I tried to port package
dmenne/breathteststan (github, CRAN) to use the stucture of rstantools 2.0.0. Works fine in my local Windows build, but gives the well known
C++14 standard requested but CXX14 is not defined on r-hub (https://builder.r-hub.io/status/breathteststan_0.4.7.9000.tar.gz-be031122f1124ebc8ae7c363a5f2d0ca). r-hub Mac build is fine.
Since makevars.xxx is now generated by rstanstools, I don’t want to change it using one of the old methods. Any suggestion?
