<tr1/memory> file not found

With a latest cedar I followed the instructions on how to install it and create a new spec target suite. However when I build I always get this error:

[tr1/memory] file not found

I use XCode 4.5 and I tried to perform the actions on a celan new project just to make sure that my settings are not the reason.

Ok I got this resolved by changing the C and C++ dialects to the C99 and C++98 as they are in the sample. The default values are different.

This was a change in Xcode 4.5. Prior to iOS6 the default C++ library was
C++98; they have now changed the default to C++11. Older devices with
older iOS versions do not have the newer C++ library available, so we stuck
with the older library version for compatibility. Now that Apple has
changed the default we'll most likely change over to the newer library, but
doing so can potentially break existing projects, so we need to be a bit
careful about it.

I have added stories to our public tracker project to track the migration to C++11.

"Move to C++11 for Specs" https://www.pivotaltracker.com/story/show/36163315
"Release and document last release to be compatible with 4.x" https://www.pivotaltracker.com/story/show/36190725

Please refer to them for future updates.

Thanks for your feedback!

I've pushed a commit to master (9ceb06e) which updates Cedar to use the
C++11 standard library. There are a couple things to note about this
change:

1. New iOS projects will select the C++11 dialect and standard library by
   default, but these are not the compiler defaults for the current version
   of LLVM. If you select "Compiler default" for either the C++ Language
   Dialect or the C++ Standard Library it will revert to using C++98.

2. Xcode disallows using C++11 for any iOS deployment target earlier than
   5.0. If you plan to target an earlier iOS version, and you want to run
   your specs against the older iOS version, you'll need to revert back to
   using C++98.
