Charles,
Including another SDK's includes manually won't work, because you can't
mix SDKs - and you shouldn't need to do that.
If in doubt, run sudo xcode-select --install which will install any
missing tools - you still do need regular Xcode installation in addition
to the clang+fortran compilers. You shouldn't need to touch CPPFLAGS -
if you do, something is broken in your system.
Simon,
Thanks for the reply. As of yesterday, everything seemed to be working OK
without any ~/.R/MakeVars file. viz, I can compile packages using the
binary you provide for R-3.4.0. Also, I can configure, make, and make
check R-devel using the clang4 you provide.
I can't say what is different now from before. I just updated pcre and
added pkg-config, java JDK, and cairo. I recently re-installed command
line tools, but I have had these `forever'.
Anyway, all is now well.
Thanks,
Chuck

TL;DR: I can compile C/Fortran to install packages that need
compilation, but I get loads of warnings. I must have quirks in my
setup, possibly including the need to add system header files
compatible with clang4.
