It is called -O3, not 'O3'. (Also Rcpp, not RCpp.) We do not know what you did because you never posted anything even remotely close to reproducible. | Maybe I should just give up RCpp and move the program entirely to C++ from now | on. Whatever works for you. You could also look at some existing projects and see what they do; I just did a quick recursive search below my git directory on the machine and saw at least two packages set -O3. So it works for some of us. Good luck either way.
