Having a bit of a puzzle with a package at work (which I can't share). In src/Makevars I override CC, CXX, CXX11, CXX14 to point to a specific (version) of g++ on my system, say g++-x.y. I also set CXX_STD=CXX14 Only it doesn't work. I need an extra dot.RMakevars and an invocation via R_MAKEVARS_USER=~/git/thatpackage/dot.RMakevars R CMD INSTALL . or else the values from R's default Makeconf come through. How could that be? I have invoked R CMD INSTALL probably thousands of times, and most got it to what I wanted but setting values in it. What could be wrong here? R 3.4.2; Ubuntu 17.04. Puzzled, Dirk
According to section 1.2.1 "Using Makevars" in Writing R Extensions, R_HOME/etcR_ARCH/Makeconf is included after Makevars, so what you're seeing is by design. I believe this is so that packages are built with tools compatible with those that built R. (Remember, packages are designed for distribution to diverse systems.)
If you happen to know how to override some of these settings in a safe way on your own system, then do what you did (as recommended in the R Admin manual, section 6.3.3.)
