Unable to install on Windows; passes c++0x instead of c++11

I am on Windows 7 64bit using Rtools 3.3.0 v1959, and can build R (building R-patched_2016-03-28) and pretty much every package from source successfully. However, when trying to install feather via devtools, I get the following. Please note that somehow, c++0x is being passed even though my .R/Makevars has CXXFLAGS = -std=c++11 (which manifests properly in every other package, such as Rcpp). Would that have anything to do with the issue?

Also, as it seems to have an issue with api.h, does it matter that the file is actually at “feather/cpp/src/feather/api.h” and not in the feather/R subdirectory?

Thank you.

I still think it is you. On my (non-Windows) system:

edd@max:~$ R CMD config CXX1XSTD
-std=c++11
edd@max:~$ 

I have looked at length into how R gets these values, and invariable you get back to RHOME/etc/Makeconf. Unless you built R with g++ 4.9.3 you will have c++0x here. And even if you did maybe R still gets this wrong on Windows as 4.9.3 is no new. But I (again) suggest you check your Makeconf file. Not the local override – the one R falls back to.

@eddelbuettel I thought about on the rest of the ride home, and I think you are correct. There are too many issues going on in this one. As the two I started with are answered, I’ll close this and open a new one. Thank you and @wesm again!
