C++ is so much nicer than C, it’s embarrassing how long I’ve taken to switch. But wow, compilation is slow. Reminds me of my 80s tape drive.

@wrathematics Oh, yeah; totally! I’m with you on that point.

@kwbroman are you using clang?

@hadleywickham yes

@kwbroman well you've already done the best thing to make compiles fast and errors understandable

. @hadleywickham @kwbroman Best thing since sliced bread is ccache from the Samba project -- perfect for repeated R CMD build calls

@eddelbuettel use (e.g.) CXX=ccache clang++ in ~/.R/Makevars?
