[R-SIG-Mac] Xcode 10.3 and header flles

[Simon Urbanek]

Roy,

that shouldn't be necessary if you use the CRAN release since it specifically points to the SDK. If you are compiling your own R you may want to add
CPPFLAGS='-isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -I/usr/local/include'
which is what the CRAN build uses. FWIW you can always check the current flags at
https://svn.r-project.org/R-dev-web/trunk/QA/Simon/R-build/conf.el-capitan-x86_64
 
If the above doesn't address the issue you're seeing, please provide details.

Thanks,
Simon
