Recently pulled some code to a new system, and I'm having some trouble compiling chrono_io and ratio_io.
I'm unsure what to change, since the errors appear to affect the preprocessor.
It seems like it must be a cross-platform compatibility issue for which the code doesn't account.
Any ideas how I can resolve these preprocessor and compiler errors?

I haven't played with this code in several years. It is using:
to check if the compiler supports rvalue references (C++11 move semantics). My recommendation is to assume that you have C++11 (since you have to have
<chrono>and just remove the__has_featureand the#elsebranch.If for some reason you have to support a compiler which doesn't have rvalue references you can:
and this will select the
#elsebranch everywhere.__has_feature(cxx_rvalue_references)is a clang extension.Update
Update to this library.

It has been simplified to only streaming durations.
