomic(std::__1::chrono::duration<long long, std::__1::ratio<1, 1000000000> >)'
"

in MapData's constructor, as chrono::duration isn't trivially copyable.

I’m not seeing this error building for iOS 8.4 in Xcode 6.4 on Yosemite. Can you provide additional details about your setup?

• Which target are you building?
• Did you make any modifications to the workspace before building, such as integrating your own project or changing the C dialect or minimum deployment target in the build settings?
• Are you building for the device or a simulator? Which simulator?
• Are you building inside Xcode or on the command line via make ipackage / xcodebuild?
• Does this error persist after going to Product ‣ Clean Build Folder (hold down Option)?

[1ec5]

Also, are you building a workspace that was generated via make iproj (for iOS) or make xproj (for OS X)?

[mrfortynine]

I was building for OS X, not iOS device of simulator. I used "make xproj", after which, I attempted to build target "All". The error is reported for "core".

The error persists after a clean.

Here's the complete error message:

I’m seeing #2025 instead. In any case, I think it may be a regression from #1988, which started pulling in boost from mason instead of using the system’s copy.

The OS X have been completely rewritten in #3135. Please let us know if you’re still seeing this error. Thanks!
